此方法返回线程组的名称。
示例
package com.yiibai.threadgroup;
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());
}
}
执行上面示例代码，得到以下结果：
Thread-1 is running
First threadGroup's name: Parent thread
Second threadGroup's name: Child thread
Thread-2 is running
