Threads

Q1: Which class or interface defines the wait()notify(),and notifyAll() methods?

A Thread

B Class

C Runnable

D Object

ANS:A - Object

The Object class defines these thread-specific methods. Option B, C, and D are incorrect because they do not define these methods. And yes, the Java API does define a class called Class, though you do not need to know it for the exam.
