Question: What is the difference between Abstract class and Interface
Answer:
Answered by Scott on 2005-05-12 10:03:06: An abstract class can contain non-abstract methods which do not have to be overridden in the subclass.
There is no difference between a fully abstract class (all methods declared as abstract and all fields are public static final) and an interface. |

Abtraction and Encapsulation
|
The main differece is
Abstraction: In this we can identify the specific properties and attributes of a pertricular class.
and exposing the data to the user ..........
example: A car, we can know or see that what it look lies in color , in the restpect to body of car but we can not know the fearchers they are using into the car
Encapsulation:
Binding the data and functions into the single unit.
i.e in the other way u can say that hiding the details from the others..
example :
same Car
in which we can see how the car is but when it is not working in that case i can not repaire it b'coz all the details of repairing are hidden from me ... |
