Error - Exit Timer - Please help

[Mykd]

Hi
I get the following errors when I changed something - I don't know what, but these occur now.

Exception in thread "AWT-EventQueue-0" java.lang.StackOverflowError

at ExitJoke.<init>(ExitJoke.java:43) <-- Keeps repeating itself over and over

I had changed something, because befor I did it would keep repeating the exit screen without stopping, then eventually freezing the computer because some many screens were open at once. Here's the code.

import java.util.Timer;
   import java.util.TimerTask;
/**

public class ExitJoke extends javax.swing.JFrame {

 Timer timer;

       public ExitJoke ( int seconds ) {
         timer = new Timer ( ) ;
         timer.schedule ( new RemindTask ( ) , seconds*1000 ) ;
      }

       class RemindTask extends TimerTask {
          public void run ( ) {

            timer.cancel ( ) ; //Terminate the timer thread
          
         }
      }
     
      {

         new ExitJoke ( 5 ) ;//Time in seconds.

 System.exit(0);
      }

    /** Creates new form ExitJoke */
    public ExitJoke() {
        initComponents();
    }                      


        public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new ExitJoke().setVisible(true);
            }
        });
    }

    // Variables declaration - do not modify                     
    private javax.swing.JButton btnJoke;
    private javax.swing.JPanel jPanel1;
    // End of variables declaration                   

}

I didn't include the 'Generated Code' as I have not touched it, and its very long :P

L24-29 this is initialization
When you creates (in main method) new instance of ExitJoke the first executed code is L24-29. L26 here is "new ExitJoke", this executes code in L24.
Then your program work in loop L26-L24-L26....
Move code L24-29 to end of main constructor

Thank you, it works fine now :)
