Determining which method shows polymorphism

[friendbobbiny]

Homework Statement

Which of them is an example of polymorphism?

public Class D extends B
{

public void f()
{
    this.g(); // 1
}

public void g()
{
    super.g(); // 2
}}

Homework Equations

Polymorphism: The ability of an object to refer to objects of other types. The ability of a method to have different functionalities, depending on the class type invoking it.

The Attempt at a Solution

This was what I understood to be my teacher's logic:

Imagine a class E that extends B
The class also rewrites method g().

public static void main(String[]args)
{

E e = new E ();
D d = new D ();

e.f(); // calls the overriden g() method in E
d.f(); // cals the g() method in D, which calls the g() method in B}

I can understand why method f() shows polymorphism via this example. How is method g() not an
instance of polymorphism though?

I think wiki has a better definition:
