Create a test class to test the methods available in all these child class.

Answer 1

The student's question involves creating an abstract class Vehicle within the com.automobile package and defining two subclasses Hero and Honda with specific methods, including a test class to validate their functionality.

Step-by-step explanation:

Abstract Vehicle Class and Subclasses in Java

To address the student's request, one needs to create an abstract class Vehicle inside the package com.automobile. This class must contain three abstract methods: getModelName(), getRegistrationNumber(), and getOwnerName. Subsequently, two subclasses are defined within a twowheeler subpackage: Hero and Honda. The Hero class extends Vehicle, implementing methods to get the speed of the vehicle and control the radio. The Honda class also extends Vehicle, with methods to get the vehicle's speed and to control a CD player. Lastly, a test class is necessary to confirm the functionality of methods in both Hero and Honda classes.
