We Have two Classes A and B
a is a method in A
b is a method in B
When we inherit Class A into B
After that we create a object referance to Class B
Then what happend in heap area.
Whether two objects are created or only object is created for B

Getting someone to think and try something out is much more useful than just telling them the answer.

Only one object is created and it is of type B, but that object contains all the members of class B, and also the members that it inherited from class A.

Not all members will be inherited ;-).
Only public and protected members will be inherited.if the subclass belongs to the same package as that of super class, then default members in the super class will also be inherited.
