What is a Java ScheduledExecutorService?

What is a Java ScheduledExecutorService?

The ScheduledExecutorService is part of the Java Concurrency framework that allows you to schedule tasks to run after a given delay or to execute periodically.

How do I create a ScheduledExecutorService?

You can create a ScheduledExecutorService using the Executors factory class, like this: ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);.

Can you give me an example of scheduling a task?

Sure! You can schedule a task like this: scheduler.schedule(() -> System.out.println("Task executed"), 5, TimeUnit.SECONDS); This will execute the task after 5 seconds.

What if I want to run a task repeatedly?

You can use the scheduleAtFixedRate method. For example: scheduler.scheduleAtFixedRate(() -> System.out.println("Repeating task"), 0, 10, TimeUnit.SECONDS); This runs the task every 10 seconds.
