ScheduledExecutorService with variable delay

Question

Suppose I have a task that is pulling elements from a java.util.concurrent.BlockingQueue and processing them.

public void scheduleTask(int delay, TimeUnit ti         


        

Answer 1

scheduleWithFixedDelay(...) returns a RunnableScheduledFuture. In order to reschedule it, you might just cancel and reschedule it. To reschedule it, you may just wrap the RunnableScheduledFuture wit a new Runnable:

new Runnable() {
    public void run() {
        ((RunnableScheduledFuture)future).run();
    }
};
