java - Stop a periodic task from within the task itself running in a ScheduledExecutorService

Question

Is there a nice way to stop the repetition of task from within the task itself when running in a ScheduledExecutorService?

Lets say, I have the following task:

Future<?> f = scheduledExecutor.scheduleAtFixedRate(new Runnable() {
    int count = 0;
    public void run() {
       System.out.println(count++);
       if (count == 10) {
           // ??? cancel self
       }
    }
}, 1, 1, TimeUnit.SECONDS);

From outside, it is easy to cancel via f.cancel(), but how can I stop the repetition at the specified place? (Passing the Future through an AtomicReference is not safe, because there is a potential window when the scheduleAtFixedRate returns f late and the variable is set late too, and the task itself might already run, seeing a null in the reference.)

Answer 1

When a repeating task throws an Exception or Error, it is placed in the Future and the task is not repeated again. You can throw a RuntimeException or Error of your choice.
