    what problems are you having? Do you have any specific questions about the program?

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    So far, your code is reading in the data from the file.
    Try adding some output lines to check what it's doing.

    Follow the next step, getting the total value.

    (BTW What's in the data file?)
