    Default Re: No such method, help

    You left off the name of the method that the compiler could not find.
    Always copy the full text of the error message and paste it here.

    Check in the API doc for the class being used to see what methods are there and how to use them:
    Java Platform SE 7

    BTW The posted code is really UGLY with more than one statement on a line.
    If you don't understand my answer, don't ignore it, ask a question.
