2.  
3. Program :
4.  
5. class NewThread implements Runnable 
6. { 
7. String name;
8.  // name of thread Thread t;
9.  NewThread(String threadname)
10.  { 
11. name = threadname;
12. 
    
13. t = new Thread(this, name); 
14. System.out.println("New thread: " + t);
15.  t.start(); 
16. // Start the thread 
17. } // This is the entry point for thread.
18.  public void run() 
19. { 
20. try 
21. { 
22. for(int i = 5; i > 0; i--) 
23. { 
24. System.out.println(name + ": " + i);
25.  Thread.sleep(1000);
26.  } 
27. }
28.  catch (InterruptedException e)
29.  { 
30. System.out.println(name + "Interrupted");
31.  }
32.  System.out.println(name + " exiting."); 
33. }
34.  }
35.  class MultiThreadDemo 
36. {
37.  public static void main(String args[])
38.  {
39.  new NewThread("One"); // start threads new NewThread("Two"); new NewThread("Three");
40.  try 
41. { // wait for other threads to end Thread.sleep(10000);
42.  } 
43. catch (InterruptedException e)
44.  {
45.  System.out.println("Main thread Interrupted"); 
46. } 
47. System.out.println("Main thread exiting.");
48.  } 
49. }
