I am studying OCP Java SE7 Programmer II exam. OCA/OCP Java SE7 Programmer I&II Study Guide  by Kathy Sierra and Bert Bates. I am in Chapter 13 Threads now. I came across with the codes from the book, which doesn't seem to be working. I could not figure out why. The following are the codes.



And the output is>>>



As you see the code doesn't reach to "The wait is over". Apparently notifyAll() does not really notify the thread in the Reader class. What am I missing? Thank you for your time in advance.

I figured that out. The waiting thread has to start before the notifing thread. That is.
