Sorry here is the code.

public class MultipleThread implements Runnable
     Thread thread;
     String name;
     MultipleThread(String nam)
          this.name=nam;
          thread = new Thread(this,name);
          thread.start();
     public void run()
          try
               for (int i=1;i<=10;i++ )
                    Thread.sleep(1000);
                    System.out.println("Thread "+name+" "+i);
          catch (InterruptedException e)
               System.out.println(""+e);
     public static void main(String [] args)
          try
               MultipleThread t1=new MultipleThread("One");
               MultipleThread t2=new MultipleThread("Two");
               MultipleThread t3 =new MultipleThread("Three");
               //t1.join();
               //t2.join();
               //t3.join();
               for (int i=1;i<=10;i++ )
                    Thread.sleep(1000);
                    System.out.println("Parent Thread "+i);
          catch (InterruptedException e)
               System.out.println(" "+e);
}
