Submits 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.

- command
- IRunnable
the task to execute
- initialDelay
- Int64
the time to delay first execution
- delay
- Int64
the delay between the termination of one execution and the commencement of the next
- unit
- TimeUnit
the time unit of the initialDelay and delay parameters
Returns
a ScheduledFuture representing pending completion of the series of repeated tasks. The future's get() method will never return normally, and will throw an exception upon task cancellation or abnormal termination of a task execution.

Remarks
Submits 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.
The sequence of task executions continues indefinitely until one of the following exceptional completions occur: <ul> <li>The task is Future#cancel explicitly cancelled via the returned future. <li>Method #shutdown is called and the #getContinueExistingPeriodicTasksAfterShutdownPolicy policy on whether to continue after shutdown is not set true, or method #shutdownNow is called; also resulting in task cancellation. <li>An execution of the task throws an exception. In this case calling Future#get() get on the returned future will throw ExecutionException, holding the exception as its cause. </ul> Subsequent executions are suppressed. Subsequent calls to Future#isDone isDone() on the returned future will return true.
