How to keep listening for tasks in executorservice

Question

Say I have a queue full of tasks which I need to submit to an executor service. I want to process them in parallel. That's cover.

private ExecutorService service = Executors.newFixedThreadPool(5);

I recive 20 tasks to be executed, and all of there are processed as I expected in groups of 5.

service.execute(tasks.poll());

But now I want to keep adding tasks to the queue and process them as I do now, but the service finish after the 20 original tasks.

How can I do this?

Answer 1

       executor.awaitTermination()

这将等待所有任务完成，这应该在executorl.shutdown（）之后使用
