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

    Also copy the full text of the error messages and paste it here. It should show where the errors happened
    If you don't understand my answer, don't ignore it, ask a question.
