Java 實(shí)例 - 獲取所有線程

Java 實(shí)例 Java 實(shí)例

以下實(shí)例演示了如何使用 getName() 方法獲取所有正在運(yùn)行的線程:

/*

 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("線程號(hào):" + i + " = " + lstThreads[i].getName());
   }
}

以上代碼運(yùn)行輸出結(jié)果為:

線程號(hào):0 = main
線程號(hào):1 = thread1
