Multi-level inheritance Implementation

In this problem, you will create a program that implements a 3-level inheritance hierarchy (Animal → Mammal → Dog), calls methods from each class in order, and displays the result to standard output.

Learning Objective: Understand and implement inheritance relationships across multiple levels

Overview

Implement a 3-level inheritance hierarchy (Animal -> Mammal -> Dog) and call methods from each level.

Specifications

• Animal class: eat() method (outputs "Eating...")
• Mammal class extends Animal: breathe() method (outputs "Breathing...")
• Dog class extends Mammal: bark() method (outputs "Barking!")
• Create Dog instance in Main class and call all three methods

Output Format

Eating...
Breathing...
Barking!
