PMD scans Java source code and looks for potential problems like:
- Possible bugs: empty try/catch/finally/switch statements
- Dead code: unused local variables, parameters and private methods
- Suboptimal code: wasteful String/StringBuffer usage
- Overcomplicated expressions: unnecessary if statements, for loops that could be while loops
- Duplicate code: copied/pasted code means copied/pasted bugs
PMD is integrated with JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, CodeGuide, NetBeans/Sun Java Studio Enterprise/Creator, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs.
