Every method present inside interface is abstract but in abstract class also we can take only abstract methods then what is the need of interface concept?

    @Kayaman IMHO this question is not a duplicate. I think the OP wonders why do we need the concept of interface if we can create an abstract class having all its methods abstract. You can find everything in the duplicate but you have to look carefully and it is not obvious as a beginner. Commented Apr 12, 2018 at 9:57

    Should be said in those linked question but the short answer, you can implement more than one interface but only extends one abstract class. Commented Apr 12, 2018 at 12:13
