 Q1. What will be the output of following code ?

Base Interface

public interface BaseInterface {
   int i = 4;

Derived Interfaces

public interface DerivedInterface1 extends BaseInterface{
   int i = 5;

public interface DerivedInterface2 extends BaseInterface{
   int i=6;

Implementing Class

public class Class implements DerivedInterface1,DerivedInterface2 {
   public static void main(String[] args){

What will be the output upon executing main and Why ?
Core Java
Ans. It will print 4 because member elements of an interface are implicitly static and hence the concept of overriding doesn't work.
