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
 */
 
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
