How to stop Thread

Thread.stop()是一个不建议使用的方法。

 

 Thread in Java will stop once run() method finished. Another important point is that you can not restart a Thread which run() method has finished already , you will get an IllegalStateException.
所以正确让一个线程stop的方式是使用一个volatile变量来控制。

public class StoppableThread extends Thread {

   private volatile boolean stop = false;

   public void stopGracefully() {
     stop = true;
   }

   public void run() {
          while (!stop) {
       // long running action - finished will be true once work is done
     }
   }
}
