    Default Re: Bank Balance - while loop

    There are a few issues in your code.

    You need to initialize variables newBalance & deposit

    and char response = Y; should be char response = 'Y'; to get rid of this error although there are still issues here.

    In future, please put the highlight tags around your code and give an actual description of your problems.
    Please use [highlight=Java] code [/highlight] tags when posting your code.
