    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    What do you mean by "stop"?
    If you don't understand my answer, don't ignore it, ask a question.

    I want the program to suspend execution so I can examine the variables at that point,

    Sorry, I missed that this was a question about using a debugger. I've never used one in a java program.
