In Java "Object" class is super for all classes and every
entity we consider as object in java. Every object in java
has default behaviour of "Object" class.
Now come to the point, When you instantiate a thread you
may require to stop a while that particular thread.So
Thread class has sleep method.
But in the situation of multithreading, you may require wait
() and notify() methods so that you can invoke "Object"
class behavior to your class.
