Looping multiple threads out of the 0-99-0-99

Directly on the code, after I also have a question, about the object of Notifyall or notify or single or Singleall, wake-up thread is sequential wake up, I here are sequential output

On the issue of fair and unfair lock-up? Is it fair to awaken??? And no big guy to help answer!

Output:
