   * Interrupts this thread.
   *
   * <p> Unless the current thread is interrupting itself, which is
   * always permitted, the {@link #checkAccess() checkAccess} method
   * of this thread is invoked, which may cause a {@link
   * SecurityException} to be thrown.
   *
   * <p> If this thread is blocked in an invocation of the {@link
   * Object#wait() wait()}, {@link Object#wait(long) wait(long)}, or {@link
   * Object#wait(long, int) wait(long, int)} methods of the {@link Object}
   * class, or of the {@link #join()}, {@link #join(long)}, {@link
   * #join(long, int)}, {@link #sleep(long)}, or {@link #sleep(long, int)},
   * methods of this class, then its interrupt status will be cleared and it
   * will receive an {@link InterruptedException}.
如果线程正处在waiting状态，那么它的中断状态将被清除，并收到一个InterruptedException异常
   *
   * <p> If this thread is blocked in an I/O operation upon an {@link
   * java.nio.channels.InterruptibleChannel </code>interruptible
   * channel<code>} then the channel will be closed, the thread's interrupt
   * status will be set, and the thread will receive a {@link
   * java.nio.channels.ClosedByInterruptException}.
   *
   * <p> If this thread is blocked in a {@link java.nio.channels.Selector}
   * then the thread's interrupt status will be set and it will return
   * immediately from the selection operation, possibly with a non-zero
   * value, just as if the selector's {@link
   * java.nio.channels.Selector#wakeup wakeup} method were invoked.

如果block在io操作上，那么中断状态将被设置，并且抛出相应异常。
   *
   * <p> If none of the previous conditions hold then this thread's interrupt
   * status will be set. </p>
   *
如果不是以上任何一种情况，那么线程的中断状态将被设置。
   * <p> Interrupting a thread that is not alive need not have any effect.
   *
   * @throws  SecurityException
   *          if the current thread cannot modify this thread
   *
