Java multithreaded Learning-synchronous thread communication

This example is on-line Rotten Street, sub-thread loop 100 times, the main thread loop 50 times, but I tried many times, and from the Internet to find a lot of examples, actually run more than a few times, see the output is not correct. I don't know if I turned Niu Jiao Jian, or what happened. Nor did the great God ask, so painful. Now record here, wait for time to see later.
