Abstract Class with Default Implementation

This program demonstrates abstract class with default implementation.

Problem Statement

Write a Java program to define abstract class Vehicle with default method fuelType().

Source Code

1	abstract class Vehicle {
2	abstract void move();
3	void fuelType(){ System.out.println("Generic fuel"); }
4	}
5	class Car extends Vehicle {
6	void move(){ System.out.println("Car moves on road"); }
7	}
8	public class AbstractDefaultImplementation {
9	public static void main(String[] args) {
10	System.out.println("Eduinq Abstract Default Implementation");
11	Vehicle v=new Car();
12	v.move(); v.fuelType();
13	}
14	}

Program Output

Eduinq Abstract Default Implementation
Car moves on road
Generic fuel

Explanation

Abstract class can provide default methods. - Subclass inherits default implementation unless overridden. - This balances abstraction with reusable code. Conclusion: Shows abstract class with default implementation.
