    I dont know what is the error
    And neither do we. Please tell us. Does it compile? Are there exceptions? Does it run as expected?

    Please see Announcements - What's Wrong With My Code? for instructions on code tags formatting.

    I am allergic to clicking things. Please post the code to the forum in code tags.

    You will need to look at the program and see what it is doing. Use printlns or a debugger to monitor the values of variables. (Specifically those that control things related to the problem you see.)
    Verify the values are what you think they should be. If you can not find the problem, you will have to explain to us what it is doing, and what you would like for it to do instead, specifically. Generalized statements like "it is not winning" is not specific, and would force someone to try to read and understand what broken-code was supposed to do.
