Java threads : ExecutorService delay between threads

Question

I know the traditional way to delay a thread by using sleep method. My question is supposedly i have the following:

ExecutorService threadExecutor = Executors.newFixedThreadPool(5);  

Is there a way say by using ExecutorService class to have a delay between each threads without using sleep method? I mean is there a method in ExecutorService class for this purpose?

Answer 1

Do you mean something like

ScheduledExecutorService service = Executors.newScheduledThreadPool(5);

service.scheduleAtFixedRate(task, initialDelay, period, TimeUnit.MILLISECONDS);

If you want three tasks, 10 seconds apart you can do

service.execute(task1);
service.schedule(task2, 10, TimeUnit.SECONDS);
service.schedule(task3, 20, TimeUnit.SECONDS);
