    Please wrap your code in the
    [highlight=java][/highlight] tags to get the formatting

    Define don't know how it works. I presume this is not your code...then study the lines in the code, step through it with a debugger, or add some println's to evaluate how variables change.

    The user presumably means that the code works, but they don't know the logic or it or why it is what it is.

    The game goes on forever. You don't seem to have a thing that will end it.
