Java Threads -- Perpetual Loop in Swing Event Dispatch Thread

I have a SwingWorker with the implementation:

public Void doInBackground() throws InterruptedException
{
     while (true)
     {
            while(_update)
            {

            }
     }
}

If _update is set to false, is it safe to let the EDT perpetually go on a loop? Or should I let it sleep every second?

-- EDIT

It looks like I'm not using SwingWorker as it's supposed to be used. Thanks all. I'll stick to creating SwingWorkers as I need them.

Solution

  • It is not safe to let the Event Dispatch Thread go in a loop.

    The event dispatch thread is needed to provide user interaction with the application. If you want an event to go off every few seconds, you should put it, or another copy of it, back on the event queue each time it has completed.
