Question

I\'m making a game and i need to update the JProgressBar every 3 seconds. To do that i use a while loop. The problem is that my program freezes becuse of the while loop (i read

Answer 1

You will need to use threads for that. But be careful, and don't try to update the GUI component (JProgressBar) from a thread that does not own the progress bar.

You should use SwingUtilities.invokeLater to do that.

Answer 2

You should run your loop in an own Thread:

        new Thread( new Runnable() {
            @Override
            public void run()
            {
                resourceLoader (null);
            }}).start();

BTW: If you do not use the "String[] args" in the method there is no reason to have it declared in the method.

Answer 3

I'm not sure what you're trying to do with this program, but there you might want to investigate using a listener instead of rolling your own regular time interval. Also, if your while condition is simply true, it's probably a smell that there is a simpler way to implement the solution - messing with threads is playing with fire.
