abstract class: inheritance Hierarchy

In this problem, you will create a program that implements a multi-level abstract class hierarchy (Vehicle → LandVehicle → Car), progressively implementing abstract methods at each level, and displays the result to standard output.

Learning Objective: Understand multi-level inheritance hierarchy using abstract classes

Overview

Inherit a LandVehicle abstract class from a Vehicle abstract class, then implement a concrete Car class. Implement multiple abstract methods progressively.

Specifications

• Vehicle class (abstract):
  • Define abstract method move()
  • Define abstract method getType()
• LandVehicle class (abstract, inherits Vehicle):
  • Implement getType() to return "Land"
  • move() remains unimplemented (stays abstract)
• Car class (inherits LandVehicle):
  • Implement move() to output "Driving on road"
• In Main class, create Car object and call getType() and move()

Output Format

Land
Driving on road
