            }
            catch (InterruptedException ex) {
                System.out.println("Exception encounterted");}
        }
        System.out.println(Thread.currentThread().getName() +
                " finished executing");
    }
    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");
    }
}

输出结果为：

Thread-1 finished executing
Thread-2 finished executing
child thread destroyed
Parent thread destroyed
