PMD scans Java source code and looks for potential problems like:
<ul>
 <li>Possible bugs - empty try/catch/finally/switch statements</li>
 <li>Dead code - unused local variables, parameters and private methods</li>
 <li>Suboptimal code - wasteful String/StringBuffer usage</li>
 <li>Overcomplicated expressions - unnecessary if statements, for loops that could be while loops</li>
 <li>Duplicate code - copied/pasted code means copied/pasted bugs</li>
</ul>
You can <a href="http://sourceforge.net/project/showfiles.php?group_id=56262">download everything from here</a>, and you can get an overview of all the rules at the <a href="rules/index.html">rulesets index</a> page.
PMD is <a href="integrations.html">integrated</a> with JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, CodeGuide, NetBeans/Sun Java Studio Enterprise/Creator, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs.
