PMD – duplicate code finder

PMD – duplicate code finder
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
