basically in java we have 2 types of classes. those are user
defined classes and pre defined classes. in both we can
differentiate the classes in 3 ways. those are interfaces,
abstract classes and concrete classes. Where we can't create
the objects for the abstract class and interfaces. by using
inheritance concept we can able to create the object of the
for the derived classes and assign those objects to the base
class references(according to OOP concept).
Thank you.
