<p>PMD scans Java source code and looks for potential problems like:</p>
<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>
<p>You can <b><a href="http://sourceforge.net/project/showfiles.php?group_id=56262">download everything from here</a></b>, and you can get an overview of all the rules at the <a href="rules/index.html">rulesets index</a> page.</p>
