Java - Running a thread twice [closed]

Answer 1

I would use another layer of abstraction. Use an ExecutorService.

Here is a simple example:

public static void main(String args[]) throws InterruptedException {
    final ExecutorService service = Executors.newCachedThreadPool();
    final class MyTask implements Runnable {

        @Override
        public void run() {
            System.out.println("Running my task.");
        }
    };
    for (int i = 0; i < 10; ++i) {
        service.submit(new MyTask());
    }
    service.shutdown();
    service.awaitTermination(1, TimeUnit.DAYS);
}

Just dump your task into the service as many times as you want.

The ExecutorService is a thread pool - it has a number of Threads that take tasks as they come. This removes the overhead of spawning new Threads because it caches them.
