    inshal: please don't hijack someone else's question. I have moved your question to its own thread, and Norm has added code tags so that the code retains its formatting. You will want to give us the details on what's wrong with your code including posting any and all error messages and any questions that you might have.

    Check that all the {s have a matching }
    and that all method definitions end (the ending }) before another method's definition starts.

    On windows: To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.
