    copied!<p>I'm having trouble at understanding out teachers' method of multithreading. Well, before showing both our examples I must say he's teaching a bunch of newbies (including me I guess ^.^) so he might have picked a method of multithreading that's easy to understand. Also, I'm not visiting his classes, but I've got his script which says the following:</p> <p>He's doing multithreading like this:</p> <pre><code>class MyThread implements Runnable { Thread t; MyThread() { t = new Thread(this, "Demo"); t.start(); } public void run() { try { for (int i = 5; i &gt; 0; i--) { System.out.println("Child-Thread:" + i); Thread.sleep(1000); } } catch (InterruptedException e) { System.out.println("Child interrupted"); } System.out.println("Child finished"); } } </code></pre> <p>I find it cleaner doing like this:</p> <pre><code>public class Aufg1 { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub MyThread t1 = new MyThread(1); ScheduledExecutorService executor = Executors.newScheduledThreadPool(5); executor.schedule(t1, 1, TimeUnit.SECONDS); } static class MyThread implements Runnable { int number; public MyThread(int number) { this.number = number; } @Override public void run() { // TODO Auto-generated method stub for (int i = 5; i &gt; 0; i--) { System.out.println("Thread " + number + ": " + i); } } } } </code></pre> <p>Don't bother why I used a Thread-Pool of size 5. I needed it for another exercise. Also, I could've used a ThreadPool for a single execution is this example.</p> <p>Is there a big difference? Is there an even cleaner way? I know there're some other methods to multithread as well, though I only showed one in here.</p> <p>Thanks!</p>
