Java Tools - Finding bugs, optimization and profiling

There a few tools for Java developers that can help us to be "better" programmers, (a bad programmer will allows be bad...). Finding bugs, optimization and profiling make part of a programmer day life, and why not using tools like these ones:


«FindBugs, a program wich uses static analysis to look for bugs in Java 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

PMD is integrated with JDeveloper, Eclipse, JEdit, JBuilder, BlueJ, CodeGuide, NetBeans/Sun Java Studio Enterprise/Creator, IntelliJ IDEA, TextPad, Maven, Ant, Gel, JCreator, and Emacs.»

«YourKit, LLC is a technology leader, creator of the most innovative and intelligent tools for profiling Java & .NET applications. The YourKit Java Profiler has been already recognized by the IT professionals and analysts as the best profiling tool.
