Java 实例 – 中断线程

以下实例演示了如何使用interrupt()方法来中断线程并使用 isInterrupted() 方法来判断线程是否已中断：

public class Main extends Object 
implements Runnable {
   public void run() {
      try {
         System.out.println("in run() - 将运行 work2() 方法");
         work2();
         System.out.println("in run() - 从 work2() 方法回来");
      }
      catch (InterruptedException x) {
         System.out.println("in run() - 中断 work2() 方法");
         return;
      }
      System.out.println("in run() - 休眠后执行");
      System.out.println("in run() - 正常离开");
   }
   public void work2() throws InterruptedException {
      while (true) {
         if (Thread.currentThread().isInterrupted()) {
            System.out.println("C isInterrupted()=" + Thread.currentThread().isInterrupted());
            Thread.sleep(2000);
            System.out.println("D isInterrupted()=" + Thread.currentThread().isInterrupted());
         }
      }
   }
   public void work() throws InterruptedException {
      while (true) {
         for (int i = 0; i

以上代码运行输出结果为：

in run() - 将运行 work2() 方法
in main() - 中断其他线程
in main() - 离开
C isInterrupted()=true
in run() - 中断 work2() 方法
