Question

Instructions

Using the installed software for this course create a generic class called VehicleRental which accepts any generic type of Vehicle ( create an instance of Car, Van and MotorCycle classes)

Each type of Vehicle object has methods called drive, start and stop ( add simple print statement)

The VehicleRental class has a method called rent which accept a generic type of Vehicle object, this method will call drive method of passed Vehicle object

The solution will produce the following:

1. VehicleRental class
2. Vehicle interface from which following classes will implement
3. Car, Van and MotorCycle classes
4. VehicleRentalTest class with main method

Answer 1

Since you have not mentioned the language of your preference, I am providing the code in Java.

CODE

interface Vehicle {

void drive();

void start();

void stop();

}

class Van implements Vehicle {

@Override

public void drive() {

System.out.println("Driving the van...");

}

@Override

public void start() {

System.out.println("Starting the van...");

}

@Override

public void stop() {

System.out.println("Stopping the van...");

}

}

class Car implements Vehicle {

@Override

public void drive() {

System.out.println("Driving the car...");

}

@Override

public void start() {

System.out.println("Starting the car...");

}

@Override

public void stop() {

System.out.println("Stopping the car...");

}

}

class MotorCycle implements Vehicle {

@Override

public void drive() {

System.out.println("Driving the motorcycle...");

}

@Override

public void start() {

System.out.println("Starting the motorcycle...");

}

@Override

public void stop() {

System.out.println("Stopping the motorcycle...");

}

}

class VehicleRental<T extends Vehicle> {

public void rent(Vehicle v) {

v.drive();

}

}

public class Main {

public static void main(String[] args) {

VehicleRental<Car> vr1 = new VehicleRental<>();

vr1.rent(new Car());

VehicleRental<Van> vr2 = new VehicleRental<>();

vr2.rent(new Van());

VehicleRental<MotorCycle> vr3 = new VehicleRental<>();

vr3.rent(new MotorCycle());

}

}
