    The code would be easier to understand if it were properly formatted. The statements should be indented for nested logic (ie inside loops) and there should be {}s around the code in each loop.

    Please Edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
