Question

Write a Java program for a vehicle class (super/parent class) and Taxi class (sub/child class) as per the UML diagram given below. Please use the principles of inheritance while dectring classes.

Answer 1

In Java, the superclass is defined using the 'class' keyword followed by the superclass name and the subclass is defined using the 'extends' keyword followed by the superclass name.

Step-by-step explanation:

In Java, the superclass (or parent class) can be defined using the keyword 'class' followed by the name of the superclass. The subclass (or child class) can then be defined using the 'extends' keyword followed by the superclass name. In this case, the superclass would be the 'Vehicle' class and the subclass would be the 'Taxi' class.

Here is an example of how the superclass and subclass can be declared:

public class Vehicle {
// class implementation
}

public class Taxi extends Vehicle {
// class implementation
}

The 'extends' keyword establishes an inheritance relationship between the superclass and subclass, allowing the subclass to inherit the properties and methods of the superclass.
