5.6退出循环的代码在git更新了，就是在catch时，增加一个Thread.currentThread().interrupt();

代码如下:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

public class RightWayStopThreadInProd implements Runnable {       @Override     public void run() {         while (true && !Thread.currentThread().isInterrupted()) {             System.out.println("go");             try {                 throwInMethod();             } catch (InterruptedException e) {                 Thread.currentThread().interrupt();                 //保存日志、停止程序                 System.out.println("保存日志");                 e.printStackTrace();             }         }     }       private void throwInMethod() throws InterruptedException {             Thread.sleep(2000);     }       public static void main(String[] args) throws InterruptedException {         Thread thread = new Thread(new RightWayStopThreadInProd());         thread.start();         Thread.sleep(1000);         thread.interrupt();     } }

  public class RightWayStopThreadInProd implements Runnable {
   
      @Override
      public void run() {
          while (true) {
              System.out.println("go");
              try {
                  throwInMethod();
              } catch (InterruptedException e) {
                  Thread.currentThread().interrupt();
                  //保存日志、停止程序
                  System.out.println("保存日志");
                  e.printStackTrace();
                  return;
              }
          }
      }
   
      private void throwInMethod() throws InterruptedException {
              Thread.sleep(2000);
      }
   
      public static void main(String[] args) throws InterruptedException {
          Thread thread = new Thread(new RightWayStopThreadInProd());
          thread.start();
          Thread.sleep(1000);
          thread.interrupt();
      }
  }
  1. 请问老师不重新设置interrupt标志位，直接return或者break结束也可以吧？
