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("Starting of Thread-1");
t1.start();
// this will suspend all the threads
tg1.suspend();
// creating another thread
NewThread t2 = new NewThread("Thread-2", tg2);
System.out.println("Starting of Thread-2");
t2.start();
// this will resume all the threads suspended by tg1
tg1.resume();
