This code makes the graphics object move through the JFrame, how do I do it such that, when a button is clicked, the graphics objects stop moving.

What Thread is this one. I'm hoping it's not the EDT, as it's pretty horrible to sleep on the EDT. But if it's not, then you're modifying variables you presumably use on the EDT, which might get tricky.

But the basic answer is- why don't you just have a boolean that indicates that the objects should be moving, check that in your above loop, and set it to false when you click the button? When it's false, exit the loop.

If you want help, you'll have to provide an SSCCE that demonstrates the problem. Otherwise we're just guessing at what you're doing.
