    Please edit your post and wrap your code with code tags:
    [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.

    And ask a question or describe what you need help with or don't understand. Like when my 3-year old would just point at something and grunt or whine, we'd say, "Use your words." Try that.
