Re: Is there any benefit to extend both Interface and abstract class hi hani good question. if class C extends Class B(which is implementing intrface A according to it's requirement) then class C gets all the features of class B and again if class C implements interface A then C can implement it own features.. so now C will get both the class B features and it's own features.. now i think u got something thanks..
