例子 (Example)

以下示例显示了java.lang.Thread.interrupt（）方法的用法。

package cn.xnip;
import java.lang.*;
public class ThreadDemo implements Runnable {
   Thread t;
   ThreadDemo() {
      t = new Thread(this);
      System.out.println("Executing " + t.getName());
      // this will call run() fucntion
      t.start();
      // interrupt the threads
      if (!t.interrupted()) {
         t.interrupt();
      }
      // block until other threads finish
      try {  
         t.join();
      } catch(InterruptedException e) {}
   }
   public void run() {
      try {       
         while (true) {
            Thread.sleep(1000);
         }
      } catch (InterruptedException e) {
      System.out.print(t.getName() + " interrupted:");
      System.out.println(e.toString());
      }
   }
   public static void main(String args[]) {
      new ThreadDemo();
      new ThreadDemo();
   }
} 

让我们编译并运行上面的程序，这将产生以下结果 -

Executing Thread-0
Thread-0 interrupted:java.lang.InterruptedException: sleep interrupted
Executing Thread-1
Thread-1 interrupted:java.lang.InterruptedException: sleep interrupted
