16. Example: IOTask class implementing the Runnable interface

• 
  public class IOTask implements Runnable
  {
      @Override
      public void run()
      {
          Thread ct = Thread.currentThread();
          System.out.println( ct.getName() + " started" );
          
          try
          {  
              // Sleep for 2 seconds to simulate an IO task
              // that takes a long time          
              Thread.sleep( 2000 );    
          }
          catch( InterruptedException ex )
          {
          }
  
          System.out.println( ct.getName() + " finished" );
      }
  }
