你好，这句话有误了，根据interrupted方法的注释，应该是：如果连续两次调用interrupted()，第一次如果是true,第二次一定是false.因为此方法只会清除被中断的状态，而不会主动设置中断状态。

• Tests whether the current thread has been interrupted. The
  • interrupted status of the thread is cleared by this method. In
  • other words, if this method were to be called twice in succession, the
  • second call would return false (unless the current thread were
  • interrupted again, after the first call had cleared its interrupted
  • status and before the second call had examined it).
