pmd-jdk14

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
