When should I use ScheduledExecutorService in Java?

What is ScheduledExecutorService in Java?

ScheduledExecutorService is an interface in Java that allows you to schedule tasks to run after a given delay or to execute periodically.

When should I use ScheduledExecutorService instead of Timer?

You should use ScheduledExecutorService when you need better thread management, flexibility, and the ability to handle exceptions more effectively than Timer.

Can you give me an example of how to use it?

Sure! You can create a ScheduledExecutorService instance and use the schedule method to run a task after a delay, like this:

ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
scheduler.schedule(() -> System.out.println("Task executed!"), 5, TimeUnit.SECONDS);
