" 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");
}
}
