• Java 实例 - 获取所有线程

    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
