You are implementing an interface so you must write 'implements A.It1'. If you have an abstract method inside a class than your class must also be abstract. public class Test implements A.It1 { public void m1() {System.out.println("m1"); } public void m2() {System.out.println("m2"); } public static void main(String args[]) { Test t= new Test(); t.m1(); t.m2(); } } abstract class A { abstract void m1(); interface It1 { void m2(); } }

I have covered all 3 in this small example and hope you differentiate all of them. https://code.sololearn.com/cQuGt7nm22GQ/?ref=app

Avinesh -- tqq for ur reply .. it's easy to understand (differentiate) ...In case if the interface A ,classC, abstract class E have their own methods how to implement them whether to use the keyword -> (implement or extend)
