A java.util.concurrent.ScheduledExecutorService interface is a subinterface of ExecutorService interface, and supports future and/or periodic execution of tasks. ScheduledExecutorService Methods Sr.No. Method & Description 1 <V> ScheduledFuture<V> schedule(Callable<V> callable, long delay, TimeUnit unit)Creates and executes a ScheduledFuture that becomes enabled after the given delay. 2 ScheduledFuture<?> schedule(Runnable command, long delay, TimeUnit unit)Creates and executes a one-shot…

A java.util.concurrent.ExecutorService interface is a subinterface of Executor interface, and adds features to manage the lifecycle, both of the individual tasks and of the executor itself. ExecutorService Methods Sr.No. Method & Description 1 boolean awaitTermination(long timeout, TimeUnit unit)Blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current…

A java.util.concurrent.Executor interface is a simple interface to support launching new tasks. ExecutorService Methods Sr.No. Method & Description 1 void execute(Runnable command)Executes the given command at some time in the future. Example The following TestThread program shows usage of Executor interface in thread based environment. This will produce the following result. Output

A java.util.concurrent.atomic.AtomicReferenceArray class provides operations on underlying reference array that can be read and written atomically, and also contains advanced atomic operations.
