How to implement nested interfaces in java programming

An interface which is declared inside a class or another interface is called a nested interface or a member interface. A nested interface can be declared as public, private or protected. Let’s look at an example of how to create and use a nested interface: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 class A { int x; public interface IA { void method(); } } class B implements A.IA { public void method() { System.out.println(“Method implemented successfully”); } } public class Driver { public static void main(String args)
