    First it may be instructive for you to tell us your thoughts on the matter. If you're not sure, consider walking through the code line by line as if you're the Java Virtual Machine and were executing the code yourself. If you run into a for loop, then loop that many times, changing your for loop index as you loop. This may not only provide you with your answer, but some good insights into how Java works as well.

    Edit: why the H did you re-post the same question that you've already posted previously? You didn't even read or follow Norm's recommendations. If your goal is to annoy us, congratulations, you've succeeded.

    That code will not produce that output. Check your code and post again. Put [code=java] before your code and [/code]after your code.

    Dont forget to read the forum rules to avoid "annoying" people.
