Method Overriding: Animal Sounds
Easy
Problem Description
Method Overriding: Animal Sounds
In this problem, you will create a program that defines an Animal parent class with a speak() method, then creates Dog and Cat subclasses that each override speak() using the @Override annotation. The program reads animal types from input and displays each animal's sound.
Learning Objective: Redefine parent method in child class with @Override
Create Animal class representing animals and Dog/Cat classes inheriting from it. Override parent's speak() method in child classes to output different sounds.
Input
Line 1: Number of animals N (N ≥ 1)
Next N lines: Animal type ("dog" or "cat")
Output
Print each animal's sound on a separate line.
- dog:
Dog says: Woof! - cat:
Cat says: Meow!
Examples
Example 1: Dog then cat
Input:
2
dog
cat
Output:
Dog says: Woof!
Cat says: Meow!
Example 2: Cat then dog
Input:
2
cat
dog
Output:
Cat says: Meow!
Dog says: Woof!
How Overriding Works
- Define speak() method in parent class Animal
- Redefine speak() with @Override in child class Dog
- Similarly redefine in child class Cat
- When calling speak() on each instance, the respective child class implementation executes.
Test Cases
※ Output examples follow programming industry standards
Normal case
Input:
1 cat
Expected Output:
Cat says: Meow!
Normal case
Input:
3 cat dog cat
Expected Output:
Cat says: Meow! Dog says: Woof! Cat says: Meow!
