Hi All,

I have a java swing app with different buttons and features. I need assistance in writing a thread to:
Have the java app timeout and exit the java app after three minutes of not pressing any buttons in the app.

Another words, if the app goes unused for 3 minutes then exit. (Not just at the start of the app, but at any time during the use of the app that three minures have gone by since they have clicked anything.

Thank you for you help in advance.

You can write a class e.g: Timer (see code snippet):

Then in main you can start it like this:
  Thread t = new Thread(new Timer());
   t.start ( );

In function "click" of each button that should keep application running you should call static method resetCounter()

Thats all ;-)
hope this helps
public class Timer implements Runnable {
  private static int max = 180;
 
  private static int counter = 0;
 
  /**
   * @see java.lang.Runnable#run()
   */
  public void run ( ) {
    while ( counter < max ) {
      // just keep running
      try {
        Thread.sleep ( 1000 );
        counter++;
        System.out.println ("---W--");
      }
      catch ( InterruptedException e ) {
        // won't handle
      }
    }
    System.exit ( 0 );
  }
 
  public static void resetCounter ( ) {
    counter = 0;
  }  
 
}
