how to start and stop the scheduledexecutorservice multiple times
<p>I am using ScheduledExecutorService, and after I call it's cancel method on scheduleFuture, I can't schedule a Runnable on it. Calling <code>scheduleAtFixedRate(runnable, INITIAL_DELAY, INTERVAL, TimeUnit.SECONDS)</code> after <code>cancel()</code>, nothing happens. Is there any way to restart the <code>ScheduledExecutorService</code> after <code>cancel()</code> method is called?</p>
