i have an applet and i want to do this :-
when the button in it is pressed :-
in the actionperformed of the button i want to set a flag to true;

another method must somehow know that the flag is set and that method
must start executing

so lemme tell u what i did :-
in the init() of the applet i gave
Thread t = new Thread(this); thread.start()

then in run() i gave
try{ System.out.println("in run"); t.sleep(1000);
if(flag){methodname();System.out.println("in run if");
          t.sleep(1200);}
      }
      catch(Exception e){System.out.println("exception");}

but what happens in that "in run" is printed only once at the beginning
how do i accomplish what i want to ?
please need help !!!

public class XXX extends Applet implements ActionListener, Runnable {
     public void init() {
         Button b = new Button("Button");
         b.addActionListener(this);

         add(b);
     }

     public void actionPerformed(ActionEvent ae) {
         String ac = ae.getActionCommand();
         if (ac.equals("Button"))
             new Thread(XXX.this).start();
     }

     public void run() {
         while (???) { // while some condition is true, eg true
             // do whatever
             // if you want to sleep in the thread, use Thread.sleep()
             // Thread.sleep() is a static method that sleeps the
             // currently running thread
         }
         // when condition isn't true the thread will end
     }
