I have trouble understanding this.
the args objects that we are locking are completely different instances. Why would the notify method of AnotherThreads arg object matter to main method's arg parameter?

[admin]

Why do you think that args objects are completely different instances. It is the same args array object that is being passed by the main method to AnotherThread.
