線程中斷 thread.interrupt()的用法

public class Main extends Thread{
   boolean stop = false;
   public static void main(String[] args) throws Exception {
      Thread thread = new Thread(new Main(),"My Thread2");
      System.out.println( "Starting thread..." );
      thread.start();
      Thread.sleep( 3000 );
      System.out.println( "Interrupting thread..." );
      thread.interrupt();
      System.out.println("線程是否中斷：" + thread.isInterrupted());
      Thread.sleep( 3000 );
      System.out.println("Stopping application..." );
   }
   public void run() {
      while(!stop){
         System.out.println( "My Thread is running..." );
         // 讓該循環持續一段時間，使上面的話打印次數少點
         long time = System.currentTimeMillis();
         while((System.currentTimeMillis()-time < 1000)) {
         }
         if(Thread.currentThread().isInterrupted()) {
            return;
         }
      }
      System.out.println("My Thread exiting under request..." );
   }
}
