How to schedule a periodic task in Java?

Question

I need to schedule a task to run in at fixed interval of time. How can I do this with support of long intervals (for example on each 8 hours)?

I'm currently using java.util.Timer.scheduleAtFixedRate. Does java.util.Timer.scheduleAtFixedRate support long time intervals?

Answer 1

Use a ScheduledExecutorService:

 private final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);  scheduler.scheduleAtFixedRate(yourRunnable, 8, 8, TimeUnit.HOURS);
