public static void main(String arg[]) throws InterruptedException, SecurityException

{

// creating a ThreadGroup

ThreadGroup g1 = new ThreadGroup("Parent thread");

// creating a child ThreadGroup for parent ThreadGroup

ThreadGroup g2 = new ThreadGroup(g1, "child thread");

// creating a thread

Demo t1 = new Demo("Thread-1", g1);

// creating another thread

Demo t2 = new Demo("Thread-2", g1);

// block until other thread is finished

t1.join();

t2.join();

// destroying child thread

g2.destroy();

System.out.println(g2.getName() + " destroyed");

// destroying parent thread

g1.destroy();

System.out.println(g1.getName() + " destroyed");

}

}
