Please explain O/P ...

interface A {int i = 1; int m1();}
interface B extends A {int i = 10; int m1();}
class C implements B {
  public int m1() {return i;}
  public static void main(String[] args) {
    System.out.print(new C().m1());
}}
 

Above code returns value 10 upon excution. My doubt is why doesn't it throws a compile time error complaining about ambiguoity as interface B inherits 'i' from interface A as well and since class C implements B, how will method m1 ascertain which 'i' to return ?

A.i is hidden by B.i, as static members are hidden and not Overridden.
Try with

A a = new C();
System.out.println(a.i);

This prints 1 as there is no polymorphism for variables(instance or static).
