Question: What parts of a java class does javadoc create documentation for?


Answer: the set of heading lines of public methods

i.e. the headers of the public method definitions

as well as the heading of the class itself

and any public variables.



The set of public method headings makes up what is known as

the interface or the behaviour of the class - i.e. its functional abstraction.

Only public classes, methods and instance variables are documented by javadoc.






Question: What does a javadoc web page look like?


Answer:  For an example of a class and its javadoc html page click here.





 Question: How do I run javadoc?


Answer:  To run javadoc, assuming the Java SDK is located here:




 and assuming the file is in C:\temp


 Click on the Start button on the desktop

 Select Run

 Browse for this file:



 and in the Run textbox add the text exactly as here:


 C:\j2sdk1.4.2_01\bin\javadoc.exe  -d  C:\temp  C:\temp\


 and click on OK to run.



 IMPORTANT NOTE: if you installed java to the Program Files folder,

 for "Program Files" substitute "Progra~1" in the path, e.g.:

 C:\Progra~1\Java\jdk1.6.0_02\bin\javadoc.exe -d c:\temp C:\temp\



 The "-d c:\temp" is a javadoc flag specifying that the destination

 folder to write the html documentation files to, is C:\temp


 When you supply a .java file name to javadoc, you must give the full path,

 e.g. C:\temp\
