title: Java Multithreading - Best practice
body: <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>
