Examples of java.util.concurrent.ScheduledExecutorService.schedule()

java.util.concurrent.ScheduledExecutorService.schedule()
Creates and executes a one-shot action that becomes enabled after the given delay. @param command the task to execute @param delay the time from now to delay execution @param unit the time unit of the delay parameter @return a ScheduledFuture representing pending completion ofthe task and whose {@code get()} method will return{@code null} upon completion @throws RejectedExecutionException if the task cannot bescheduled for execution @throws NullPointerException if command is null
