        for (int i = 0; i < 10; i++) 
        {
            try
            {
                Thread.sleep(10);
            }
            catch (InterruptedException ex) 
            {
              System.out.println(Thread.currentThread().getName()
                                   + " interrupted");
            }
        }
        System.out.println(Thread.currentThread().getName() + 
             " completed executing");
    }
} 
public class ThreadGroupInterruptExp
{
    public static void main(String arg[]) throws InterruptedException,
        SecurityException
    {
        // creating the thread group
        ThreadGroup tg1 = new ThreadGroup("Parent thread");
        ThreadGroup tg2 = new ThreadGroup(tg1, "child thread");
        
        // creating a thread 
        NewThread t1 = new NewThread("Thread-1", tg1);
        System.out.println(t1.getName() + " starts");
        t1.start();
        
        // interrupting thread group
        tg1.interrupt();
        
        // creating another thread 
        NewThread t2 = new NewThread("Thread-2", tg1);
        System.out.println(t2.getName() + " starts");
        t2.start();
    }
}
