Java Polymorphism - Sports Class with Football, Basketball, and Rugby Subclasses for Playing Statements

Java Polymorphism: Exercise-5 with Solution

Write a Java program to create a base class Sports with a method called play(). Create three subclasses: Football, Basketball, and Rugby. Override the play() method in each subclass to play a specific statement for each sport.

In the given exercise, here is a simple diagram illustrating polymorphism implementation:

In the above diagram, the Sports class is the base class with a play() method. The Football, Basketball, and Rugby classes are subclasses that inherit from the Sports class and override the play() method to provide their specific implementation.

Sample Solution:

Java Code:

// Sports.java
// Base class Sports
class Sports {
    public void play() {
        System.out.println("Playing a sport...\n");
    }
}

// Football.java
// Subclass Football
class Football extends Sports {
    @Override
    public void play() {
        System.out.println("Playing football...");
    }
}

// Basketball.java
// Subclass Basketball
class Basketball extends Sports {
    @Override
    public void play() {
        System.out.println("Playing basketball...");
    }
}

// Rugby.java
// Subclass Rugby

class Rugby extends Sports {
    @Override
    public void play() {
        System.out.println("Playing rugby...");
    }
}

// Main.java
// Main class
public class Main {
    public static void main(String[] args) {
        Sports sports = new Sports();
        Football football = new Football();
        Basketball basketball = new Basketball();
        Rugby rugby = new Rugby();

        sports.play();
        football.play();
        basketball.play();
        rugby.play();
    }
}

Sample Output:

Playing a sport...

Playing football...
Playing basketball...
Playing rugby...
