RE: Usage of Abstract class and Interfaces

Depends on the design consideration. If one wants the design to be flexible then go for the interface else abstract class.
The abstract class can contain default implementation which is inherited by the subclasses by default. If you are looking for performance then abstract class is the best choice |
