By Encapsulating the implementaion, the client can not see 
actual implementation classes. Cient can see only 
abstraction class, thru which (abstraction class) client 
can create the different objects.
Ex: Shape class is Abstraction class
    Circle class, Square class is encapsulated, but the 
client can create the circle, square shapes by abstraction 
class i.e Shape class.
Hope I have clarified the doubt.
