NAME
       javadoc - The Java API Documentation Generator


          Generates HTML pages of API documentation from Java source files.
          This document contains Javadoc examples for Sun Solaris.

SYNOPSIS
       javadoc [ options ] [ packagenames ] [ sourcefilenames ] [ -subpackages pkg1:pkg2:... ] [ @argfiles ]

       Arguments can be in any order. See processing of Source Files for
       details on how the Javadoc tool determines which ".java" files to
       process.

             options
                Command-line options, as specified in this document. To see a
                typical use of javadoc options, see Real-World Example.

             packagenames
                A series of names of packages, separated by spaces, such as
                java.lang java.lang.reflect java.awt. You must separately
                specify each package you want to document. Wildcards are not
                allowed; use -subpackages for recursion. The Javadoc tool uses
                -sourcepath to look for these package names. See Example -
                Documenting One or More Packages

             sourcefilenames
                A series of source file names, separated by spaces, each of
                which can begin with a path and contain a wildcard such as
                asterisk (*). The Javadoc tool will process every file whose
                name ends with ".java", and whose name, when stripped of that
                suffix, is actually a legal class name (see Identifiers @
                http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#40625).
                Therefore, you can name files with dashes (such as X-Buffer),
                or other illegal characters, to prevent them from being
                documented. This is useful for test files and template files
                The path that precedes the source file name determines where
                javadoc will look for the file. (The Javadoc tool does not use
                -sourcepath to look for these source file names.) Relative
                paths are relative to the current directory, so passing in
                Button.java is identical to ./Button.java. A source file name
                with an absolute path and a wildcard, for example, is
                /home/src/java/awt/Graphics*.java. See Example - Documenting
                One or More Classes. You can also mix packagenames and
                sourcefilenames, as in Example - Documenting Both Packages and
                Classes

             -subpackages pkg1:pkg2:...
                Generates documentation from source files in the specified
                packages and recursively in their subpackages. An alternative
                to supplying packagenames or sourcefilenames.

             @argfiles
                One or more files that contain a list of Javadoc options,
                packagenames and sourcefilenames in any order. Wildcards (*)
                and -J options are not allowed in these files.


DESCRIPTION
       The Javadoc tool parses the declarations and documentation comments in
       a set of Java source files and produces a corresponding set of HTML
       pages describing (by default) the public and protected classes, nested
       classes (but not anonymous inner classes), interfaces, constructors,
       methods, and fields. You can use it to generate the API (Application
       Programming Interface) documentation or the implementation
       documentation for a set of source files.

       You can run the Javadoc tool on entire packages, individual source
       files, or both. When documenting entire packages, you can either use
       -subpackages for traversing recursively down from a top-level
       directory, or pass in an explicit list of package names. When
       documenting individual source files, you pass in a list of source
       (.java) filenames. Examples are given at the end of this document. How
       Javadoc processes source files is covered next.

   Processing of source files
       The Javadoc tool processes files that end in ".java" plus other files
       described under Source Files. If you run the Javadoc tool by explicitly
       passing in individual source filenames, you can determine exactly which
       ".java" files are processed. However, that is not how most developers
       want to work, as it is simpler to pass in package names. The Javadoc
       tool can be run three ways without explicitly specifying the source
       filenames. You can (1) pass in package names, (2) use -subpackages, and
       (3) use wildcards with source filenames (*.java). In these cases, the
       Javadoc tool processes a ".java" file only if it fulfills all of the
       following requirements:

          o Its name, after stripping off the ".java" suffix, is actually a
            legal class name (see Identifiers @
            http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#40625
            for legal characters)

          o Its directory path relative to the root of the source tree is
            actually a legal package name (after converting its separators to
            dots)

          o Its package statement contains the legal package name (specified
            in the previous bullet)


       Processing of links - During a run, the Javadoc tool automatically adds
       cross-reference links to package, class and member names that are being
       documented as part of that run. Links appear in several places:

          o Declarations (return types, argument types, field types)

          o "See Also" sections generated from @see tags

          o In-line text generated from {@link} tags

          o Exception names generated from @throws tags

          o "Specified by" links to members in interfaces and "Overrides"
            links to members in classes

          o Summary tables listing packages, classes and members

          o Package and class inheritance trees

          o The index


       You can add hyperlinks to existing text for classes not included on the
       command line (but generated separately) by way of the -link and
       -linkoffline options.

       Other processing details - The Javadoc tool produces one complete
       document each time it is run; it cannot do incremental builds -- that
       is, it cannot modify or directly incorporate results from previous runs
       of the Javadoc tool. However, it can link to results from other runs,
       as just mentioned.

       As implemented, the Javadoc tool requires and relies on the java
       compiler to do its job. The Javadoc tool calls part of javac to compile
       the declarations, ignoring the member implementation. It builds a rich
       internal representation of the classes, including the class hierarchy,
       and "use" relationships, then generates the HTML from that. The Javadoc
       tool also picks up user-supplied documentation from documentation
       comments in the source code.

       In fact, the Javadoc tool will run on .java source files that are pure
       stub files with no method bodies. This means you can write
       documentation comments and run the Javadoc tool in the earliest stages
       of design while creating the API, before writing the implementation.

       Relying on the compiler ensures that the HTML output corresponds
       exactly with the actual implementation, which may rely on implicit,
       rather than explicit, source code. For example, the Javadoc tool
       documents default constructors @
       http://java.sun.com/docs/books/jls/second_edition/html/names.doc.html#36154
       (section 8.6.7 of Java Language Specification) that are present in the
       .class files but not in the source code.

       In many cases, the Javadoc tool allows you to generate documentation
       for source files whose code is incomplete or erroneous. This is a
       benefit that enables you to generate documentation before all debugging
       and troubleshooting is done. For example, according to the Java
       Language Specification, a class that contains an abstract method should
       itself be declared abstract. The Javadoc tool does not check for this,
       and would proceed without a warning, whereas the javac compiler stops
       on this error. The Javadoc tool does do some primitive checking of doc
       comments. Use the DocCheck doclet to check the doc comments more
       thoroughly.

       When the Javadoc tool builds its internal structure for the
       documentation, it loads all referenced classes. Because of this, the
       Javadoc tool must be able to find all referenced classes, whether
       bootstrap classes, extensions, or user classes. For more about this,
       see How Classes Are Found. Generally speaking, classes you create must
       either be loaded as an extension or in the Javadoc tool's class path.

   Javadoc Doclets
       You can customize the content and format of the Javadoc tool's output
       by using doclets. The Javadoc tool has a default "built-in" doclet,
       called the standard doclet, that generates HTML-formatted API
       documentation. You can modify or subclass the standard doclet, or write
       your own doclet to generate HTML, XML, MIF, RTF or whatever output
       format you'd like. Information about doclets and their use is at the
       following locations:

          o Javadoc Doclets

          o The -doclet command-line option


       When a custom doclet is not specified with the -doclet command line
       option, the Javadoc tool will use the default standard doclet. The
       javadoc tool has several command line options that are available
       regardless of which doclet is being used. The standard doclet adds a
       supplementary set of command line options. Both sets of options are
       described below in the options section.

   Terminology
       The terms documentation comment, doc comment, main description, tag,
       block tag, and in-line tag are described at Documentation Comments.
       These other terms have specific meanings within the context of the
       Javadoc tool:

          generated document
             The document generated by the javadoc tool from the doc comments
             in Java source code. The default generated document is in HTML
             and is created by the standard doclet.

          name
             A name of a program element written in the Java Language -- that
             is, the name of a package, class, interface, field, constructor
             or method. A name can be fully-qualified, such as
             java.lang.String.equals(java.lang.Object), or
             partially-qualified, such as equals(Object).

          documented classes
             The classes and interfaces for which detailed documentation is
             generated during a javadoc run. To be documented, the source
             files must be available, their source filenames or package names
             must be passed into the javadoc command, and they must not be
             filtered out by their access modifier (public, protected,
             package-private or private). We also refer to these as the
             classes included in the javadoc output, or the included classes.

          included classes
             Classes and interfaces whose details are documented during a run
             of the Javadoc tool. Same as documented classes.

          excluded classes
             Classes and interfaces whose details are not documented during a
             run of the Javadoc tool.

          referenced classes
             The classes and interfaces that are explicitly referred to in the
             definition (implementation) or doc comments of the documented
             classes and interfaces. Examples of references include return
             type, parameter type, cast type, extended class, implemented
             interface, imported classes, classes used in method bodies, @see,
             {@link}, {@linkplain}, and {@inheritDoc} tags. (Notice this
             definition has changed since 1.3 @
             http://java.sun.com/j2se/1.3/docs/tooldocs/solaris/javadoc.html#referencedclasses.)
             When the Javadoc tool is run, it should load into memory all of
             the referenced classes in javadoc's bootclasspath and classpath.
             (The Javadoc tool prints a "Class not found" warning for
             referenced classes not found.) The Javadoc tool can derive enough
             information from the .class files to determine their existence
             and the fully-qualified names of their members.

          external referenced classes
             The referenced classes whose documentation is not being generated
             during a javadoc run. In other words, these classes are not
             passed into the Javadoc tool on the command line. Links in the
             generated documentation to those classes are said to be external
             references or external links. For example, if you run the Javadoc
             tool on only the java.awt package, then any class in java.lang,
             such as Object, is an external referenced class. External
             referenced classes can be linked to using the -link and
             -linkoffline options. An important property of an external
             referenced class is that its source comments are normally not
             available to the Javadoc run. In this case, these comments cannot
             be inherited.


SOURCE FILES
       The Javadoc tool will generate output originating from four different
       types of "source" files: Java language source files for classes
       (.java), package comment files, overview comment files, and
       miscellaneous unprocessed files. This section also covers test files
       and template files that can also be in the source tree, but which you
       want to be sure not to document.

   Class Source Code Files
       Each class or interface and its members can have their own
       documentation comments, contained in a .java file. For more details
       about these doc comments, see Documentation Comments.

   Package Comment Files
       Each package can have its own documentation comment, contained in its
       own "source" file, that the Javadoc tool will merge into the package
       summary page that it generates. You typically include in this comment
       any documentation that applies to the entire package.

       To create a package comment file, you have a choice of two files to
       place your comments:

          o package-info.java - Can contain a package declaration, package
            annotations, package comments and Javadoc tags. This file is new
            in JDK 5.0, and is preferred over package.html.

          o package.html - Can contain only package comments and Javadoc tags,
            no package annotations.


       A package may have a single package.html file or a single
       package-info.java file but not both. Place either file in the package
       directory in the source tree along with your .java files.

       package-info.java This file can contain a package comment of the
       following structure -- the comment is placed before the package
       declaration:

       File: java/applet/package-info.java

       Note that while the comment separators /** and /* must be present, the
       leading asterisks on the intermediate lines can be omitted.

       package.html - This file can contain a package comment of the following
       structure -- the comment is placed in the <body> element:

       File: java/applet/package.html

       Notice this is just a normal HTML file and does not include a package
       declaration. The content of the package comment file is written in
       HTML, like all other comments, with one exception: The documentation
       comment should not include the comment separators /** and */ or leading
       asterisks. When writing the comment, you should make the first sentence
       a summary about the package, and not put a title or any other text
       between <body> and the first sentence. You can include package tags; as
       with any documentation comment, all block tags must appear after the
       main description. If you add a @see tag in a package comment file, it
       must have a fully-qualified name. For more details, see the example of
       package.html @
       http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#packagecomments.

       Processing of package comment file - When the Javadoc tool runs, it
       will automatically look for the package comment file; if found, the
       Javadoc tool does the following:

          o Copies the comment for processing. (For package.html, copies all
            content between <body> and </body> HTML tags. You can include a
            <head> section to put a <title>, source file copyright statement,
            or other information, but none of these will appear in the
            generated documentation.)

          o Processes any package tags that are present.

          o Inserts the processed text at the bottom of the package summary
            page it generates, as shown in Package Summary.

          o Copies the first sentence of the package comment to the top of the
            package summary page. It also adds the package name and this first
            sentence to the list of packages on the overview page, as shown in
            Overview Summary. The end-of-sentence is determined by the same
            rules used for the end of the first sentence of class and member
            main descriptions.


   Overview Comment File
       Each application or set of packages that you are documenting can have
       its own overview documentation comment, kept in its own "source" file,
       that the Javadoc tool will merge into the overview page that it
       generates. You typically include in this comment any documentation that
       applies to the entire application or set of packages.

       To create an overview comment file, you can name the file anything you
       want, typically overview.html and place it anywhere, typically at the
       top level of the source tree. For example, if the source files for the
       java.applet package are contained in /home/user/src/java/applet
       directory, you could create an overview comment file at
       /home/user/src/overview.html.

       Notice you can have multiple overview comment files for the same set of
       source files, in case you want to run javadoc multiple times on
       different sets of packages. For example, you could run javadoc once
       with -private for internal documentation and again without that option
       for public documentation. In this case, you could describe the
       documentation as public or internal in the first sentence of each
       overview comment file.

       The content of the overview comment file is one big documentation
       comment, written in HTML, like the package comment file described
       previously. See that description for details. To re-iterate, when
       writing the comment, you should make the first sentence a summary about
       the application or set of packages, and not put a title or any other
       text between <body> and the first sentence. You can include overview
       tags; as with any documentation comment, all tags except in-line tags,
       such as {@link}, must appear after the main description. If you add a
       @see tag, it must have a fully-qualified name.

       When you run the Javadoc tool, you specify the overview comment file
       name with the -overview option. The file is then processed similar to
       that of a package comment file.

          o Copies all content between <body> and </body> tags for processing.

          o Processes any overview tags that are present.

          o Inserts the processed text at the bottom of the overview page it
            generates, as shown in Overview Summary.

          o Copies the first sentence of the overview comment to the top of
            the overview summary page.


   Miscellaneous Unprocessed Files
       You can also include in your source any miscellaneous files that you
       want the Javadoc tool to copy to the destination directory. These
       typically includes graphic files, example Java source (.java) and class
       (.class) files, and self-standing HTML files whose content would
       overwhelm the documentation comment of a normal Java source file.

       To include unprocessed files, put them in a directory called doc-files
       which can be a subdirectory of any package directory that contains
       source files. You can have one such subdirectory for each package. You
       might include images, example code, source files, .class files, applets
       and HTML files. For example, if you want to include the image of a
       button button.gif in the java.awt.Button class documentation, you place
       that file in the /home/user/src/java/awt/doc-files/ directory. Notice
       the doc-files directory should not be located at
       /home/user/src/java/doc-files because java is not a package -- that is,
       it does not directly contain any source files.

       All links to these unprocessed files must be hard-coded, because the
       Javadoc tool does not look at the files -- it simply copies the
       directory and all its contents to the destination. For example, the
       link in the Button.java doc comment might look like:

           /**
            * This button looks like this:
            * <img src="doc-files/Button.gif">
            */


   Test Files and Template Files
       Some developers have indicated they want to store test files and
       templates files in the source tree near their corresponding source
       files. That is, they would like to put them in the same directory, or a
       subdirectory, of those source files.

       If you run the Javadoc tool by explicitly passing in individual source
       filenames, you can deliberately omit test and templates files and
       prevent them from being processed. However, if you are passing in
       package names or wildcards, you need to follow certain rules to ensure
       these test files and templates files are not processed.

       Test files differ from template files in that the former are legal,
       compilable source files, while the latter are not, but may end with
       ".java".

       Test files - Often developers want to put compilable, runnable test
       files for a given package in the same directory as the source files for
       that package. But they want the test files to belong to a package other
       than the source file package, such as the unnamed package (so the test
       files have no package statement or a different package statement from
       the source). In this scenario, when the source is being documented by
       specifying its package name specified on the command line, the test
       files will cause warnings or errors. You need to put such test files in
       a subdirectory. For example, if you want to add test files for source
       files in com.package1, put them in a subdirectory that would be an
       invalid package name (because it contains a hyphen):

           com/package1/test-files/


       The test directory will be skipped by the Javadoc tool with no
       warnings.

       If your test files contain doc comments, you can set up a separate run
       of the Javadoc tool to produce documentation of the test files by
       passing in their test source filenames with wildcards, such as
       com/package1/test-files/*.java.

       Templates for source files - Template files have names that often end
       in ".java" and are not compilable. If you have a template for a source
       file that you want to keep in the source directory, you can name it
       with a dash (such as Buffer-Template.java), or any other illegal Java
       character, to prevent it from being processed. This relies on the fact
       that the Javadoc tool will only process source files whose name, when
       stripped of the ".java" suffix, is actually a legal class name (see
       Identifiers @
       http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html#40625).

GENERATED FILES
       By default, javadoc uses a standard doclet that generates
       HTML-formatted documentation. This doclet generates the following kinds
       of files (where each HTML "page" corresponds to a separate file). Note
       that javadoc generates files with two types of names: those named after
       classes/interfaces, and those that are not (such as
       package-summary.html). Files in the latter group contain hyphens to
       prevent filename conflicts with those in the former group.

       Basic Content Pages

          o One class or interface page (classname.html) for each class or
            interface it is documenting.

          o One package page (package-summary.html) for each package it is
            documenting. The Javadoc tool will include any HTML text provided
            in a file named package.html or package-info.java in the package
            directory of the source tree.

          o One overview page (overview-summary.html) for the entire set of
            packages. This is the front page of the generated document. The
            Javadoc tool will include any HTML text provided in a file
            specified with the -overview option. Note that this file is
            created only if you pass into javadoc two or more package names.
            For further explanation, see HTML Frames.)


       Cross-Reference Pages

          o One class hierarchy page for the entire set of packages
            (overview-tree.html). To view this, click on "Overview" in the
            navigation bar, then click on "Tree".

          o One class hierarchy page for each package (package-tree.html) To
            view this, go to a particular package, class or interface page;
            click "Tree" to display the hierarchy for that package.

          o One "use" page for each package (package-use.html) and a separate
            one for each class and interface (class-use/classname.html). This
            page describes what packages, classes, methods, constructors and
            fields use any part of the given class, interface or package.
            Given a class or interface A, its "use" page includes subclasses
            of A, fields declared as A, methods that return A, and methods and
            constructors with parameters of type A. You can access this page
            by first going to the package, class or interface, then clicking
            on the "Use" link in the navigation bar.

          o A deprecated API page (deprecated-list.html) listing all
            deprecated names. (A deprecated name is not recommended for use,
            generally due to improvements, and a replacement name is usually
            given. Deprecated APIs may be removed in future implementations.)

          o A constant field values page (constant-values.html) for the values
            of static fields.

          o A serialized form page (serialized-form.html) for information
            about serializable and externalizable classes. Each such class has
            a description of its serialization fields and methods. This
            information is of interest to re-implementors, not to developers
            using the API. While there is no link in the navigation bar, you
            can get to this information by going to any serialized class and
            clicking "Serialized Form" in the "See also" section of the class
            comment. The standard doclet automatically generates a serialized
            form page: any class (public or non-public) that implements
            Serializable is included, along with readObject and writeObject
            methods, the fields that are serialized, and the doc comments from
            the @serial, @serialField, and @serialData tags. Public
            serializable classes can be excluded by marking them (or their
            package) with @serial exclude, and package-private serializable
            classes can be included by marking them (or their package) with
            @serial include. As of 1.4, you can generate the complete
            serialized form for public and private classes by running javadoc
            without specifying the -private option.

          o An index (index-*.html) of all class, interface, constructor,
            field and method names, alphabetically arranged. This is
            internationalized for Unicode and can be generated as a single
            file or as a separate file for each starting character (such as
            A-Z for English).


       Support Files

          o A help page (help-doc.html) that describes the navigation bar and
            the above pages. You can provide your own custom help file to
            override the default using -helpfile.

          o One index.html file which creates the HTML frames for display.
            This is the file you load to display the front page with frames.
            This file itself contains no text content.

          o Several frame files (*-frame.html) containing lists of packages,
            classes and interfaces, used when HTML frames are being displayed.

          o A package list file (package-list), used by the -link and
            -linkoffline options. This is a text file, not HTML, and is not
            reachable through any links.

          o A style sheet file (stylesheet.css) that controls a limited amount
            of color, font family, font size, font style and positioning on
            the generated pages.

          o A doc-files directory that holds any image, example, source code
            or other files that you want copied to the destination directory.
            These files are not processed by the Javadoc tool in any manner --
            that is, any javadoc tags in them will be ignored. This directory
            is not generated unless it exists in the source tree.


       HTML Frames

       The Javadoc tool will generate either two or three HTML frames, as
       shown in the figure below. It creates the minimum necessary number of
       frames by omitting the list of packages if there is only one package
       (or no packages). That is, when you pass a single package name or
       source files (*.java) belonging to a single package as arguments into
       the javadoc command, it will create only one frame (C) in the left-hand
       column -- the list of classes. When you pass into javadoc two or more
       package names, it creates a third frame (P) listing all packages, as
       well as an overview page (Detail). This overview page has the filename
       overview-summary.html. Thus, this file is created only if you pass in
       two or more package names. You can bypass frames by clicking on the "No
       Frames" link or entering at overview-summary.html.

       If you are unfamiliar with HTML frames, you should be aware that frames
       can have focus for printing and scrolling. To give a frame focus, click
       on it. Then on many browsers the arrow keys and page keys will scroll
       that frame, and the print menu command will print it.

                     ------------                  ------------
                     |C| Detail |                  |P| Detail |
                     | |        |                  | |        |
                     | |        |                  |-|        |
                     | |        |                  |C|        |
                     | |        |                  | |        |
                     | |        |                  | |        |
                     ------------                  ------------
                    javadoc *.java           javadoc java.lang java.awt


       Load one of the following two files as the starting page depending on
       whether you want HTML frames or not:

          o index.html (for frames)

          o overview-summary.html (for no frames)


       Generated File Structure

       The generated class and interface files are organized in the same
       directory hierarchy that Java source files and class files are
       organized. This structure is one directory per subpackage.

       For example, the document generated for the class java.applet.Applet
       class would be located at java/applet/Applet.html. The file structure
       for the java.applet package follows, given that the destination
       directory is named apidocs. All files that contain the word "frame"
       appear in the upper-left or lower-left frames, as noted. All other HTML
       files appear in the right-hand frame.

          NOTE - Directories are shown in bold. The asterisks (*) indicate the
          files and directories that are omitted when the arguments to javadoc
          are source filenames (*.java) rather than package names. Also when
          arguments are source filenames, package-list is created but is
          empty. The doc-files directory will not be created in the
          destination unless it exists in the source tree.

   a name="generatedapideclarations"/> Generated API Declarations
       The Javadoc tool generates a declaration at the start of each class,
       interface, field, constructor, and method description for that API
       item. For example, the declaration for the Boolean class is:

       public final class Boolean
       extends Object
       implements Serializable

       and the declaration for the Boolean.valueOfmethod is:

       public static Boolean valueOf(String s)

       The Javadoc tool can include the modifiers public, protected, private,
       abstract, final, static, transient, and volatile, but not synchronized
       or native. These last two modifiers are considered implementation
       detail and not part of the API specification.

       Rather than relying on the keyword synchronized, APIs should document
       their concurrency semantics in the comment's main description, as in "a
       single Enumeration cannot be used by multiple threads concurrently".
       The document should not describe how to achieve these semantics. As
       another example, while Hashtable should be thread-safe, there's no
       reason to specify that we achieve this by synchronizing all of its
       exported methods. We should reserve the right to synchronize internally
       at the bucket level, thus offering higher concurrency.

DOCUMENTATION COMMENTS
       The original "Documentation Comment Specification" can be found under
       related documentation.

   Commenting the Source Code
       You can include documentation comments ("doc comments") in the source
       code, ahead of declarations for any class, interface, method,
       constructor, or field. You can also create doc comments for each
       package and another one for the overview, though their syntax is
       slightly different. Doc comments are also known informally as "Javadoc
       comments" (but this term violates its trademark usage). A doc comment
       consists of the characters between the characters /** that begin the
       comment and the characters */ that end it. Leading asterisks are
       allowed on each line and are described further below. The text in a
       comment can continue onto multiple lines.

       /**
        * This is the typical format of a simple documentation comment
        * that spans two lines.
        */


       To save space you can put a comment on one line:

       /** This comment takes up only one line. */


       Placement of comments - Documentation comments are recognized only when
       placed immediately before class, interface, constructor, method, or
       field declarations -- see the class example, method example, and field
       example. Documentation comments placed in the body of a method are
       ignored. Only one documentation comment per declaration statement is
       recognized by the Javadoc tool.

       A common mistake is to put an import statement between the class
       comment and the class declaration. Avoid this, as the Javadoc tool will
       ignore the class comment.

          /**
           * This is the class comment for the class Whatever.
           */

           import com.sun;   // MISTAKE - Important not to put import statement here

           public class Whatever {
           }


       A doc comment is composed of a main description followed by a tag
       section - The main description begins after the starting delimiter /**
       and continues until the tag section. The tag section starts with the
       first block tag, which is defined by the first @ character that begins
       a line (ignoring leading asterisks, white space, and leading separator
       /**). It is possible to have a comment with only a tag section and no
       main description. The main description cannot continue after the tag
       section begins. The argument to a tag can span multiple lines. There
       can be any number of tags -- some types of tags can be repeated while
       others cannot. For example, this @see starts the tag section:

       /**
        * This sentence would hold the main description for this doc comment.
        * @see java.lang.Object
        */


       Block tags and in-line tags - A tag is a special keyword within a doc
       comment that the Javadoc tool can process. There are two kinds of tags:
       block tags, which appear as @tag (also known as "standalone tags"), and
       in-line tags, which appear within curly braces, as {@tag}. To be
       interpreted, a block tag must appear at the beginning of a line,
       ignoring leading asterisks, white space, and separator (/**). This
       means you can use the @ character elsewhere in the text and it will not
       be interpreted as the start of a tag. If you want to start a line with
       the @ character and not have it be interpreted, use the HTML entity
       &#064;. Each block tag has associated text, which includes any text
       following the tag up to, but not including, either the next tag, or the
       end of the doc comment. This associated text can span multiple lines.
       An in-line tag is allowed and interpreted anywhere that text is
       allowed. The following example contains the block tag @deprecated and
       in-line tag {@link}.

       /**
        * @deprecated  As of JDK 1.1, replaced by {@link #setBounds(int,int,int,int)}
        */


       Comments are written in HTML - The text must be written in HTML, in
       that they should use HTML entities and can use HTML tags. You can use
       whichever version of HTML your browser supports; we have written the
       standard doclet to generate HTML 3.2-compliant code elsewhere (outside
       of the documentation comments) with the inclusion of cascading style
       sheets and frames. (We preface each generated file with "HTML 4.0"
       because of the frame sets.)

       For example, entities for the less-than (<) and greater-than (>)
       symbols should be written < and >. Likewise, the ampersand (&) should
       be written &. The bold HTML tag <b> is shown in the following example.

       Here is a doc comment:

       /**
        * This is a <b>doc</b> comment.
        * @see java.lang.Object
        */


       Leading asterisks - When javadoc parses a doc comment, leading asterisk
       (*) characters on each line are discarded; blanks and tabs preceding
       the initial asterisk (*) characters are also discarded. Starting with
       1.4, if you omit the leading asterisk on a line, the leading white
       space is no longer removed. This enables you to paste code examples
       directly into a doc comment inside a <PRE> tag, and its indentation
       will be honored. Spaces are generally interpreted by browsers more
       uniformly than tabs. Indentation is relative to the left margin (rather
       than the separator /** or <PRE> tag).

       First sentence - The first sentence of each doc comment should be a
       summary sentence, containing a concise but complete description of the
       declared entity. This sentence ends at the first period that is
       followed by a blank, tab, or line terminator, or at the first block
       tag. The Javadoc tool copies this first sentence to the member summary
       at the top of the HTML page.

       Declaration with multiple fields - Java allows declaring multiple
       fields in a single statement, but this statement can have only one
       documentation comment, which is copied for all fields. Therefore if you
       want individual documentation comments for each field, you must declare
       each field in a separate statement. For example, the following
       documentation comment doesn't make sense written as a single
       declaration and would be better handled as two declarations:

          /**
           * The horizontal and vertical distances of point (x,y)
           */
          public int x, y;      // Avoid this


       The Javadoc tool generates the following documentation from the above
       code:

          public int x


             The horizontal and vertical distances of point (x,y)


          public int y


             The horizontal and vertical distances of point (x,y)


       Use header tags carefully - When writing documentation comments for
       members, it's best not to use HTML heading tags such as <H1> and <H2>,
       because the Javadoc tool creates an entire structured document and
       these structural tags might interfere with the formatting of the
       generated document. However, it is fine to use these headings in class
       and package comments to provide your own structure.

   Automatic Copying of Method Comments
       The Javadoc tool has the ability to copy or "inherit" method comments
       in classes and interfaces under the following two circumstances.
       Constructors, fields and nested classes do not inherit doc comments.

          o Automatically inherit comment to fill in missing text - When a
            main description, or @return, @param or @throws  tag is missing
            from a method comment, the Javadoc tool copies the corresponding
            main description or tag comment from the method it overrides or
            implements (if any), according to the algorithm below.

          More specifically, when a @param tag for a particular parameter is
          missing, then the comment for that parameter is copied from the
          method further up the inheritance hierarchy. When a @throws tag for
          a particular exception is missing, the @throws tag is copied only if
          that exception is declared.

          This behavior contrasts with version 1.3 and earlier, where the
          presence of any main description or tag would prevent all comments
          from being inherited.

          o Explicitly inherit comment with {@inheritDoc} tag - Insert the
            inline tag {@inheritDoc} in a method main description or @return,
            @param or @throws tag comment -- the corresponding inherited main
            description or tag comment is copied into that spot.


       The source file for the inherited method need only be on the path
       specified by -sourcepath for the doc comment to actually be available
       to copy. Neither the class nor its package needs to be passed in on the
       command line. This contrasts with 1.3.x and earlier releases, where the
       class had to be a documented class

       Inherit from classes and interfaces - Inheriting of comments occurs in
       all three possible cases of inheritance from classes and interfaces:

          o When a method in a class overrides a method in a superclass

          o When a method in an interface overrides a method in a
            superinterface

          o When a method in a class implements a method in an interface


       In the first two cases, for method overrides, the Javadoc tool
       generates a subheading "Overrides" in the documentation for the
       overriding method, with a link to the method it is overriding, whether
       or not the comment is inherited.

       In the third case, when a method in a given class implements a method
       in an interface, the Javadoc tool generates a subheading "Specified by"
       in the documentation for the overriding method, with a link to the
       method it is implementing. This happens whether or not the comment is
       inherited.

       Algorithm for Inheriting Method Comments - If a method does not have a
       doc comment, or has an {@inheritDoc} tag, the Javadoc tool searches for
       an applicable comment using the following algorithm, which is designed
       to find the most specific applicable doc comment, giving preference to
       interfaces over superclasses:

          1. Look in each directly implemented (or extended) interface in the
             order they appear following the word implements (or extends) in
             the method declaration. Use the first doc comment found for this
             method.

          2. If step 1 failed to find a doc comment, recursively apply this
             entire algorithm to each directly implemented (or extended)
             interface, in the same order they were examined in step 1.

          3. If step 2 failed to find a doc comment and this is a class other
             than Object (not an interface):

             a. If the superclass has a doc comment for this method, use it.

             b. If step 3a failed to find a doc comment, recursively apply
                this entire algorithm to the superclass.


JAVADOC TAGS
       The Javadoc tool parses special tags when they are embedded within a
       Java doc comment. These doc tags enable you to autogenerate a complete,
       well-formatted API from your source code. The tags start with an "at"
       sign (@) and are case-sensitive -- they must be typed with the
       uppercase and lowercase letters as shown. A tag must start at the
       beginning of a line (after any leading spaces and an optional asterisk)
       or it is treated as normal text. By convention, tags with the same name
       are grouped together. For example, put all @see tags together.

       Tags come in two types:

          o Block tags - Can be placed only in the tag section that follows
            the main description. Block tags are of the form: @tag.

          o Inline tags - Can be placed anywhere in the main description or in
            the comments for block tags. Inline tags are denoted by curly
            braces: {@tag}.


       For information about tags we might introduce in future releases, see
       Proposed Tags @
       http://java.sun.com/j2se/javadoc/proposed-tags.html.

       The current tags are:

          For custom tags, see the -tag option.

          @author  name-text
             Adds an "Author" entry with the specified name-text to the
             generated docs when the -author option is used. A doc comment may
             contain multiple @author tags. You can specify one name per
             @author tag or multiple names per tag. In the former case, the
             Javadoc tool inserts a comma (,) and space between names. In the
             latter case, the entire text is simply copied to the generated
             document without being parsed. Therefore, you can use multiple
             names per line if you want a localized name separator other than
             comma.

          For more details, see Where Tags Can Be Used and writing @author
          tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@author.

          @deprecated  deprecated-text


             Note: Starting with JDK 5.0, you can deprecate a program element
             using the @Deprecated annotation.

          Adds a comment indicating that this API should no longer be used
          (even though it may continue to work). The Javadoc tool moves the
          deprecated-text ahead of the main description, placing it in italics
          and preceding it with a bold warning: "Deprecated". This tag is
          valid in all doc comments: overview, package, class, interface,
          constructor, method and field.

          The first sentence of deprecated-text should at least tell the user
          when the API was deprecated and what to use as a replacement. The
          Javadoc tool copies just the first sentence to the summary section
          and index. Subsequent sentences can also explain why it has been
          deprecated. You should include a {@link} tag (for Javadoc 1.2 or
          later) that points to the replacement API:

          For more details, see writing @deprecated tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@deprecated.

             o For Javadoc 1.2 and later, use a {@link} tag. This creates the
               link in-line, where you want it. For example:
               /**
                * @deprecated  As of JDK 1.1, replaced by {@link #setBounds(int,int,int,int)}
                */

             o For Javadoc 1.1, the standard format is to create a @see tag
               (which cannot be in-line) for each @deprecated tag.

          For more about deprecation, see The @deprecated tag.

          {@code  text}
             Equivalent to <code>{@literal}</code>.

          Displays text in code font without interpreting the text as HTML
          markup or nested javadoc tags. This enables you to use regular angle
          brackets (< and >) instead of the HTML entities (< and >) in doc
          comments, such as in parameter types (<Object>), inequalities (3 <
          4), or arrows (<-). For example, the doc comment text:
               {@code A<B>C}
          displays in the generated HTML page unchanged, as:
               A<B>C
          The noteworthy point is that the <B> is not interpreted as bold and
          is in code font.

          If you want the same functionality without the code font, use
          {@literal}.

          {@docRoot}
             Represents the relative path to the generated document's
             (destination) root directory from any generated page. It is
             useful when you want to include a file, such as a copyright page
             or company logo, that you want to reference from all generated
             pages. Linking to the copyright page from the bottom of each page
             is common.

          This {@docRoot} tag can be used both on the command line and in a
          doc comment: This tag is valid in all doc comments: overview,
          package, class, interface, constructor, method and field, including
          the text portion of any tag (such as @return, @param and
          @deprecated).

             1. On the command line, where the header/footer/bottom are
                defined:
                   javadoc -bottom '<a href="{@docRoot}/copyright.html">Copyright</a>'
                NOTE - When using {@docRoot} this way in a make file, some
                makefile programs require special escaping for the brace {}
                characters. For example, the Inprise MAKE version 5.2 running
                on Windows requires double braces: {{@docRoot}}. It also
                requires double (rather than single) quotes to enclose
                arguments to options such as -bottom (with the quotes around
                the href argument omitted).

             2. In a doc comment:
                   /**
                    * See the <a href="{@docRoot}/copyright.html">Copyright</a>.
                    */
          The reason this tag is needed is because the generated docs are in
          hierarchical directories, as deep as the number of subpackages. This
          expression:
            <a href="{@docRoot}/copyright.html">
          would resolve to:
            <a href="../../copyright.html">      for java/lang/Object.java
          and
            <a href="../../../copyright.html">   for java/lang/ref/Reference.java

          @exception  class-name  description
             The @exception tag is a synonym for @throws.

          {@inheritDoc}
             Inherits (copies) documentation from the "nearest" inheritable
             class or implementable interface into the current doc comment at
             this tag's location. This allows you to write more general
             comments higher up the inheritance tree, and to write around the
             copied text.

          This tag is valid only in these places in a doc comment:

             o In the main description block of a method. In this case, the
               main description is copied from a class or interface up the
               hierarchy.

             o In the text arguments of the @return, @param and @throws tags
               of a method. In this case, the tag text is copied from the
               corresponding tag up the hierarchy.

          See Automatic Copying of Method Comments for a more precise
          description of how comments are found in the inheritance hierarchy.
          Note that if this tag is missing, the comment is or is not
          automatically inherited according to rules described in that
          section.

          {@link  package.class#member  label}
             Inserts an in-line link with visible text label that points to
             the documentation for the specified package, class or member name
             of a referenced class. This tag is valid in all doc comments:
             overview, package, class, interface, constructor, method and
             field, including the text portion of any tag (such as @return,
             @param and @deprecated).

          This tag is very simliar to @see -- both require the same references
          and accept exactly the same syntax for package.class#member and
          label. The main difference is that {@link} generates an in-line link
          rather than placing the link in the "See Also" section. Also, the
          {@link} tag begins and ends with curly braces to separate it from
          the rest of the in-line text. If you need to use "}" inside the
          label, use the HTML entity notation &#125;

          There is no limit to the number of {@link} tags allowed in a
          sentence. You can use this tag in the main description part of any
          documentation comment or in the text portion of any tag (such as
          @deprecated, @return or @param).

          For example, here is a comment that refers to the
          getComponentAt(int, int) method:
          Use the {@link #getComponentAt(int, int) getComponentAt} method.
          From this, the standard doclet would generate the following HTML
          (assuming it refers to another class in the same package):
          Use the <a href="Component.html#getComponentAt(int, int)">getComponentAt</a> method.
          Which appears on the web page as:
          Use the getComponentAt method.
          You can extend {@link} to link to classes not being documented by
          using the -link option.

          For more details, see writing {@link} tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#{@link}.

          {@linkplain  package.class#member  label}
             Identical to {@link}, except the link's label is displayed in
             plain text than code font. Useful when the label is plain text.
             Example:
                  Refer to {@linkplain add() the overridden method}.
             This would display as:

             Refer to the overridden method.

          {@literal  text}
             Displays text without interpreting the text as HTML markup or
             nested javadoc tags. This enables you to use regular angle
             brackets (< and >) instead of the HTML entities (< and >) in doc
             comments, such as in parameter types (<Object>), inequalities (3
             < 4), or arrows (<-). For example, the doc comment text:
                  {@literal A<B>C}
             displays unchanged in the generated HTML page in your browser,
             as:

               A<B>C  The noteworthy point is that the <B> is not interpreted
          as bold (and it is not in code font).

          If you want the same functionality but with the text in code font,
          use {@code}.

          @param  parameter-name description
             Adds a parameter with the specified parameter-name followed by
             the specified description to the "Parameters" section. When
             writing the doc comment, you may continue the description onto
             multiple lines. This tag is valid only in a doc comment for a
             method, constructor or class.

          The parameter-name can be the name of a parameter in a method or
          constructor, or the name of a type parameter of a class, method or
          constructor. Use angle brackets around this parameter name to
          specify the use of a type parameter.

          Example of a type parameter of a class:
               /**
                * @param <E> Type of element stored in a list
                */
               public interface List<E> extends Collection<E> {
               }

          Example of a type parameter of a method:
               /**
                * @param string  the string to be converted
                * @param type    the type to convert the string to
                * @param <T>     the type of the element
                * @param <V>     the value of the element
                */
               <T, V extends T> V convert(String string, Class<T> type) {
               }
          For more details, see writing @param tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@param.

          @return  description
             Adds a "Returns" section with the description text. This text
             should describe the return type and permissible range of values.
             This tag is valid only in a doc comment for a method.

          For more details, see writing @return tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@return.

          @see  reference
             Adds a "See Also" heading with a link or text entry that points
             to reference. A doc comment may contain any number of @see tags,
             which are all grouped under the same heading. The @see tag has
             three variations; the third form below is the most common. This
             tag is valid in any doc comment: overview, package, class,
             interface, constructor, method or field. For inserting an in-line
             link within a sentence to a package, class or member, see
             {@link}.

             @see "string"
                Adds a text entry for string. No link is generated. The string
                is a book or other reference to information not available by
                URL. The Javadoc tool distinguishes this from the previous
                cases by looking for a double-quote (") as the first
                character. For example:
                     @see "The Java Programming Language"
                This generates text such as:

                   See Also:
                      "The Java Programming Language"


             @see <a href="URL#value">label</a>
                Adds a link as defined by URL#value. The URL#value is a
                relative or absolute URL. The Javadoc tool distinguishes this
                from other cases by looking for a less-than symbol (<) as the
                first character. For example:
                     @see <a href="spec.html#section">Java Spec</a>
                This generates a link such as:

                   See Also:
                      Java Spec


             @see  package.class#member  label
                Adds a link, with visible text label, that points to the
                documentation for the specified name in the Java Language that
                is referenced. The label is optional; if omitted, the name
                appears instead as the visible text, suitably shortened -- see
                How a name is displayed. Use -noqualifier to globally remove
                the package name from this visible text. Use the label when
                you want the visible text to be different from the
                auto-generated visible text.

             Only in version 1.2, just the name but not the label would
             automatically appear in <code> HTML tags, Starting with 1.2.2,
             the <code> is always included around the visible text, whether or
             not a label is used.

                o package.class#member is any valid program element name that
                  is referenced -- a package, class, interface, constructor,
                  method or field name -- except that the character ahead of
                  the member name should be a hash character (#). The class
                  represents any top-level or nested class or interface. The
                  member represents any constructor, method or field (not a
                  nested class or interface). If this name is in the
                  documented classes, the Javadoc tool will automatically
                  create a link to it. To create links to external referenced
                  classes, use the -link option. Use either of the other two
                  @see forms for referring to documentation of a name that
                  does not belong to a referenced class. This argument is
                  described at greater length below under Specifying a Name.

                o label is optional text that is visible as the link's label.
                  The label can contain whitespace. If label is omitted, then
                  package.class.member will appear, suitably shortened
                  relative to the current class and package -- see How a name
                  is displayed.

                o A space is the delimiter between package.class#member and
                  label. A space inside parentheses does not indicate the
                  start of a label, so spaces may be used between parameters
                  in a method.

             Example - In this example, an @see tag (in the Character class)
             refers to the equals method in the String class. The tag includes
             both arguments: the name "String#equals(Object)" and the label
             "equals".
                 /**
                  * @see String#equals(Object) equals
                  */
             The standard doclet produces HTML something like this:


                <dl>
                <dt><b>See Also:</b>
                <dd><a href="../../java/lang/String#equals(java.lang.Object)"><code>equals<code></a>
                </dl>
             Which looks something like this in a browser, where the label is
             the visible link text:


                   See Also:
                      equals


             Specifying a name - This package.class#member name can be either
             fully-qualified, such as java.lang.String#toUpperCase() or not,
             such as String#toUpperCase() or #toUpperCase(). If less than
             fully-qualified, the Javadoc tool uses the normal Java compiler
             search order to find it, further described below in Search order
             for @see. The name can contain whitespace within parentheses,
             such as between method arguments.

             Of course the advantage of providing shorter,
             "partially-qualified" names is that they are shorter to type and
             there is less clutter in the source code. The following table
             shows the different forms of the name, where Class can be a class
             or interface, Type can be a class, interface, array, or
             primitive, and method can be a method or constructor.

             The following notes apply to the above table:

                o The first set of forms (with no class or package) will cause
                  the Javadoc tool to search only through the current class's
                  hierarchy. It will find a member of the current class or
                  interface, one of its superclasses or superinterfaces, or
                  one of its enclosing classes or interfaces (search steps
                  1-3). It will not search the rest of the current package or
                  other packages (search steps 4-5).

                o If any method or constructor is entered as a name with no
                  parentheses, such as getValue, and if there is no field with
                  the same name, the Javadoc tool will correctly create a link
                  to it, but will print a warning message reminding you to add
                  the parentheses and arguments. If this method is overloaded,
                  the Javadoc tool will link to the first method its search
                  encounters, which is unspecified.

                o Nested classes must be specified as outer.inner, not simply
                  inner, for all forms.

                o As stated, the hash character (#), rather than a dot (.)
                  separates a member from its class. This enables the Javadoc
                  tool to resolve ambiguities, since the dot also separates
                  classes, nested classes, packages, and subpackages. However,
                  the Javadoc tool is generally lenient and will properly
                  parse a dot if you know there is no ambiguity, though it
                  will print a warning.

             Search order for @see - the Javadoc tool will process a @see tag
             that appears in a source file (.java), package file (package.html
             or package-info.java) or overview file (overview.html). In the
             latter two files, you must fully-qualify the name you supply with
             @see. In a source file, you can specify a name that is
             fully-qualified or partially-qualified.

             When the Javadoc tool encounters a @see tag in a .java file that
             is not fully qualified, it searches for the specified name in the
             same order as the Java compiler would (except the Javadoc tool
             will not detect certain namespace ambiguities, since it assumes
             the source code is free of these errors). This search order is
             formally defined in Chapter 6, "Names" of the Java Language
             Specification, Second Edition. The Javadoc tool searches for that
             name through all related and imported classes and packages. In
             particular, it searches in this order:

                1. the current class or interface

                2. any enclosing classes and interfaces, searching closest
                   first

                3. any superclasses and superinterfaces, searching closest
                   first

                4. the current package

                5. any imported packages, classes and interfaces, searching in
                   the order of the import statement

             The Javadoc tool continues to search recursively through steps
             1-3 for each class it encounters until it finds a match. That is,
             after it searches through the current class and its enclosing
             class E, it will search through E's superclasses before E's
             enclosing classes.  In steps 4 and 5, the Javadoc tool does not
             search classes or interfaces within a package in any specified
             order (that order depends on the particular compiler). In step 5,
             the Javadoc tool looks in java.lang, since that is automatically
             imported by all programs.

             The Javadoc tool does not necessarily look in subclasses, nor
             will it look in other packages even if their documentation is
             being generated in the same run. For example, if the @see tag is
             in the java.awt.event.KeyEvent class and refers to a name in the
             java.awt package, javadoc does not look in that package unless
             that class imports it.

             How a name is displayed - If label is omitted, then
             package.class.member appears. In general, it is suitably
             shortened relative to the current class and package. By
             "shortened", we mean the Javadoc tool displays only the minimum
             name necessary. For example, if the String.toUpperCase() method
             contains references to a member of the same class and to a member
             of a different class, the class name is displayed only in the
             latter case, as shown in the following table.

             Use -noqualifier to globally remove the package names.

             Examples of @see
             The comment to the right shows how the name would be displayed if
             the @see tag is in a class in another package, such as
             java.applet.Applet.

             using the -link option.

          @serial  field-description | include | exclude
             Used in the doc comment for a default serializable field.

          An optional field-description should explain the meaning of the
          field and list the acceptable values. If needed, the description can
          span multiple lines. The standard doclet adds this information to
          the serialized form page.

          If a serializable field was added to a class some time after the
          class was made serializable, a statement should be added to its main
          description to identify at which version it was added.

          The include and exclude arguments identify whether a class or
          package should be included or excluded from the serialized form
          page. They work as follows:

             o A public or protected class that implements Serializable is
               included unless that class (or its package) is marked @serial
               exclude.

             o A private or package-private class that implements Serializable
               is excluded unless that class (or its package) is marked
               @serial include.

          Examples: The javax.swing package is marked @serial exclude (in
          package.html or package-info.java). The public class
          java.security.BasicPermission is marked @serial exclude. The
          package-private class java.util.PropertyPermissionCollection is
          marked @serial include.

          The tag @serial at a class level overrides @serial at a package
          level.

          For more information about how to use these tags, along with an
          example, see "Documenting Serializable Fields and Data for a Class,"
          Section 1.6 of the Java Object Serialization Specification. Also see
          the Serialization FAQ @
          http://java.sun.com/products/jdk/serialization/faq/#javadoc_warn_missing,
          which covers common questions, such as "Why do I see javadoc
          warnings stating that I am missing @serial tags for private fields
          if I am not running javadoc with the -private switch?". Also see
          Sun's criteria @
          http://java.sun.com/j2se/javadoc/writingapispecs/serialized-criteria.html
          for including classes in the serialized form specification.

          @serialField  field-name  field-type  field-description
             Documents an ObjectStreamField component of a Serializable
             class's serialPersistentFields member. One @serialField tag
             should be used for each ObjectStreamField component.

          @serialData  data-description
             The data-description documents the types and order of data in the
             serialized form. Specifically, this data includes the optional
             data written by the writeObject method and all data (including
             base classes) written by the Externalizable.writeExternal method.

          The @serialData tag can be used in the doc comment for the
          writeObject, readObject, writeExternal, readExternal, writeReplace,
          and readResolve methods.

          @since  since-text
             Adds a "Since" heading with the specified since-text to the
             generated documentation. The text has no special internal
             structure. This tag is valid in any doc comment: overview,
             package, class, interface, constructor, method or field. This tag
             means that this change or feature has existed since the software
             release specified by the since-text. For example:
                 @since 1.5
             For source code in the Java platform, this tag indicates the
             version of the Java platform API specification (not necessarily
             when it was added to the reference implementation). Multiple
             @since tags are allowed and are treated like multiple @author
             tags. You could use multiple tags if the prgram element is used
             by more than one API.

          @throws  class-name  description
             The @throws and @exception tags are synonyms. Adds a "Throws"
             subheading to the generated documentation, with the class-name
             and description text. The class-name is the name of the exception
             that may be thrown by the method. This tag is valid only in the
             doc comment for a method or constructor. If this class is not
             fully-specified, the Javadoc tool uses the search order to look
             up this class. Multiple @throws tags can be used in a given doc
             comment for the same or different exceptions.

          To ensure that all checked exceptions are documented, if a @throws
          tag does not exist for an exception in the throws clause, the
          Javadoc tool automatically adds that exception to the HTML output
          (with no description) as if it were documented with @throws tag.

          The @throws documentation is copied from an overridden method to a
          subclass only when the exception is explicitly declared in the
          overridden method. The same is true for copying from an interface
          method to an implementing method. You can use {@inheritDoc} to force
          @throws to inherit documentation.

          For more details, see writing @throws tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@exception.

          {@value  package.class#field}
             When {@value} is used (without any argument) in the doc comment
             of a static field, it displays the value of that constant:
                 /**
                  * The value of this constant is {@value}.
                  */
                 public static final String SCRIPT_START = "<script>"
             When used with argument package.class#field in any doc comment,
             it displays the value of the specified constant:
                 /**
                  * Evaluates the script starting with {@value #SCRIPT_START}.
                  */
                 public String evalScript(String script) {
                 }
             The argument package.class#field takes a form identical to that
             of the @see argument, except that the member must be a static
             field.

          These values of these constants are also displayed on the Constant
          Field Values page.

          @version  version-text
             Adds a "Version" subheading with the specified version-text to
             the generated docs when the -version option is used. This tag is
             intended to hold the current version number of the software that
             this code is part of (as opposed to @since, which holds the
             version number where this code was introduced). The version-text
             has no special internal structure. To see where the version tag
             can be used, see Where Tags Can Be Used.

          A doc comment may contain multiple @version tags. If it makes sense,
          you can specify one version number per @version tag or multiple
          version numbers per tag. In the former case, the Javadoc tool
          inserts a comma (,) and space between names. In the latter case, the
          entire text is simply copied to the generated document without being
          parsed. Therefore, you can use multiple names per line if you want a
          localized name separator other than comma.

          For more details, see writing @version tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#@version.

   Where Tags Can Be Used
       The following sections describe where the tags can be used. Note that
       these tags can be used in all doc comments: @see, @since, @deprecated,
       {@link}, {@linkplain}, and {@docroot}.

   Overview Documentation Tags
       Overview tags are tags that can appear in the documentation comment for
       the overview page (which resides in the source file typically named
       overview.html). Like in any other documentation comments, these tags
       must appear after the main description.

       NOTE - The {@link} tag has a bug in overview documents in version 1.2
       -- the text appears properly but has no link. The {@docRoot} tag does
       not currently work in overview documents.

   Package Documentation Tags
       Package tags are tags that can appear in the documentation comment for
       a package (which resides in the source file named package.html or
       package-info.java). The @serial tag can only be used here with the
       include or exclude argument.

   Class and Interface Documentation Tags
       The following are tags that can appear in the documentation comment for
       a class or interface. The @serial tag can only be used here with the
       include or exclude argument.

       An example of a class comment:

       /**
        * A class representing a window on the screen.
        * For example:
        * <pre>
        *    Window win = new Window(parent);
        *    win.show();
        * </pre>
        *
        * @author  Sami Shaio
        * @version 1.13, 06/08/06
        * @see     java.awt.BaseWindow
        * @see     java.awt.Button
        */
       class Window extends BaseWindow {
          ...
       }


   Field Documentation Tags
       The following are the tags that can appear in the documentation comment
       for a field.

       An example of a field comment:

           /**
            * The X-coordinate of the component.
            *
            * @see #getLocation()
            */
           int x = 1263732;


   Constructor and Method Documentation Tags
       The following are the tags that can appear in the documentation comment
       for a constructor or method, except for @return, which cannot appear in
       a constructor, and {@inheritDoc}, which has certain restrictions. The
       @serialData tag can only be used in the doc comment for certain
       serialization methods.

       An example of a method doc comment:

           /**
            * Returns the character at the specified index. An index
            * ranges from <code>0</code> to <code>length() - 1</code>.
            *
            * @param     index  the index of the desired character.
            * @return    the desired character.
            * @exception StringIndexOutOfRangeException
            *              if the index is not in the range <code>0</code>
            *              to <code>length()-1</code>.
            * @see       java.lang.Character#charValue()
            */
           public char charAt(int index) {
              ...
           }


OPTIONS
       The javadoc tool uses doclets to determine its output. The Javadoc tool
       uses the default standard doclet unless a custom doclet is specified
       with the -doclet option. The Javadoc tool provides a set of
       command-line options that can be used with any doclet -- these options
       are described below under the sub-heading Javadoc Options. The standard
       doclet provides an additional set of command-line options that are
       described below under the sub-heading Options Provided by the Standard
       Doclet. All option names are case-insensitive, though their arguments
       can be case-sensitive.

       The options are:

       Options shown in italic are the Javadoc core options, which are
       provided by the front end of the Javadoc tool and are available to all
       doclets. The standard doclet itself provides the non-italic options.

   Javadoc Options
          -overview  path/filename
             Specifies that javadoc should retrieve the text for the overview
             documentation from the "source" file specified by path/filename
             and place it on the Overview page (overview-summary.html). The
             path/filename is relative to the -sourcepath.

          While you can use any name you want for filename and place it
          anywhere you want for path, a typical thing to do is to name it
          overview.html and place it in the source tree at the directory that
          contains the topmost package directories. In this location, no path
          is needed when documenting packages, since -sourcepath will point to
          this file. For example, if the source tree for the java.lang package
          is /src/classes/java/lang/, then you could place the overview file
          at /src/classes/overview.html. See Real World Example.

          For information about the file specified by path/filename, see
          overview comment file.

          Note that the overview page is created only if you pass into javadoc
          two or more package names. For further explanation, see HTML
          Frames.)

          The title on the overview page is set by -doctitle.

          -public
             Shows only public classes and members.

          -protected
             Shows only protected and public classes and members. This is the
             default.

          -package
             Shows only package, protected, and public classes and members.

          -private
             Shows all classes and members.

          -help
             Displays the online help, which lists these javadoc and doclet
             command line options.

          -doclet  class
             Specifies the class file that starts the doclet used in
             generating the documentation. Use the fully-qualified name. This
             doclet defines the content and formats the output. If the -doclet
             option is not used, javadoc uses the standard doclet for
             generating the default HTML format. This class must contain the
             start(Root) method. The path to this starting class is defined by
             the -docletpath option.

          For example, to call the MIF doclet, use:
              -doclet com.sun.tools.doclets.mif.MIFDoclet

          For full, working examples of running a particular doclet, see
          Running the MIF Doclet @
          http://java.sun.com/j2se/javadoc/mifdoclet/docs/mifdoclet.html#runningmifdoclet.

          -docletpath  classpathlist
             Specifies the path to the doclet starting class file (specified
             with the -doclet option) and any jar files it depends on. If the
             starting class file is in a jar file, then this specifies the
             path to that jar file, as shown in the example below. You can
             specify an absolute path or a path relative to the current
             directory. If classpathlist contains multiple paths or jar files,
             they should be separated with a colon (:) on Solaris and a
             semi-colon (;) on Windows. This option is not necessary if the
             doclet starting class is already in the search path.

          Example of path to jar file that contains the starting doclet class
          file. Notice the jar filename is included.
             -docletpath /home/user/mifdoclet/lib/mifdoclet.jar
          Example of path to starting doclet class file. Notice the class
          filename is omitted.
             -docletpath /home/user/mifdoclet/classes/com/sun/tools/doclets/mif/
          For full, working examples of running a particular doclet, see
          Running the MIF Doclet @
          http://java.sun.com/j2se/javadoc/mifdoclet/docs/mifdoclet.html#runningmifdoclet.

          -1.1
             This feature has been removed from Javadoc 1.4. There is no
             replacement for it. This option created documentation with the
             appearance and functionality of documentation generated by
             Javadoc 1.1 (it never supported nested classes). If you need this
             option, use Javadoc 1.2 or 1.3 instead.

          -source release
             Specifies the version of source code accepted. The following
             values for release are allowed:

          Use the value of release corresponding to that used when compiling
          the code with javac.

          -sourcepath  sourcepathlist
             Specifies the search paths for finding source files (.java) when
             passing package names or -subpackages into the javadoc command.
             The sourcepathlist can contain multiple paths by separating them
             with a colon (:). The Javadoc tool will search in all
             subdirectories of the specified paths. Note that this option is
             not only used to locate the source files being documented, but
             also to find source files that are not being documented but whose
             comments are inherited by the source files being documented.

          Note that you can use the -sourcepath option only when passing
          package names into the javadoc command -- it will not locate .java
          files passed into the javadoc command. (To locate .java files, cd to
          that directory or include the path ahead of each file, as shown at
          Documenting One or More Classes.) If -sourcepath is omitted, javadoc
          uses the class path to find the source files (see -classpath).
          Therefore, the default -sourcepath is the value of class path. If
          -classpath is omitted and you are passing package names into
          javadoc, it looks in the current directory (and subdirectories) for
          the source files.

          Set sourcepathlist to the root directory of the source tree for the
          package you are documenting. For example, suppose you want to
          document a package called com.mypackage whose source files are
          located at:
            /home/user/src/com/mypackage/*.java
          In this case you would specify the sourcepath to /home/user/src, the
          directory that contains com/mypackage, and then supply the package
          name com.mypackage:
            % javadoc -sourcepath /home/user/src/ com.mypackage
          This is easy to remember by noticing that if you concatenate the
          value of sourcepath and the package name together and change the dot
          to a slash "/", you end up with the full path to the package:
          /home/user/src/com/mypackage.

          To point to two source paths:
            % javadoc -sourcepath /home/user1/src:/home/user2/src com.mypackage

          -classpath  classpathlist
             Specifies the paths where javadoc will look for referenced
             classes (.class files) -- these are the documented classes plus
             any classes referenced by those classes. The classpathlist can
             contain multiple paths by separating them with a colon (:). The
             Javadoc tool will search in all subdirectories of the specified
             paths. Follow the instructions in class path documentation for
             specifying classpathlist.

          If -sourcepath is omitted, the Javadoc tool uses -classpath to find
          the source files as well as class files (for backward
          compatibility). Therefore, if you want to search for source and
          class files in separate paths, use both -sourcepath and -classpath.

          For example, if you want to document com.mypackage, whose source
          files reside in the directory /home/user/src/com/mypackage, and if
          this package relies on a library in /home/user/lib, you would
          specify:
            % javadoc -classpath /home/user/lib -sourcepath /home/user/src com.mypackage
          As with other tools, if you do not specify -classpath, the Javadoc
          tool uses the CLASSPATH environment variable, if it is set. If both
          are not set, the Javadoc tool searches for classes from the current
          directory.

          For an in-depth description of how the Javadoc tool uses -classpath
          to find user classes as it relates to extension classes and
          bootstrap classes, see How Classes Are Found.

          As a special convenience, a class path element containing a basename
          of * is considered equivalent to specifying a list of all the files
          in the directory with the extension .jar or .JAR (a java program
          cannot tell the difference between the two invocations).
          For example, if directory foo contains a.jar and b.JAR, then the
          class path element foo/* is expanded to a A.jar:b.JAR, except that
          the order of jar files is unspecified. All jar files in the
          specified directory, even hidden ones, are included in the list. A
          classpath entry consisting simply of * expands to a list of all the
          jar files in the current directory. The CLASSPATH environment
          variable, where defined, will be similarly expanded. Any classpath
          wildcard expansion occurs before the Java virtual machine is started
          -- no Java program will ever see unexpanded wildcards except by
          querying the environment. For example; by invoking
          System.getenv("CLASSPATH").

          -subpackages  package1:package2:...
             Generates documentation from source files in the specified
             packages and recursively in their subpackages. This option is
             useful when adding new subpackages to the source code, as they
             are automatically included. Each package argument is any
             top-level subpackage (such as java) or fully qualified package
             (such as javax.swing) that does not need to contain source files.
             Arguments are separated by colons (on all operating systmes).
             Wildcards are not needed or allowed. Use -sourcepath to specify
             where to find the packages. This option is smart about not
             processing source files that are in the source tree but do not
             belong to the packages, as described at processing of source
             files.

          For example:
            % javadoc -d docs -sourcepath /home/user/src -subpackages java:javax.swing
          This command generates documentation for packages named "java" and
          "javax.swing" and all their subpackages.

          You can use -subpackages in conjunction with -exclude to exclude
          specific packages.

          -exclude  packagename1:packagename2:...
             Unconditionally excludes the specified packages and their
             subpackages from the list formed by -subpackages. It excludes
             those packages even if they would otherwise be included by some
             previous or later -subpackages option. For example:
               % javadoc -sourcepath /home/user/src -subpackages java -exclude java.net:java.lang
             would include java.io, java.util, and java.math (among others),
             but would exclude packages rooted at java.net and java.lang.
             Notice this excludes java.lang.ref, a subpackage of java.lang).

          -bootclasspath  classpathlist
             Specifies the paths where the boot classes reside. These are
             nominally the Java platform classes. The bootclasspath is part of
             the search path the Javadoc tool will use to look up source and
             class files. See How Classes Are Found. for more details.
             Separate directories in classpathlist with colons (:).

          -extdirs  dirlist
             Specifies the directories where extension classes reside. These
             are any classes that use the Java Extension mechanism. The
             extdirs is part of the search path the Javadoc tool will use to
             look up source and class files. See -classpath (above) for more
             details. Separate directories in dirlist with colons (:).

          -verbose
             Provides more detailed messages while javadoc is running. Without
             the verbose option, messages appear for loading the source files,
             generating the documentation (one message per source file), and
             sorting. The verbose option causes the printing of additional
             messages specifying the number of milliseconds to parse each java
             source file.

          -quiet
             Shuts off non-error and non-warning messages, leaving only the
             warnings and errors appear, making them easier to view. Also
             suppresses the version string.

          -breakiterator
             Uses the internationalized sentence boundary of
             java.text.BreakIterator to determine the end of the first
             sentence for English (all other locales already use
             BreakIterator), rather than an English language, locale-specific
             algorithm. By first sentence, we mean the first sentence in the
             main description of a package, class or member. This sentence is
             copied to the package, class or member summary, and to the
             alphabetic index.

          From JDK 1.2 forward, the BreakIterator class is already used to
          determine the end of sentence for all languages but English.
          Therefore, the -breakiterator option has no effect except for
          English from 1.2 forward. English has its own default algorithm:

             o English default sentence-break algorithm - Stops at a period
               followed by a space or a HTML block tag, such as <P>.

             o Breakiterator sentence-break algorithm - In general, stops at a
               period, question mark or exclamation mark followed by a space
               if the next word starts with a capital letter. This is meant to
               handle most abbreviations (such as "The serial no. is valid",
               but won't handle "Mr. Smith"). Doesn't stop at HTML tags or
               sentences that begin with numbers or symbols. Stops at the last
               period in "../filename", even if embedded in an HTML tag.


             NOTE: We have removed from 1.5.0 the breakiterator warning
             messages that were in 1.4.x and have left the default
             sentence-break algorithm unchanged. That is, the -breakiterator
             option is not the default in 1.5.0, nor do we expect it to become
             the default. This is a reversal from our former intention that
             the default would change in the "next major release" (1.5.0).
             This means if you have not modified your source code to eliminate
             the breakiterator warnings in 1.4.x, then you don't have to do
             anything, and the warnings go away starting with 1.5.0. The
             reason for this reversal is because any benefit to having
             breakiterator become the default would be outweighed by the
             incompatible source change it would require. We regret any extra
             work and confusion this has caused.

          -locale  language_country_variant

             Important - The -locale option must be placed ahead (to the left)
             of any options provided by the standard doclet or any other
             doclet. Otherwise, the navigation bars will appear in English.
             This is the only command-line option that is order-dependent.

          Specifies the locale that javadoc uses when generating
          documentation. The argument is the name of the locale, as described
          in java.util.Locale documentation, such as en_US (English, United
          States) or en_US_WIN (Windows variant).

          Specifying a locale causes javadoc to choose the resource files of
          that locale for messages (strings in the navigation bar, headings
          for lists and tables, help file contents, comments in
          stylesheet.css, and so forth). It also specifies the sorting order
          for lists sorted alphabetically, and the sentence separator to
          determine the end of the first sentence. It does not determine the
          locale of the doc comment text specified in the source files of the
          documented classes.

          -encoding  name
             Specifies the encoding name of the source files, such as
             EUCJIS/SJIS. If this option is not specified, the platform
             default converter is used.

          Also see -docencoding and -charset.

          -Jflag
             Passes flag directly to the runtime system java that runs
             javadoc. Notice there must be no space between the J and the
             flag. For example, if you need to ensure that the system sets
             aside 32 megabytes of memory in which to process the generated
             documentation, then you would call the -Xmx option of java as
             follows (-Xms is optional, as it only sets the size of initial
             memory, which is useful if you know the minimum amount of memory
             required):
                % javadoc -J-Xmx32m -J-Xms32m com.mypackage
             To tell what version of javadoc you are using, call the
             "-version" option of java:
                % javadoc -J-version
                java version "1.2"
                Classic VM (build JDK-1.2-V, green threads, sunwjit)
             (The version number of the standard doclet appears in its output
             stream.)

   Options Provided by the Standard Doclet
          -d  directory
             Specifies the destination directory where javadoc saves the
             generated HTML files. (The "d" means "destination.") Omitting
             this option causes the files to be saved to the current
             directory. The value directory can be absolute, or relative to
             the current working directory. As of 1.4, the destination
             directory is automatically created when javadoc is run.

          For example, the following generates the documentation for the
          package com.mypackage and saves the results in the /home/user/doc/
          directory:
            % javadoc -d /home/user/doc com.mypackage

          -use
             Includes one "Use" page for each documented class and package.
             The page describes what packages, classes, methods, constructors
             and fields use any API of the given class or package. Given class
             C, things that use class C would include subclasses of C, fields
             declared as C, methods that return C, and methods and
             constructors with parameters of type C.

          For example, let's look at what might appear on the "Use" page for
          String. The getName() method in the java.awt.Font class returns type
          String. Therefore, getName() uses String, and you will find that
          method on the "Use" page for String.

          Note that this documents only uses of the API, not the
          implementation. If a method uses String in its implementation but
          does not take a string as an argument or return a string, that is
          not considered a "use" of String.

          You can access the generated "Use" page by first going to the class
          or package, then clicking on the "Use" link in the navigation bar.

          -version
             Includes the @version text in the generated docs. This text is
             omitted by default. To tell what version of the Javadoc tool you
             are using, use the -J-version option.

          -author
             Includes the @author text in the generated docs.

          -splitindex
             Splits the index file into multiple files, alphabetically, one
             file per letter, plus a file for any index entries that start
             with non-alphabetical characters.

          -windowtitle  title
             Specifies the title to be placed in the HTML <title> tag. This
             appears in the window title and in any browser bookmarks
             (favorite places) that someone creates for this page. This title
             should not contain any HTML tags, as the browser will not
             properly interpret them. Any internal quotation marks within
             title may have to be escaped. If -windowtitle is omitted, the
             Javadoc tool uses the value of -doctitle for this option.
               % javadoc -windowtitle "Java 2 Platform" com.mypackage

          -doctitle  title
             Specifies the title to be placed near the top of the overview
             summary file. The title will be placed as a centered, level-one
             heading directly beneath the upper navigation bar. The title may
             contain html tags and white space, though if it does, it must be
             enclosed in quotes. Any internal quotation marks within title may
             have to be escaped.
               % javadoc -doctitle "Java<sup><font size=\"-2\">TM</font></sup>" com.mypackage

          -title  title
             This option no longer exists. It existed only in Beta versions of
             Javadoc 1.2. It has been renamed to -doctitle. This option is
             being renamed to make it clear that it defines the document title
             rather than the window title.

          -header  header
             Specifies the header text to be placed at the top of each output
             file. The header will be placed to the right of the upper
             navigation bar. header may contain HTML tags and white space,
             though if it does, it must be enclosed in quotes. Any internal
             quotation marks within header may have to be escaped.
               % javadoc -header "<b>Java 2 Platform </b><br>v1.4" com.mypackage

          -footer  footer
             Specifies the footer text to be placed at the bottom of each
             output file. The footer will be placed to the right of the lower
             navigation bar. footer may contain html tags and white space,
             though if it does, it must be enclosed in quotes. Any internal
             quotation marks within footer may have to be escaped.

          -bottom  text
             Specifies the text to be placed at the bottom of each output
             file. The text will be placed at the bottom of the page, below
             the lower navigation bar. The text may contain HTML tags and
             white space, though if it does, it must be enclosed in quotes.
             Any internal quotation marks within text may have to be escaped.

          -link  extdocURL
             Creates links to existing javadoc-generated documentation of
             external referenced classes. It takes one argument:

             o extdocURL is the absolute or relative URL of the directory
               containing the external javadoc-generated documentation you
               want to link to. Examples are shown below. The package-list
               file must be found in this directory (otherwise, use
               -linkoffline). The Javadoc tool reads the package names from
               the package-list file and then links to those packages at that
               URL. When the Javadoc tool is run, the extdocURL value is
               copied literally into the <A HREF> links that are created.
               Therefore, extdocURL must be the URL to the directory, not to a
               file.

             You can use an absolute link for extdocURL to enable your docs to
             link to a document on any website, or can use a relative link to
             link only to a relative location. If relative, the value you pass
             in should be the relative path from the destination directory
             (specified with -d) to the directory containing the packages
             being linked to.

             When specifying an absolute link you normally use an http: link.
             However, if you want to link to a file system that has no web
             server, you can use a file: link -- however, do this only if
             everyone wanting to access the generated documentation shares the
             same file system.

             In all cases, and on all operating systems, you should use a
             forward slash as the separator, whether the URL is absolute or
             relative, and "http:" or "file:" based (as specified in the URL
             Memo @
             http://www.ietf.org/rfc/rfc1738.txt).

                Absolute http: based link:
                   -link http://<host>/<directory>/<directory>/.../<name>

                Absolute file: based link:
                   -link file://<host>/<directory>/<directory>/.../<name>

                Relative link:
                   -link <directory>/<directory>/.../<name>

          You can specify multiple -link options in a given javadoc run to
          link to multiple documents. Choosing between -linkoffline and -link:
          Use -link:

             o when using a relative path to the external API document, or

             o when using an absolute URL to the external API document, if
               your shell allows a program to open a connection to that URL
               for reading.
          Use -linkoffline:

             o when using an absolute URL to the external API document, if
               your shell does not allow a program to open a connection to
               that URL for reading. This can occur if you are behind a
               firewall and the document you want to link to is on the other
               side.

          Example using absolute links to the external docs - Let's say you
          want to link to the java.lang, java.io and other Java 2 Platform
          packages at http://java.sun.com/j2se/1.5.0/docs/api @
          http://java.sun.com/j2se/1.5.0/docs/api, The following command
          generates documentation for the package com.mypackage with links to
          the Java 2 Platform packages. The generated documentation will
          contain links to the Object class, for example, in the class trees.
          (Other options, such as -sourcepath and -d, are not shown.)
            % javadoc -link http://java.sun.com/j2se/1.5.0/docs/api com.mypackage
          Example using relative links to the external docs - Let's say you
          have two packages whose docs are generated in different runs of the
          Javadoc tool, and those docs are separated by a relative path. In
          this example, the packages are com.apipackage, an API, and
          com.spipackage, an SPI (Service Provide Interface). You want the
          documentation to reside in docs/api/com/apipackage and
          docs/spi/com/spipackage. Assuming the API package documentation is
          already generated, and that docs is the current directory, you would
          document the SPI package with links to the API documentation by
          running:
            % javadoc -d ./spi -link ../api com.spipackage

          Notice the -link argument is relative to the destination directory
          (docs/spi).

          Details - The -link option enables you to link to classes referenced
          to by your code but not documented in the current javadoc run. For
          these links to go to valid pages, you must know where those HTML
          pages are located, and specify that location with extdocURL. This
          allows, for instance, third party documentation to link to java.*
          documentation on http://java.sun.com.

          Omit the -link option for javadoc to create links only to API within
          the documentation it is generating in the current run. (Without the
          -link option, the Javadoc tool does not create links to
          documentation for external references, because it does not know if
          or where that documentation exists.)

          This option can create links in several places in the generated
          documentation.

          Another use is for cross-links between sets of packages: Execute
          javadoc on one set of packages, then run javadoc again on another
          set of packages, creating links both ways between both sets.

          How a Class Must be Referenced - For a link to an external
          referenced class to actually appear (and not just its text label),
          the class must be referenced in the following way. It is not
          sufficient for it to be referenced in the body of a method. It must
          be referenced in either an import statement or in a declaration.
          Here are examples of how the class java.io.File can be referenced:

             o In any kind of import statement: by wildcard import, import
               explicitly by name, or automatically import for java.lang.*.
               For example, this would suffice:
               import java.io.*;
               In 1.3.x and 1.2.x, only an explicit import by name works -- a
               wildcard import statement does not work, nor does the automatic
               import java.lang.*.

             o In a declaration:
               void foo(File f) {}
               The reference and be in the return type or parameter type of a
               method, constructor, field, class or interface, or in an
               implements, extends or throws statement.

          An important corollary is that when you use the -link option, there
          may be many links that unintentionally do not appear due to this
          constraint. (The text would appear without a hypertext link.) You
          can detect these by the warnings they emit. The most innocuous way
          to properly reference a class and thereby add the link would be to
          import that class, as shown above.

          Package List - The -link option requires that a file named
          package-list, which is generated by the Javadoc tool, exist at the
          URL you specify with -link. The package-list file is a simple text
          file that lists the names of packages documented at that location.
          In the earlier example, the Javadoc tool looks for a file named
          package-list at the given URL, reads in the package names and then
          links to those packages at that URL.

          For example, the package list for the Java 2 Platform 5.0 API is
          located at http://java.sun.com/j2se/1.5.0/docs/api/package-list @
          http://java.sun.com/j2se/1.5.0/docs/api/package-list. and starts out
          as follows:
            java.applet
            java.awt
            java.awt.color
            java.awt.datatransfer
            java.awt.dnd
            java.awt.event
            java.awt.font
            etc.

          When javadoc is run without the -link option, when it encounters a
          name that belongs to an external referenced class, it prints the
          name with no link. However, when the -link option is used, the
          Javadoc tool searches the package-list file at the specified
          extdocURL location for that package name. If it finds the package
          name, it prefixes the name with extdocURL.

          In order for there to be no broken links, all of the documentation
          for the external references must exist at the specified URLs. The
          Javadoc tool will not check that these pages exist -- only that the
          package-list exists.

          Multiple Links - You can supply multiple -link options to link to
          any number of external generated documents.   Javadoc 1.2 has a
          known bug which prevents you from supplying more than one -link
          command. This was fixed in 1.2.2.

          Specify a different link option for each external document to link
          to:

             % javadoc -link extdocURL1 -link extdocURL2 ... -link extdocURLn
          com.mypackage

          where extdocURL1,  extdocURL2,  ... extdocURLn point respectively to
          the roots of external documents, each of which contains a file named
          package-list.

          Cross-links - Note that "bootstrapping" may be required when
          cross-linking two or more documents that have not previously been
          generated. In other words, if package-list does not exist for either
          document, when you run the Javadoc tool on the first document, the
          package-list will not yet exist for the second document. Therefore,
          to create the external links, you must re-generate the first
          document after generating the second document.

          In this case, the purpose of first generating a document is to
          create its package-list (or you can create it by hand it if you're
          certain of the package names). Then generate the second document
          with its external links. The Javadoc tool prints a warning if a
          needed external package-list file does not exist.

          -linkoffline  extdocURL  packagelistLoc
             This option is a variation of -link; they both create links to
             javadoc-generated documentation for external referenced classes.
             Use the -linkoffline option when linking to a document on the web
             when the Javadoc tool itself is "offline" -- that is, it cannot
             access the document through a web connection.

          More specifically, use -linkoffline if the external document's
          package-list file is not accessible or does not exist at the
          extdocURL location but does exist at a different location, which can
          be specified by packageListLoc (typically local). Thus, if extdocURL
          is accessible only on the World Wide Web, -linkoffline removes the
          constraint that the Javadoc tool have a web connection when
          generating the documentation.

          Another use is as a "hack" to update docs: After you have run
          javadoc on a full set of packages, then you can run javadoc again on
          onlya smaller set of changed packages, so that the updated files can
          be inserted back into the original set. Examples are given below.

          The -linkoffline option takes two arguments -- the first for the
          string to be embedded in the <a href> links, the second telling it
          where to find package-list:

             o extdocURL is the absolute or relative URL of the directory
               containing the external javadoc-generated documentation you
               want to link to. If relative, the value should be the relative
               path from the destination directory (specified with -d) to the
               root of the packages being linked to. For more details, see
               extdocURL in the -link option.

             o packagelistLoc is the path or URL to the directory containing
               the package-list file for the external documentation. This can
               be a URL (http: or file:) or file path, and can be absolute or
               relative. If relative, make it relative to the current
               directory from where javadoc was run. Do not include the
               package-list filename.

          You can specify multiple -linkoffline options in a given javadoc
          run. (Prior to 1.2.2, it could be specified only once.)

          Example using absolute links to the external docs - Let's say you
          want to link to the java.lang, java.io and other Java 2 Platform
          packages at http://java.sun.com/j2se/1.5.0/docs/api, but your shell
          does not have web access. You could open the package-list file in a
          browser at http://java.sun.com/j2se/1.5.0/docs/api/package-list @
          http://java.sun.com/j2se/1.5.0/docs/api/package-list, save it to a
          local directory, and point to this local copy with the second
          argument, packagelistLoc. In this example, the package list file has
          been saved to the current directory "." . The following command
          generates documentation for the package com.mypackage with links to
          the Java 2 Platform packages. The generated documentation will
          contain links to the Object class, for example, in the class trees.
          (Other necessary options, such as -sourcepath, are not shown.)
          % javadoc -linkoffline http://java.sun.com/j2se/1.5.0/docs/api . com.mypackage

          Example using relative links to the external docs - It's not very
          common to use -linkoffline with relative paths, for the simple
          reason that -link usually suffices. When using -linkoffline, the
          package-list file is generally local, and when using relative links,
          the file you are linking to is also generally local. So it is
          usually unnecessary to give a different path for the two arguments
          to -linkoffline. When the two arguments are identical, you can use
          -link. See the -link relative example.

          Manually Creating a package-list File - If a package-list file does
          not yet exist, but you know what package names your document will
          link to, you can create your own copy of this file by hand and
          specify its path with packagelistLoc. An example would be the
          previous case where the package list for com.spipackage did not
          exist when com.apipackage was first generated. This technique is
          useful when you need to generate documentation that links to new
          external documentation whose package names you know, but which is
          not yet published. This is also a way of creating package-list files
          for packages generated with Javadoc 1.0 or 1.1, where package-list
          files were not generated. Likewise, two companies can share their
          unpublished package-list files, enabling them to release their
          cross-linked documentation simultaneously.

          Linking to Multiple Documents - You can include -linkoffline once
          for each generated document you want to refer to (each option is
          shown on a separate line for clarity):

          % javadoc -linkoffline extdocURL1 packagelistLoc1 \
                    -linkoffline extdocURL2 packagelistLoc2 \
                    ...

          Updating docs - Another use for -linkoffline option is useful if
          your project has dozens or hundreds of packages, if you have already
          run javadoc on the entire tree, and now, in a separate run, you want
          to quickly make some small changes and re-run javadoc on just a
          small portion of the source tree. This is somewhat of a hack in that
          it works properly only if your changes are only to doc comments and
          not to declarations. If you were to add, remove or change any
          declarations from the source code, then broken links could show up
          in the index, package tree, inherited member lists, use page, and
          other places.

          First, you create a new destination directory (call it update) for
          this new small run. Let's say the original destination directory was
          named html. In the simplest example, cd to the parent of html. Set
          the first argument of -linkoffline to the current directory "." and
          set the second argument to the relative path to html, where it can
          find package-list, and pass in only the package names of the
          packages you want to update:
            % javadoc -d update -linkoffline . html com.mypackage
          When the Javadoc tool is done, copy these generated class pages in
          update/com/package (not the overview or index), over the original
          files in html/com/package.

          -linksource
             Creates an HTML version of each source file (with line numbers)
             and adds links to them from the standard HTML documentation.
             Links are created for classes, interfaces, constructors, methods
             and fields whose declarations are in a source file. Otherwise,
             links are not created, such as for default constructors and
             generated classes.

          This option exposes all private implementation details in the
          included source files, including private classes, private fields,
          and the bodies of private methods, regardless of the -public,
          -package, -protected and -private options. Unless you also use the
          -private option, not all private classes or interfaces will
          necessarily be accessible via links.

          Each link appears on the name of the identifier in its declaration.
          For example, the link to the source code of the Button class would
          be on the word "Button":
              public class Button
              extends Component
              implements Accessible
          and the link to the source code of the getLabel() method in the
          Button class would be on the word "getLabel":
              public String getLabel()

          -group  groupheading  packagepattern:packagepattern:...
             Separates packages on the overview page into whatever groups you
             specify, one group per table. You specify each group with a
             different -group option. The groups appear on the page in the
             order specified on the command line; packages are alphabetized
             within a group. For a given -group option, the packages matching
             the list of packagepattern expressions appear in a table with the
             heading groupheading.

             o groupheading can be any text, and can include white space. This
               text is placed in the table heading for the group.

             o packagepattern can be any package name, or can be the start of
               any package name followed by an asterisk (*). The asterisk is a
               wildcard meaning "match any characters". This is the only
               wildcard allowed. Multiple patterns can be included in a group
               by separating them with colons (:).


             NOTE: If using an asterisk in a pattern or pattern list, the
             pattern list must be inside quotes, such as
             "java.lang*:java.util"

          If you do not supply any -group option, all packages are placed in
          one group with the heading "Packages". If the all groups do not
          include all documented packages, any leftover packages appear in a
          separate group with the heading "Other Packages".

          For example, the following option separates the four documented
          packages into core, extension and other packages. Notice the
          trailing "dot" does not appear in "java.lang*" -- including the dot,
          such as "java.lang.*" would omit the java.lang package.
            % javadoc -group "Core Packages" "java.lang*:java.util"
                      -group "Extension Packages" "javax.*"
                      java.lang java.lang.reflect java.util javax.servlet java.new
          This results in the groupings:

                Core Packages
                   java.lang java.lang.reflect java.util

                Extension Packages
                   javax.servlet

                Other Packages
                   java.new


          -nodeprecated
             Prevents the generation of any deprecated API at all in the
             documentation. This does what -nodeprecatedlist does, plus it
             does not generate any deprecated API throughout the rest of the
             documentation. This is useful when writing code and you don't
             want to be distracted by the deprecated code.

          -nodeprecatedlist
             Prevents the generation of the file containing the list of
             deprecated APIs (deprecated-list.html) and the link in the
             navigation bar to that page. (However, javadoc continues to
             generate the deprecated API throughout the rest of the document.)
             This is useful if your source code contains no deprecated API,
             and you want to make the navigation bar cleaner.

          -nosince
             Omits from the generated docs the "Since" sections associated
             with the @since tags.

          -notree
             Omits the class/interface hierarchy pages from the generated
             docs. These are the pages you reach using the "Tree" button in
             the navigation bar. The hierarchy is produced by default.

          -noindex
             Omits the index from the generated docs. The index is produced by
             default.

          -nohelp
             Omits the HELP link in the navigation bars at the top and bottom
             of each page of output.

          -nonavbar
             Prevents the generation of the navigation bar, header and footer,
             otherwise found at the top and bottom of the generated pages. Has
             no affect on the "bottom" option. The -nonavbar option is useful
             when you are interested only in the content and have no need for
             navigation, such as converting the files to PostScript or PDF for
             print only.

          -helpfile  path/filename
             Specifies the path of an alternate help file path/filename that
             the HELP link in the top and bottom navigation bars link to.
             Without this option, the Javadoc tool automatically creates a
             help file help-doc.html that is hard-coded in the Javadoc tool.
             This option enables you to override this default. The filename
             can be any name and is not restricted to help-doc.html -- the
             Javadoc tool will adjust the links in the navigation bar
             accordingly. For example:
               % javadoc -helpfile /home/user/myhelp.html java.awt

          -stylesheetfile  path/filename
             Specifies the path of an alternate HTML stylesheet file. Without
             this option, the Javadoc tool automatically creates a stylesheet
             file stylesheet.css that is hard-coded in the Javadoc tool. This
             option enables you to override this default. The filename can be
             any name and is not restricted to stylesheet.css. For example:
               % javadoc -stylesheetfile /home/user/mystylesheet.css com.mypackage

          -serialwarn
             Generates compile-time warnings for missing @serial tags. By
             default, Javadoc 1.2.2 (and later versions) generates no serial
             warnings. (This is a reversal from earlier versions.) Use this
             option to display the serial warnings, which helps to properly
             document default serializable fields and writeExternal methods.

          -charset  name
             Specifies the HTML character set for this document. The name
             should be a preferred MIME name as given in the IANA Registry @
             http://www.iana.org/assignments/character-sets. For example:
               % javadoc -charset "iso-8859-1" mypackage
             would insert the following line in the head of every generated
             page:
                <META http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
             This META tag is described in the HTML standard @
             http://www.w3.org/TR/REC-html40/charset.html#h-5.2.2. (4197265
             and 4137321)

          Also see -encoding and -docencoding.

          -docencoding  name
             Specifies the encoding of the generated HTML files. The name
             should be a preferred MIME name as given in the IANA Registry @
             http://www.iana.org/assignments/character-sets. If you omit this
             option but use -encoding, then the encoding of the generated HTML
             files is determined by -encoding. Example:
               % javadoc -docencoding "ISO-8859-1" mypackage
             Also see -encoding and -charset.

          -keywords
             Adds HTML meta keyword tags to the generated file for each class.
             These tags can help the page be found by search engines that look
             for meta tags. (Most search engines that search the entire
             Internet do not look at meta tags, because pages can misuse them;
             but search engines offered by companies that confine their search
             to their own website can benefit by looking at meta tags.)

          The meta tags include the fully qualified name of the class and the
          unqualified names of the fields and methods. Constructors are not
          included because they are identical to the class name. For example,
          the class String starts with these keywords:
               <META NAME="keywords" CONTENT="java.lang.String class">
               <META NAME="keywords" CONTENT="CASE_INSENSITIVE_ORDER">
               <META NAME="keywords" CONTENT="length()">
               <META NAME="keywords" CONTENT="charAt()">

          -tag  tagname:Xaoptcmf:"taghead"
             Enables the Javadoc tool to interpret a simple, one-argument
             custom block tag @tagname in doc comments. So the Javadoc tool
             can "spell-check" tag names, it is important to include a -tag
             option for every custom tag that is present in the source code,
             disabling (with X) those that are not being output in the current
             run.

          The colon (:) is always the separator. To use a colon in tagname,
          see Use of Colon in Tag Name.

          The -tag option outputs the tag's heading taghead in bold, followed
          on the next line by the text from its single argument, as shown in
          the example below. Like any block tag, this argument's text can
          contain inline tags, which are also interpreted. The output is
          similar to standard one-argument tags, such as @return and @author.
          Omitting taghead causes tagname to appear as the heading.

          Placement of tags - The Xaoptcmf part of the argument determines
          where in the source code the tag is allowed to be placed, and
          whether the tag can be disabled (using X). You can supply either a,
          to allow the tag in all places, or any combination of the other
          letters: X (disable tag)
          a (all)
          o (overview)
          p (packages)
          t (types, that is classes and interfaces)
          c (constructors)
          m (methods)
          f (fields)

          Examples of single tags - An example of a tag option for a tag that
          that can be used anywhere in the source code is:
              -tag todo:a:"To Do:"
          If you wanted @todo to be used only with constructors, methods and
          fields, you would use:
              -tag todo:cmf:"To Do:"
          Notice the last colon (:) above is not a parameter separator, but is
          part of the heading text (as shown below). You would use either tag
          option for source code that contains the tag @todo, such as:
               @todo The documentation for this method needs work.
          Use of Colon in Tag Name - A colon can be used in a tag name if it
          is escaped with a backslash. For this doc comment:
              /**
               * @ejb:bean
               */
          use this tag option:
              -tag ejb\\:bean:a:"EJB Bean:"
          Spell-checking tag names (Disabling tags) - Some developers put
          custom tags in the source code that they don't always want to
          output. In these cases, it is important to list all tags that are
          present in the source code, enabling the ones you want to output and
          disabling the ones you don't want to output. The presence of X
          disables the tag, while its absence enables the tag. This gives the
          Javadoc tool enough information to know if a tag it encounters is
          unknown, probably the results of a typo or a misspelling. It prints
          a warning in these cases.

          You can add X to the placement values already present, so that when
          you want to enable the tag, you can simply delete the X. For
          example, if @todo is a tag that you want to suppress on output, you
          would use:
              -tag todo:Xcmf:"To Do:"
          or, if you'd rather keep it simple:
              -tag todo:X

          The syntax -tag todo:X works even if @todo is defined by a taglet.

          Order of tags - The order of the -tag (and -taglet) options
          determine the order the tags are output. You can mix the custom tags
          with the standard tags to intersperse them. The tag options for
          standard tags are placeholders only for determining the order --
          they take only the standard tag's name. (Subheadings for standard
          tags cannot be altered.) This is illustrated in the following
          example.

          If -tag is missing, then the position of -taglet determines its
          order. If they are both present, then whichever appears last on the
          command line determines its order. (This happens because the tags
          and taglets are processed in the order that they appear on the
          command line. For example, if -taglet and -tag both have the name
          "todo", the one that appears last on the command line will determine
          its order.

          Example of a complete set of tags - This example inserts "To Do"
          after "Parameters" and before "Throws" in the output. By using "X",
          it also specifies that @example is a tag that might be encountered
          in the source code that should not be output during this run. Notice
          that if you use @argfile, you can put the tags on separate lines in
          an argument file like this (no line continuation characters needed):
             -tag param
             -tag return
             -tag todo:a:"To Do:"
             -tag throws
             -tag see
             -tag example:X

          When javadoc parses the doc comments, any tag encountered that is
          neither a standard tag nor passed in with -tag or -taglet is
          considered unknown, and a warning is thrown.

          The standard tags are initially stored internally in a list in their
          default order. Whenever -tag options are used, those tags get
          appended to this list -- standard tags are moved from their default
          position. Therefore, if a -tag option is omitted for a standard tag,
          it remains in its default position.

          Avoiding Conflicts - If you want to slice out your own namespace,
          you can use a dot-separated naming convention similar to that used
          for packages: com.mycompany.todo. Sun will continue to create
          standard tags whose names do not contain dots. Any tag you create
          will override the behavior of a tag by the same name defined by Sun.
          In other words, if you create a tag or taglet @todo, it will always
          have the same behavior you define, even if Sun later creates a
          standard tag of the same name.

          Annotations vs. Javadoc Tags - In general, if the markup you want to
          add is intended to affect or produce documentation, it should
          probably be a javadoc tag; otherwise, it should be an annotation.
          See Comparing Annotations and Javadoc Tags @
          http://java.sun.com/j2se/javadoc/writingdoccomments/index.html#annotations

          You can also create more complex block tags, or custom inline tags
          with the -taglet option.

          -taglet  class
             Specifies the class file that starts the taglet used in
             generating the documentation for that tag. Use the
             fully-qualified name for class. This taglet also defines the
             number of text arguments that the custom tag has. The taglet
             accepts those arguments, processes them, and generates the
             output. For extensive documentation with example taglets, see:

             o Taglet Overview

          Taglets are useful for block or inline tags. They can have any
          number of arguments and implement custom behavior, such as making
          text bold, formatting bullets, writing out the text to a file, or
          starting other processes.

          Taglets can only determine where a tag should appear and in what
          form. All other decisions are made by the doclet. So a taglet cannot
          do things such as remove a class name from the list of included
          classes. However, it can execute side effects, such as printing the
          tag's text to a file or triggering another process.

          Use the -tagletpath option to specify the path to the taglet. Here
          is an example that inserts the "To Do" taglet after "Parameters" and
          ahead of "Throws" in the generated pages:
              -taglet com.sun.tools.doclets.ToDoTaglet
              -tagletpath /home/taglets
              -tag return
              -tag param
              -tag todo
              -tag throws
              -tag see

          Alternatively, you can use the -taglet option in place of its -tag
          option, but that may be harder to read.

          -tagletpath  tagletpathlist
             Specifies the search paths for finding taglet class files
             (.class). The tagletpathlist can contain multiple paths by
             separating them with a colon (:). The Javadoc tool will search in
             all subdirectories of the specified paths.

          -docfilessubdirs
             Enables deep copying of "doc-files" directories. In other words,
             subdirectories and all contents are recursively copied to the
             destination. For example, the directory doc-files/example/images
             and all its contents would now be copied. There is also an option
             to exclude subdirectories.

          -excludedocfilessubdir  name1:name2...
             Excludes any "doc-files" subdirectories with the given names.
             This prevents the copying of SCCS and other source-code-control
             subdirectories.

          -noqualifier  all  |  packagename1:packagename2:...
             Omits qualifying package name from ahead of class names in
             output. The argument to -noqualifier is either "all" (all package
             qualifiers are omitted) or a colon-separate list of packages,
             with wildcards, to be removed as qualifiers. The package name is
             removed from places where class or interface names appear.

          The following example omits all package qualifiers:
              -noqualifier all
          The following example omits "java.lang" and "java.io" package
          qualifiers:
              -noqualifier java.lang:java.io
          The following example omits package qualifiers starting with "java",
          and "com.sun" subpackages (but not "javax"):
              -noqualifier java.*:com.sun.*
          Where a package qualifier would appear due to the above behavior,
          the name can be suitably shortened -- see How a name is displayed.
          This rule is in effect whether or not -noqualifier is used.

          -notimestamp
             Suppresses the timestamp, which is hidden in an HTML comment in
             the generated HTML near the top of each page. Useful when you
             want to run javadoc on two source bases and diff them, as it
             prevents timestamps from causing a diff (which would otherwise be
             a diff on every page). The timestamp includes the javadoc version
             number, and currently looks like this:
                  <!-- Generated by javadoc (build 1.5.0-internal) on Tue Jun 22 09:57:24 PDT 2004 -->

          -nocomment
             Suppress the entire comment body, including the main description
             and all tags, generating only declarations. This option enables
             re-using source files originally intended for a different
             purpose, to produce skeleton HTML documentation at the early
             stages of a new project.

COMMAND LINE ARGUMENT FILES
       To shorten or simplify the javadoc command line, you can specify one or
       more files that themselves contain arguments to the javadoc command
       (except -J options). This enables you to create javadoc commands of any
       length on any operating system.

       An argument file can include javac options and source filenames in any
       combination. The arguments within a file can be space-separated or
       newline-separated. If a filename contains embedded spaces, put the
       whole filename in double quotes.

       Filenames within an argument file are relative to the current
       directory, not the location of the argument file. Wildcards (*) are not
       allowed in these lists (such as for specifying *.java). Use of the '@'
       character to recursively interpret files is not supported. The -J
       options are not supported because they are passed to the launcher,
       which does not support argument files.

       When executing javadoc, pass in the path and name of each argument file
       with the '@' leading character. When javadoc encounters an argument
       beginning with the character `@', it expands the contents of that file
       into the argument list.

   Example - Single Arg File
       You could use a single argument file named "argfile" to hold all
       Javadoc arguments:

         % javadoc @argfile


       This argument file could contain the contents of both files shown in
       the next example.

   Example - Two Arg Files
       You can create two argument files -- one for the Javadoc options and
       the other for the package names or source filenames: (Notice the
       following lists have no line-continuation characters.)

       Create a file named "options" containing:

            -d docs-filelist
            -use
            -splitindex
            -windowtitle 'Java 2 Platform v1.3 API Specification'
            -doctitle 'Java<sup><font size="-2">TM</font></sup> 2 Platform 5.0 API Specification'
            -header '<b>Java 2 Platform </b><br><font size="-1">5.0</font>'
            -bottom 'Copyright 1993-2000 Sun Microsystems, Inc. All Rights Reserved.'
            -group "Core Packages" "java.*"
            -overview /java/pubs/ws/1.5/src/share/classes/overview-core.html
            -sourcepath /java/pubs/ws/1.5/src/share/classes


       Create a file named "packages" containing:

            com.mypackage1
            com.mypackage2
            com.mypackage3


       You would then run javadoc with:

         % javadoc @options @packages


   Example - Arg Files with Paths
       The argument files can have paths, but any filenames inside the files
       are relative to the current working directory (not path1 or path2):

         % javadoc @path1/options @path2/packages


   Example - Option Arguments
       Here's an example of saving just an argument to a javadoc option in an
       argument file. We'll use the -bottom option, since it can have a
       lengthy argument. You could create a file named "bottom" containing its
       text argument:

       bug or feature</a><br><br>Java is a trademark or registered trademark of
       Sun Microsystems, Inc. in the US and other countries.<br>Copyright 1993-2000 Sun
       Microsystems, Inc. 901 San Antonio Road,<br>Palo Alto, California, 94303, U.S.A.
       All Rights Reserved.</font>'


       Then run the Javadoc tool with:

         % javadoc -bottom @bottom @packages


       Or you could include the -bottom option at the start of the argument
       file, and then just run it as:

         % javadoc @bottom @packages

       doclet, see Running the MIF Doclet @

SIMPLE EXAMPLES
       You can run javadoc on entire packages or individual source files. Each
       package name has a corresponding directory name. In the following
       examples, the source files are located at /home/src/java/awt/*.java.
       The destination directory is /home/html.

   Documenting One or More Packages
       To document a package, the source files (*.java) for that package must
       be located in a directory having the same name as the package. If a
       package name is made up of several identifiers (separated by dots, such
       as java.awt.color), each subsequent identifier must correspond to a
       deeper subdirectory (such as java/awt/color). You may split the source
       files for a single package among two such directory trees located at
       different places, as long as -sourcepath points to them both -- for
       example src1/java/awt/color and src2/java/awt/color.

       You can run javadoc either by changing directories (with cd) or by
       using -sourcepath option. The examples below illustrate both
       alternatives.

          o Case 1 - Run recursively starting from one or more packages - This
            example uses -sourcepath so javadoc can be run from any directory
            and -subpackages (a new 1.4 option) for recursion. It traverses
            the subpackages of the java directory excluding packages rooted at
            java.net and java.lang. Notice this excludes java.lang.ref, a
            subpackage of java.lang).
              % javadoc -d /home/html -sourcepath /home/src -subpackages java -exclude java.net:java.lang

          To also traverse down other package trees, append their names to the
          -subpackages argument, such as java:javax:org.xml.sax.

          o Case 2 - Run on explicit packages after changing to the "root"
            source directory - Change to the parent directory of the
            fully-qualified package. Then run javadoc, supplying names of one
            or more packages you want to document:
              % cd /home/src/
              % javadoc -d /home/html java.awt java.awt.event

          o Case 3 - Run from any directory on explicit packages in a single
            directory tree - In this case, it doesn't matter what the current
            directory is. Run javadoc supplying -sourcepath with the parent
            directory of the top-level package, and supplying names of one or
            more packages you want to document:
              % javadoc -d /home/html -sourcepath /home/src java.awt java.awt.event

          o Case 4 - Run from any directory on explicit packages in multiple
            directory trees - This is the same as case 3, but for packages in
            separate directory trees. Run javadoc supplying -sourcepath with
            the path to each tree's root (colon-separated) and supply names of
            one or more packages you want to document. All source files for a
            given package do not need to be located under a single root
            directory -- they just need to be found somewhere along the
            sourcepath.
              % javadoc -d /home/html -sourcepath /home/src1:/home/src2 java.awt java.awt.event


       Result: All cases generate HTML-formatted documentation for the public
       and protected classes and interfaces in packages java.awt and
       java.awt.event and save the HTML files in the specified destination
       directory (/home/html). Because two or more packages are being
       generated, the document has three HTML frames -- for the list of
       packages, the list of classes, and the main class pages.

   Documenting One or More Classes
       The second way to run the Javadoc tool is by passing in one or more
       source files (.java). You can run javadoc either of the following two
       ways -- by changing directories (with cd) or by fully-specifying the
       path to the .java files. Relative paths are relative to the current
       directory. The -sourcepath option is ignored when passing in source
       files. You can use command line wildcards, such as asterisk (*), to
       specify groups of classes.

          o Case 1 - Changing to the source directory - Change to the
            directory holding the .java files. Then run javadoc, supplying
            names of one or more source files you want to document.
              % cd /home/src/java/awt
              % javadoc -d /home/html Button.java Canvas.java Graphics*.java
            This example generates HTML-formatted documentation for the
            classes Button, Canvas and classes beginning with Graphics.
            Because source files rather than package names were passed in as
            arguments to javadoc, the document has two frames -- for the list
            of classes and the main page.

          o Case 2 - Changing to the package root directory - This is useful
            for documenting individual source files from different subpackages
            off the same root. Change to the package root directory, and
            supply the source files with paths from the root.
              % cd /home/src/
              % javadoc -d /home/html java/awt/Button.java java/applet/Applet.java
            This example generates HTML-formatted documentation for the
            classes Button and Applet.

          o Case 3 - From any directory - In this case, it doesn't matter what
            the current directory is. Run javadoc supplying the absolute path
            (or path relative to the current directory) to the .java files you
            want to document.
              % javadoc -d /home/html /home/src/java/awt/Button.java /home/src/java/awt/Graphics*.java
            This example generates HTML-formatted documentation for the class
            Button and classes beginning with Graphics.


   Documenting Both Packages and Classes
       You can document entire packages and individual classes at the same
       time. Here's an example that mixes two of the previous examples. You
       can use -sourcepath for the path to the packages but not for the path
       to the individual classes.

         % javadoc -d /home/html -sourcepath /home/src java.awt /home/src/java/applet/Applet.java


       This example generates HTML-formatted documentation for the package
       java.awt and class Applet. (The Javadoc tool determines the package
       name for Applet from the package declaration, if any, in the
       Applet.java source file.)

REAL WORLD EXAMPLE
       The Javadoc tool has many useful options, some of which are more
       commonly used than others. Here is effectively the command we use to
       run the Javadoc tool on the Java platform API. We use 180MB of memory
       to generate the documentation for the 1500 (approx.) public and
       protected classes in the Java 2 Platform, Standard Edition, v1.2.

       The same example is shown twice -- first as executed on the command
       line, then as executed from a makefile. It uses absolute paths in the
       option arguments, which enables the same javadoc command to be run from
       any directory.

   Command Line Example
       This command line example is over 900 characters, which is too long for
       some shells, such as DOS. You can use a command line argument file (or
       write a shell script) to workaround this limitation.

       % javadoc -sourcepath /java/jdk/src/share/classes            \
           -overview /java/jdk/src/share/classes/overview.html      \
           -d /java/jdk/build/api                                   \
           -use                                                     \
           -splitIndex                                              \
           -windowtitle 'Java 2 Platform 5.0 API Specification'    \
           -doctitle 'Java<sup><font size="-2">TM</font></sup> 2 Platform 5.0 API Specification' \

       where packages is the name of a file containing the packages to
       process, such as java.applet java.lang. None of the options should
       contain any newline characters between the single quotes. (For example,
       if you copy and paste this example, delete the newline characters from
       the -bottom option.) See the other notes listed below.

   Makefile Example
       This is an example of a GNU makefile. For an example of a Windows
       makefile, see creating a makefile for Windows @
       http://java.sun.com/j2se/javadoc/faq/index.html#makefiles.

               -d /java/jdk/build/api             \   /* Sets destination directory     */
               -use                               \   /* Adds "Use" files               */
               -splitIndex                        \   /* Splits index A-Z               */

       NOTES

          o If you omit the -windowtitle option, the Javadoc tool copies the
            doc title to the window title. The -windowtitle text is basically
            the same as the -doctitle but without HTML tags, to prevent those
            tags from appearing as raw text in the window title.

          o If you omit the -footer option, as done here, the Javadoc tool
            copies the header text to the footer.

          o Other important options you might want to use but not needed in
            this example are -classpath and -link.


TROUBLESHOOTING
   General Troubleshooting
          o Javadoc FAQ - Commonly-encountered bugs and troubleshooting tips
            can be found on the Javadoc FAQ @
            http://java.sun.com/j2se/javadoc/faq/index.html#B

          o Bugs and Limitations - You can also see some bugs listed at
            Important Bug Fixes and Changes @
            http://java.sun.com/j2se/1.5.0/fixedbugs/index.html.

          o Version number - See version numbers.

          o Documents only legal classes - When documenting a package, javadoc
            only reads files whose names are composed of legal class names.
            You can prevent javadoc from parsing a file by including, for
            example, a hyphen "-" in its filename.


   Errors and Warnings
       Error and warning messages contain the filename and line number to the
       declaration line rather than to the particular line in the doc comment.

          o "error: cannot read: Class1.java" the Javadoc tool is trying to
            load the class Class1.java in the current directory. The class
            name is shown with its path (absolute or relative), which in this
            case is the same as ./Class1.java.


ENVIRONMENT
          CLASSPATH
             Environment variable that provides the path which javadoc uses to
             find user class files. This environment variable is overridden by
             the -classpath option. Separate directories with a colon, for
             example:
