Java ThreadGroup getName()用法及代碼示例

public final String getName()

class NewThread extends Thread 
{
    NewThread(String threadname, ThreadGroup tg)
    {
        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());
    }
}

First threadGroup's name:Parent thread
Thread-1 is running
Second threadGroup's name:Child thread
Thread-2 is running
