          t1.start();
          ThreadGroup currentGroup =
          Thread.currentThread().getThreadGroup();
          int noThreads = currentGroup.activeCount();
          Thread[] lstThreads = new Thread[noThreads];
          currentGroup.enumerate(lstThreads);
          for (int i = 0; i < noThreads; i++)
          System.out.println("Thread No:" + i + " = "
          + lstThreads[i].getName());
