  如何检查线程是否已停止？
• 

  解决方案

  以下示例演示如何通过使用 isMoove() 方法检查线程是否已停止。

  
  public class Main {
     public static void main(String[] argv)throws Exception { 
        Thread thread = new MyThread();
        thread.start();
        
        if (thread.isMoove()) {
           System.out.println("Thread has not finished");
        } else {
           System.out.println("Finished");
        }
        long delayMillis = 5000; 
        thread.join(delayMillis);
        
        if (thread.isMoove()) {
           System.out.println("thread has not finished");
        } else {
           System.out.println("Finished");
        }
        thread.join();
     }
  }
  class MyThread extends Thread {
     boolean stop = false;
     public void run() {
        while (true) {
           if (stop) {
              return;
           }
        }
     }
  }
  

• 

  结果

  上面的代码示例将产生以下结果。

  
  Thread has not finished
  Finished
