pmd

Static analysis tool for Java source code

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
