以下实例演示了如何使用 getName() 方法获取所有正在运行的线程：
Main.java 文件
public class Main extends Thread {
public static void main(String[] args) {
Main t1 = new Main();
t1.setName("thread1");
t1.start();
ThreadGroup currentGroup =
Thread.currentThread().getThreadGroup();
int noThreads = currentGroup.activeCount();
Thread[] lstThreads = new Thread[noThreads];
currentGroup.enumerate(lstThreads);
for (int i = 0; i < noThreads; i++)
System.out.println("线程号：" + i + " = " + lstThreads[i].getName());
}
}
以上代码运行输出结果为：
线程号：0 = main
线程号：1 = thread1暂无回复。
