Java线程池执行器

Question

I am doing a reminder application.

I have the jobs in the priority queue.

The sample job object is {job_id : 1001, epoch : 1514140200000} .

The task is to make the job execute in that epoch time.

I am planning to dequeue a job from the queue and assign a thread to it and schedule it to run in that epoch time. Is there a way to do it or is that the correct way to do?

Answer 1

If you want to do this via Java thread pools, see the ScheduledExecutorService: https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledExecutorService.html .

That has a nice sample, but basically you can schedule tasks to run at particular times or after a particular delay.

Libraries like Quartz (as someone notes) provide lots of other options.
