The schedule method you're using executes a one-shot action.

You need to use ScheduledExecutorService.scheduleWithFixedDelay:

Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next.

Try this:

scheduler.scheduleWithFixedDelay(new Runnable() {
        @Override
        public void run() {
          // your code
        }
    }, 3, 3, SECONDS);

Note the extra 3 in the method call as this methods expects four arguments.
