Java Inheritance Programming - Animal Class with a method move()

Last update on May 16 2025 13:07:31 (UTC/GMT +8 hours)

Write a Java program to create a class called Animal with a method named move(). Create a subclass called Cheetah that overrides the move() method to run.

Sample Solution:

Java Code:

// Animal.java
// Parent class Animal

// Define the Animal class
public class Animal {
    // Method to print a message indicating the animal moves
    public void move() {
        System.out.println("Animal moves");
    }
}

// Cheetah.java
// Child class Cheetah

// Define the Cheetah class, inheriting from Animal
public class Cheetah extends Animal {
    // Override the move method to print a cheetah-specific message
    @Override
    public void move() {
        System.out.println("This cheetah is running!");
    }
}

// Main.java
// Main class

// Define the Main class
public class Main {
    // Main method to run the program
    public static void main(String[] args) {
        // Create an instance of Animal
        Animal animal = new Animal();
        // Call the move method on the Animal instance
        animal.move();
        
        // Create an instance of Cheetah
        Cheetah cheetah = new Cheetah();
        // Call the move method on the Cheetah instance
        cheetah.move();
    }
}

Output:

Animal moves
This cheetah is running!

Explanation:

In the above exercise, the Animal class has a single method called move(). This method simply prints a message to the console saying the animal is moving. The Cheetah class extends the Animal class and overrides the move() method to print a message that Cheetah is running.

In the Main class, we create an instance of the "Animal" class and call its move() method. This prints the "This animal is moving" message to the console. We also create an instance of the "Cheetah" class and call its move() method. This prints the "This cheetah is running" message to the console.
