polymorphism with ArrayList

In this problem, you will create a program that defines Dog, Cat, and Bird subclasses extending Animal, overrides the speak() method in each subclass, stores instances in an ArrayList<Animal>, and displays each animal's sound to standard output by calling speak() in a loop.

Learning Objective: Understand how to store different child class objects in parent class type ArrayList

Overview

Create a program that stores different child class instances in parent class type ArrayList and utilizes polymorphism.

Specifications

• Define Animal class and its subclasses (Dog, Cat, Bird)
• override speak() method in each class
• Add various animals to ArrayList and output sounds in loop

Output Format

Woof!
