Stopping a looped method

[TyCox94]

I have a button that I want to "toggle". The button activates a looping method. I want to be able to stop the loop with the same button, or a different button if needed. For some reason the button freezes?

public void start() {
        //some code();
        start();
    }

Swing is single threaded: start a long task within the single thread (eg the EDT) - eg with the click of a button through an ActionListener - and it will lock up the user interface until said task is complete. Use a Thread, SwingWorker, or SwingTimer to do the work in parallel to the EDT. Google these for more information on each.
