My attitude toward debugging is decidedly non-Java, but I find the best thing to do is break your problem into small enough pieces that you can experiment with them rapidly in the REPL. For certain stuff that is hard to test in the repl (such as aspects of applet development for example and other things that depend on an environment in which they run), use print statements. Most debugger experiences I have had have in the end not offered much, and I have had better luck applying minimalist debugging techniques and critical thinking about the logic of problems.
