Btw, you can also incorporate gibson's class into the code you PMed me. That is, if you know how to instantiate objects, given the correct constructor and make calls to the class's methods. His code can make the concept of what you're trying to accomplish clearer via its OO characteristics.

I'll get you started on one integer.

Code:

    ...
    String sOne = JOptionPane.showInputDialog(null,
        "Enter Integer 1",
        "Input Dialog",
        JOptionPane.QUESTION_MESSAGE);

    ...
    MathData md = new MathData(sOne, ......);
    JOptionPane.showMessage(null, md.findSum());
    ...

You've got less than an hour... get crackin!
