Checkstyle ... must have for Java coders
What I like is that the package comes with ready made XML checkfiles for Sun Coding guideline. Add the job to Ant and you get a Javadoc type of HTML with codechanges you have to do to get your source compliant with the standard.
I don't believe in tools who do the job in your valuable source for ya.
Great program - especially when integrated with Ant
Checkstyle is a must-have for anyone developing Java software wanting consistency in their code and JavaDoc. It is especially useful when implemented as an Ant task - check it out!
An open, cross-platform journaling program.
A scientific plotting package.
