Problem Description
Method Override: Animal Sounds
In this problem, you will create a program that overrides the makeSound() method in Cat and Dog classes that extend a parent Animal class, and outputs the appropriate sound for each animal type read from standard input.
Learning Objective: Understand how to change parent class behavior using method overriding
Overview
Method overriding allows redefining parent class methods in child classes. This enables different behaviors with the same method name.
Specifications
Create parent class Animal:
makeSound()method: outputs "Some sound"
Create child class Cat:
- Extends
Animal - Override
makeSound(): outputs "Meow"
Create child class Dog:
- Extends
Animal - Override
makeSound(): outputs "Woof"
In Main class:
- Read the number of animals
nfrom standard input - Read
nlines, each containing an animal type ("cat","dog", or"animal") - Create an instance of the appropriate class and call
makeSound()for each
Input Format
n
type1
type2
...
- Line 1: number of animals
n(n ≥ 1) - Next
nlines: animal type, one ofcat,dog, oranimal
Output Format
Output each animal's sound on a separate line in input order.
(sound of type1)
(sound of type2)
Sample I/O
Input:
