super(tg, threadname);
start();
}
public void run()
{
System.out.println(Thread.currentThread().getName()+" is running");
}
}
public class ThreadGroupGetNameExp
{
public static void main(String arg[]) throws InterruptedException,
SecurityException, Exception
{
// creating the threadGroup
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("First threadGroup's name:" +t1.getThreadGroup().getName());
// creating another thread
NewThread t2 = new NewThread("Thread-2", tg2);
System.out.println("Second threadGroup's name:" +t2.getThreadGroup().getName());
}
}
输出:
First threadGroup's name:Parent thread Thread-1 is running Second threadGroup's name:Child thread Thread-2 is running
