Francis · Answer

is there any problem whenever we use abstract class instead of interface class? First of all interface is not a class where abstract class is a partially implemented class. ASFAIK you will go with abstract class in the below scenarios: 1. You are going to build a Parent class. 2. You want to give some concrete methods as well declare some abstract methods. ASFAIK you will go with interface in the below scenarios: 1. You going to declare only Contracts Normally these kind of considerations will be taken during the design phase of an application. Hope this helps!
