The Object class sits at the top of the class hierarchy
tree in the Java development environment. Every class in
the Java system is a descendent (direct or indirect) of the
Object class. The Object class defines the basic state and
behavior that all objects must have, such as the ability to
compare oneself to another object, to convert to a string,
to wait on a condition variable, to notify other objects
that a condition variable has changed, and to return the
object's class.

listen first , when you create object of one class which is not extending any class than , instead of one object , two object will be created and that is nothing but object of Object class and one more thing is no object is created with out it's superclass. So, object of subclass can not be created without it's superclass where Object class comes into picture because by default compiler gives Object class as superclass to all class which is not extending any class at compilation time itself.
