    If the OP is using an IDE such as NetBeans or Eclipse now might be a good time to learn how to use the debug feature. You can set your breakpoint anywhere you want in the code and the program will pause at that point. You can then use the buttons to step through the code and observe what variables change on each line. Debugger will become your best friend.
