How do you have a java applet repeat itself

Question

I have a Graphics lab in java that runs a applet with 7 different "slides" with the click of the mouse. After the seventh slide I need to find out how to run my whole applet over again from the first slide. I think it has something to do with a While loop or the repaint method but am unsure< Help!

Here is my code for a better

Answer 1

There are two simple solutions:

• as already suggested: simply reset your click counter
• instead of doing switch (numClicks) you could do use the modulo operation, in order to determine: is the counter a multiple of 1, 2, 3, 4, 5, or 6, and so on. For a multiple of 6, you call page7() ... and so on.

But: as so often, the real issue here is: UI examples are not a good way to learn Java. You see, you are lacking basic skills in Java!

Example: you are duplicating code all over the place. Your 7 page() methods are almost identical. You shouldn't worry how to enhance your code, but how to simplify it. Identify common patterns; and move them into specific methods. So that when you want to increase the Times font by 1, you only update 1 method, not 7.

Answer 2

If you're just trying to go back to the first slide, all you need is something that will reset numClicks to 0 when it is greater than the number of slides.

For example:

public boolean mouseDown(Event e, int x, int y)
{
    numClicks++;
    repaint();
    if (numClicks == 6) {
        numClicks = 0;
    }
    return true;
}

This perhaps isn't the best way to do it, but it should get the job done.
