HI , I have some doubt regarding on Multithreading in java.why wait() , notify() and notifyAll() methods are in Object class not in Thread class.Can anybody please try to explain me why this type of implementations have done?
Because thread synchronization is all about protected resources. Your thread always waits on[/] some object. (And it's always the current thread, so the thread doesn't have to be supplied to the call.)

These methods deal with locks, not threads, and any object can serve as a lock. If you were to ever use them for real, you'd see that they HAVE to be on Object.
