I dunno how to create to create a math tutor. It is similiar to the console based math tutor you created earlier in the year. The applet will have two button. A new problem button, and a check answer button. If the user clicks on new problem, a new problem will be displayed in the problem label.

Components:
newProblem - a button that presents the user with a new
                problem when clicked.
checkAnswer - a button that checks the user's answer with
                the correct answer. If the answer is correct,
                displays "Good Job!". If the answer is incorrect,
                displays "Nice try, the answer is " and the correct
                answer
problem - Label containing the problem
answer - Label containing the answer message
userInput - TextField for the user to type an answer into. If the
                users hits enter, the answer should display.

The arithmatic expression can consist of integers between 0-20 and
(+, -, /, *). Use a random number generator for this.
It generates + = 1 - = 2 / = 3 * = 4


Can anybody write it so I can see how it works? Thanks

    public void actionPerformed(ActionEvent thisEvent)

        int Penter = Integer.parseInt(Ianswer.getText());

        if (e.getSource() == NewProb)

    public void problem()
    {
        int1 = ((int)Math.ceil(20 * Math.random()));
        int2 = ((int)Math.ceil(20 * Math.random()));

This is what I wrote, what else do I need?
