Assume that class A extends class B, which extends class C. Also all the three classes implement the method test(). How can a method in class A invoke the test()method defined in class C?

Answer is "It is not possible to invoke test()".

class C {
  
    public static void test(){
        System.out.println("IMESH ISURANGA");
    }
}
  
class B extends C {
  
}

class A extends B {
  //how prove it
}
  
class Demo {
  
    public static void main(String[] args) {
  
        //----
        
    }
}

How to prove it?

    Hint: the exercise you are trying to solve is about non-static methods ... not static methods. – Stephen C Aug 31 '21 at 07:14
  • The key is in "all the three classes implement the method test()" You are missing the methods in class B and C. If you implement these, the function 'test()' in class B will override the one of class C. As A extends B, A can only use 'super.test()' which will call the implementation of class B. as Stephen has indicated: your method should not be static. – Stijn Dejongh Aug 31 '21 at 07:29
