Java program hangs when in infinite loop

[S. Shree]

I have created a animation where balls fall from top to bottom. The balls are inside panels and the panels moves down. The top to down animation is done by run method of a class (Balls) extending Thread class. The animation starts at a click of button, but what happens is the buttons seems stuck and i cannot see the animation.

here is the code:

Balls[] b = new Balls[2];

while (true) {

b[0] = new Balls(0);
b[1] = new Balls(1);

b[0].start();
b[1].start();

// used the following lines so that the while loop waits before current threads are over
b[0].join();
b[1].join();
}

My overridden run() method is right, I load the ball image depending upon the instance variable numb and then use the repaint() method in the paintComponent() method.

Now, if I remove the while loop, it works perfectly fine, but I want it to run again and again and there is where it strucks. Please help!

usually you make a thread and the thread executes the while loop parallel to the application. what you are doing is executing the thread over and over in a while loop.

You should have to execute your thread(s) once and then in the thread do what is needed to be done "over and over again".
