| Modifier and Type | Method and Description | 
|---|---|
<V> ScheduledFuture<V> | 
ScheduledThreadPoolExecutor.schedule(Callable<V> callable,
        long delay,
        TimeUnit unit)  | 
<V> ScheduledFuture<V> | 
ScheduledExecutorService.schedule(Callable<V> callable,
        long delay,
        TimeUnit unit)
Creates and executes a ScheduledFuture that becomes enabled after the
 given delay.

ScheduledExecutorService.schedule(Runnable command,
        long delay,
        TimeUnit unit)
Creates and executes a one-shot action that becomes enabled
 after the given delay.

ScheduledFuture<?> | 
ScheduledThreadPoolExecutor.scheduleAtFixedRate(Runnable command,
                   long initialDelay,
                   long period,
                   TimeUnit unit)  | 
ScheduledFuture<?> | 
ScheduledExecutorService.scheduleAtFixedRate(Runnable command,
                   long initialDelay,
                   long period,
                   TimeUnit unit)
Creates and executes a periodic action that becomes enabled first
 after the given initial delay, and subsequently with the given
 period; that is executions will commence after
  
initialDelay then initialDelay+period, then
 initialDelay + 2 * period, and so on. | 
ScheduledFuture<?> | 
ScheduledThreadPoolExecutor.scheduleWithFixedDelay(Runnable command,
                      long initialDelay,
                      long delay,
                      TimeUnit unit)  | 
ScheduledFuture<?> | 
ScheduledExecutorService.scheduleWithFixedDelay(Runnable command,

                      long delay,
                      TimeUnit unit)
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.
