Sujeet Suman · Answer

Anjali we should use ABSTRACT class in below scenarios: (01.) When we need to implement abstract methods (only signature) as well as nonabstract methods (full method). (02.) When we need to keep ( common implementation + different implementation ) (03.) Abstract classes allow us to provide default functionality for the subclasses. So when we need to provide default functionality for all sub classes then we should use abstract class. If this is helpful for you then please accept my Answer .
