Learn JavaDoc

Javadoc HTML documentaion is the industry standard for documentating Java source code.

Javadoc comments are embedded in Java source code using special Javadoc tags. A special software program created by Sun MicroSystems (who created Java) called the Javadoc Tool is run against your source code and thereby generates a set of HTML files called Javadocs.

Note that you may use HTML tags as well as Javadoc tags to document your source code. Javadoc files are HTML files. As such, they will use standard HTML tags as well.

Javadoc documentation separates the program's documentation from it's source code.

Sun's Javadoc Tool uses the Javadoc tags to strip the Javadoc comments from the source code and organize those Javadoc comments into hypertext files in a specific format established by Sun MicroSystems.

Because Java programmers are familiar with the format of Javadoc HTML files, programmers may read and understand this form of documentation more easily and rapidly than reading corresponding comments that are only embedded in Java source code.

Big Java

Peruse Cay Horstmann's summary of Javadoc documentation. Note that he explains how to generate HTML Javadoc documentation from the command line.

Horstmann, Cay (2006). Appendix K: Javadoc Summary. In Big Java (2nd Ed., 1149-1151). Hoboken, NJ: John Wiley & Sons, Inc.

Here is Horstmann's summary of Javadoc documentation from Appendix J of Horstmann's 3rd edition of Big Java, found with Kevin Lillis' course CSCI 195 Object Oriented Programming at St. Ambrose University, Davenport, Iowa Retrieved November 4, 2007, from http://web.sau.edu/LillisKevinM/csci195/2007Fall/slides/appJ/appJ.html

NCSU Tutorial
[csg] [web]

This excellent tutorial introduces JavaDoc documentation using the Eclipse IDE.

When generating Javadoc files using Eclipse, you will be asked for the location of the Javadoc Tool. Note that the Javadoc tool is found in the jdk (Java Development Kit) bin directory (Example: C:\Program Files\Java\jdk1.6.0_01\bin\javadoc.exe) and not the jre (Java Runtime Environment) bin directory (Example: C:\Program Files\Java\jre1.6.0_01\bin).

Incidentally, the term "bin" as in "bin directory" refers to the directory containing "binary" Java files, which are the executable and dynamic link library files containing the extension ".exe" or ".dll". These are in contrast to other types of files found in the lib (library), doc (documentation), demo (demonstration programs), and include (C language header files) directories.

Customize Javadocs
[csg] [web]

IBO requires that method preconditions and postconditions be documented.

This tutorial introduces three customized Javadoc tags:

@pre@post@invariant

Copy, paste and customize this (red) syntax for the taglet switches:
