    there is a wrong but I don't find
    Please explain. Copy the contents of the window and paste it here that shows what you are asking about.

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

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    One problem I see: Use the equals() method to compare the contents of String objects, not the == operator.
    If you don't understand my answer, don't ignore it, ask a question.
