Java: Scheduling a task in random intervals

Question

I am quite new to Java and I\'m trying to generate a task that will run every 5 to 10 seconds, so at any interval in the area between 5 to 10, including 10.

I tried

Answer 1

Create a new Timer for each task instead, like you already do: timer= new Timer();

And if you want to synchronize your code with your threaded tasks, use semaphores and not sleep(10000). This might work if you're lucky, but it's definitely wrong because you cannot be sure your task has actually finished.

Answer 2

try

public class Test1 {
    static Timer timer = new Timer();

    static class Task extends TimerTask {
        @Override
        public void run() {
            int delay = (5 + new Random().nextInt(5)) * 1000;
            timer.schedule(new Task(), delay);
            System.out.println(new Date());
        }

    }

    public static void main(String[] args) throws Exception {
        new Task().run();
    }
}
