super Call in method Chain

In this problem, you will create a program that uses the super keyword across a 3-level class hierarchy (Grandparent→Parent→Child) to chain parent method calls and displays each level's message to standard output in sequence.

Learning Objective: Understand method chaining with super in inheritance hierarchy

Overview

Create a program with 3-level class inheritance where each level calls methods via super, stacking processing.

Specifications

• Grandparent class has greet() method (outputs "Hello from Grandparent")
• Parent class extends Grandparent and overrides greet() (calls super.greet() then outputs "Hello from Parent")
• Child class extends Parent and overrides greet() (calls super.greet() then outputs "Hello from Child")
• Call greet() on child instance in Main

Output Format

Hello from Grandparent
Hello from Parent
Hello from Child
