Doclets: Decipher and Document Java Code Easily

Trying to understand the logic of an unfamiliar Java project can be taxing. Learning the project's code is even more difficult when there is no knowledge transfer from the developer(s) who developed it. Increasingly, this is becoming a common task for developers, which isn't necessarily bad news because it provides a great opportunity for job security. A developer becomes indispensable when he or she is the knowledge source for existing projects. Doclets, a new addition to Java SE 6, is very handy for reviewing existing source code and mastering the logic behind it. Doclet is a starting class for defining the entry point methods of the package com.sun.javadoc.
