How to stop a task in ScheduledThreadPoolExecutor once I think it's completed

Question

I have a ScheduledThreadPoolExecutor with which I schedule a task to run at a fixed rate. I want the task to be running with a specified delay for a maximum of say 10 times until it "succeeds". After that, I will not want the task to be retried. So basically I'll need to stop running the scheduled task when I want it to be stopped, but without shutting down the ScheduledThreadPoolExecutor. Any idea how I'd do that?

Here's some pseudocode -

public class ScheduledThreadPoolExecutorTest {   public static ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(15);  // no multiple instances, just one to serve all requests    class MyTask implements Runnable   {     private int MAX_ATTEMPTS = 10;     public void run()     {       if(++attempt <= MAX_ATTEMPTS)       {         doX();         if(doXSucceeded)         {           //stop retrying the task anymore         }       }       else       {          //couldn't succeed in MAX attempts, don't bother retrying anymore!       }     }   }    public void main(String[] args)   {     executor.scheduleAtFixedRate(new ScheduledThreadPoolExecutorTest().new MyTask(), 0, 5, TimeUnit.SECONDS);   } }

run this test, it prints 1 2 3 4 5 and stops

public class ScheduledThreadPoolExecutorTest {     static ScheduledThreadPoolExecutor executor = new ScheduledThreadPoolExecutor(15); // no     static ScheduledFuture<?> t;      static class MyTask implements Runnable {         private int attempt = 1;          public void run() {             System.out.print(attempt + " ");             if (++attempt > 5) {                 t.cancel(false);             }         }     }      public static void main(String[] args) {         t = executor.scheduleAtFixedRate(new MyTask(), 0, 1, TimeUnit.SECONDS);     } }
