How to stop the task scheduled in java.util.Timer class

I am using java.util.Timer class and I am using its schedule method to perform some task, but after executing it for 6 times I have to stop its task.

How should I do that?

Keep a reference to the timer somewhere, and use:

timer.cancel();
timer.purge();

to stop whatever it's doing. You could put this code inside the task you're performing with a static int to count the number of times you've gone around, e.g.

private static int count = 0;
public static void run() { count++; if (count >= 6) { timer.cancel(); timer.purge(); return; } ... perform task here ....
}

Either call cancel() on the Timer if that's all it's doing, or cancel() on the TimerTask if the timer itself has other tasks which you wish to continue.

You should stop the task that you have scheduled on the timer: Your timer:

Timer t = new Timer();
TimerTask tt = new TimerTask() { @Override public void run() { //do something };
};
t.schedule(tt,1000,1000);

In order to stop:

tt.cancel();
t.cancel(); //In order to gracefully terminate the timer thread

Notice that just cancelling the timer will not terminate ongoing timertasks.

timer.cancel(); //Terminates this timer,discarding any currently scheduled tasks.
timer.purge(); // Removes all cancelled tasks from this timer's task queue.

Terminate the Timer once after awake at a specific time in milliseconds.

Timer t = new Timer();
t.schedule(new TimerTask() { @Override public void run() { System.out.println(" Run spcific task at given time."); t.cancel(); } }, 10000);
