  74 .SH DESCRIPTION
  75 .PP
  76 The \f[CB]javadoc\f[R] tool parses the declarations and documentation
  77 comments in a set of Java source files and produces corresponding HTML
  78 pages that describe (by default) the public and protected classes,
  79 nested classes (but not anonymous inner classes), interfaces,
  80 constructors, methods, and fields.
  81 You can use the \f[CB]javadoc\f[R] tool to generate the API documentation
  82 or the implementation documentation for a set of source files.
  83 .PP
  84 You can run the \f[CB]javadoc\f[R] tool on entire packages, individual
  85 source files, or both.
  86 When documenting entire packages, you can use the \f[CB]\-subpackages\f[R]
  87 option either to recursively traverse a directory and its
  88 subdirectories, or to pass in an explicit list of package names.
  89 When you document individual source files, pass in a list of Java source
  90 file names.
  91 See \f[B]javadoc Overview\f[R]
  92 [https://www.oracle.com/pls/topic/lookup?ctx=en/java/javase/11/tools&id=JSJAV\-GUID\-7A344353\-3BBF\-45C4\-8B28\-15025DDCC643]
  93 in Java Platform, Standard Edition Javadoc Guide for information about
  94 using the \f[CB]javadoc\f[R] tool.
  95 .SH CONFORMANCE
  96 .PP
  97 The standard doclet does not validate the content of documentation
  98 comments for conformance, nor does it attempt to correct any errors in
  99 documentation comments.
 100 Anyone running javadoc is advised to be aware of the problems that may
 101 arise when generating non\-conformant output or output containing
 102 executable content, such as JavaScript.
 103 The standard doclet does provide the \f[CB]doclint\f[R] feature to help
 104 developers detect common problems in documentation comments; but it is
 105 also recommended to check the generated output with any appropriate
 106 conformance and other checking tools.
 107 .PP
 108 For more details on the conformance requirements for HTML5 documents,
 109 see \f[B]Conformance requirements\f[R]
 110 [https://www.w3.org/TR/html5/infrastructure.html#conformance\-requirements]
 111 in the HTML5 Specification.

 161 .B \f[CB]\-breakiterator\f[R]
 162 Computes the first sentence with \f[CB]BreakIterator\f[R].
 163 The first sentence is copied to the package, class, or member summary
 164 and to the alphabetic index.
 165 The \f[CB]BreakIterator\f[R] class is used to determine the end of a
 166 sentence for all languages except for English.

 172 Breakiterator sentence\-break algorithm \-\-\- Stops at a period,
 173 question mark, or exclamation point followed by a space when the next
 174 word starts with a capital letter.
 175 This is meant to handle most abbreviations (such as "The serial no.
 176 is valid", but will not handle "Mr.\ Smith").

 184 Generates output by using an alternate doclet.

 186 This doclet defines the content and formats the output.
 187 If the \f[CB]\-doclet\f[R] option isn\[aq]t used, then the
 188 \f[CB]javadoc\f[R] tool uses the standard doclet for generating the
 189 default HTML format.
 190 This class must contain the \f[CB]start(Root)\f[R] method.
 191 The path to this starting class is defined by the \f[CB]\-docletpath\f[R]
 192 option.
 193 .RS
 194 .RE
 195 .TP
 196 .B \f[CB]\-docletpath\f[R] \f[I]path\f[R]
 197 Specifies where to find doclet class files (specified with the
 198 \f[CB]\-doclet\f[R] option) and any JAR files it depends on.
 199 If the starting class file is in a JAR file, then this option specifies
 200 the path to that JAR file.
 201 You can specify an absolute path or a path relative to the current
 202 directory.
 203 If \f[CB]classpathlist\f[R] contains multiple paths or JAR files, then
 204 they should be separated with a colon (\f[CB]:\f[R]) on Oracle Solaris and
 205 a semi\-colon (\f[CB];\f[R]) on Windows.

 213 from the list formed by \f[CB]\-subpackages\f[R].
 214 It excludes those packages even when they would otherwise be included by
 215 some earlier or later \f[CB]\-subpackages\f[R] option.

 268 runs the \f[CB]javadoc\f[R] tool.
 269 For example, if you must ensure that the system sets aside 32 MB of
 270 memory in which to process the generated documentation, then you would
 271 call the \f[CB]\-Xmx\f[R] option as follows:
 272 \f[CB]javadoc\ \-J\-Xmx32m\ \-J\-Xms32m\ com.mypackage\f[R].
 273 Be aware that \f[CB]\-Xms\f[R] is optional because it only sets the size
 274 of initial memory, which is useful when you know the minimum amount of
 275 memory required.

 305 Otherwise, the navigation bars appear in English.
 306 This is the only command\-line option that depends on order.
 307 .PP
 308 Specifying a locale causes the \f[CB]javadoc\f[R] tool to choose the
 309 resource files of that locale for messages such as strings in the
 310 navigation bar, headings for lists and tables, help file contents,
 311 comments in the \f[CB]stylesheet.css\f[R] file, and so on.
 312 It also specifies the sorting order for lists sorted alphabetically, and
 313 the sentence separator to determine the end of the first sentence.

 748 documentation and should not be modified by the user.
 749 .PP
 750 When you use the \f[CB]javadoc\f[R] tool to document packages, it uses the
 751 \f[CB]package\-list\f[R] file to determine the packages declared in an
 752 API.
 753 When you generate API documents for modules, the \f[CB]javadoc\f[R] tool
 754 uses the \f[CB]element\-list\f[R] file to determine the modules and
 755 packages declared in an API.
 756 .PP
 757 The \f[CB]javadoc\f[R] tool reads the names from the appropriate list file
 758 and then links to the packages or modules at that URL.

 760 When the \f[CB]javadoc\f[R] tool runs, the \f[I]url\f[R] value is copied
 761 into the \f[CB]<A\ HREF>\f[R] links that are created.
 762 Therefore, \f[I]url\f[R] must be the URL to the directory and not to a
 763 file.
 764 .PP
 765 You can use an absolute link for \f[I]url\f[R] to enable your documents
 766 to link to a document on any web site, or you can use a relative link to
 767 link only to a relative location.
 768 If you use a relative link, then the value you pass in should be the
 769 relative path from the destination directory (specified with the
 770 \f[CB]\-d\f[R] option) to the directory containing the packages being
 771 linked to.
 772 When you specify an absolute link, you usually use an HTTP link.
 773 However, if you want to link to a file system that has no web server,
 774 then you can use a file link.
 775 Use a file link only when everyone who wants to access the generated
 776 documentation shares the same file system.
 777 In all cases, and on all operating systems, use a slash as the
 778 separator, whether the URL is absolute or relative, and \f[CB]https:\f[R],

 825 or modules, you can run the \f[CB]javadoc\f[R] tool again on a smaller set
 826 of changed packages or modules, so that the updated files can be
 827 inserted back into the original set.
 828 .PP
 829 For example, the \f[CB]\-linkoffline\f[R] option takes two arguments.
 830 The first is for the string to be embedded in the \f[CB]<a\ href>\f[R]

1058 Specifies single argument custom tags.
1059 For the \f[CB]javadoc\f[R] tool to spell\-check tag names, it is important
1060 to include a \f[CB]\-tag\f[R] option for every custom tag that is present
1061 in the source code, disabling (with \f[CB]X\f[R]) those that aren\[aq]t
1062 being output in the current run.
1063 The colon (\f[CB]:\f[R]) is always the separator.
1064 The \f[CB]\-tag\f[R] option outputs the tag heading, \f[I]header\f[R], in
1065 bold, followed on the next line by the text from its single argument.
1066 Similar to any block tag, the argument text can contain inline tags,
1067 which are also interpreted.

1069 \f[CB]\@return\f[R] and \f[CB]\@author\f[R] tags.

1132 The page describes what packages, classes, methods, constructors and

1134 Given class C, things that use class C would include subclasses of C,
1135 fields declared as C, methods that return C, and methods and
1136 constructors with parameters of type C.
1137 For example, you can look at the Use page for the \f[CB]String\f[R] type.
1138 Because the \f[CB]getName\f[R] method in the \f[CB]java.awt.Font\f[R] class
1139 returns type \f[CB]String\f[R], the \f[CB]getName\f[R] method uses
1140 \f[CB]String\f[R] and so the \f[CB]getName\f[R] method appears on the Use
1141 page for \f[CB]String\f[R].
1142 This documents only uses of the API, not the implementation.
1143 When a method uses \f[CB]String\f[R] in its implementation, but
