    Hello Sarah-Perkin.

    Welcome to the Java Programming Forums

    What are you trying to achieve exactly?

    The only loop I can see in your code is a 'while' loop so if you want to add a loop within a loop, you can add another loop there.
    Please use [highlight=Java] code [/highlight] tags when posting your code.
