Question

a. Create a class named CarRental that contains fields that hold a renter’s name, zip code, size of the car rented, daily rental fee, length of rental in days, and total rental fee. The class contains a constructor that requires all the rental data except the daily rate and total fee, which are calculated, based on the size of the car: economy at $29.99 per day, midsize at $38.99 per day, or full size at $43.50 per day. The class also includes a display() method that displays all the rental data.

b. Create a subclass named LuxuryCarRental. This class sets the rental fee at $79.99 per day and prompts the user to respond to the option of including a chauffeur at $200 more per day. Override the parent class display() method to include chauffeur fee information.

c. Write an application named UseCarRental that prompts the user for the data needed for a rental and creates an object of the correct type. Display the total rental fee.

Explanation / Answer

import java.util.Scanner;

public class Main
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("Name of person:");
String name = scan.nextLine();

System.out.println("Zipcode:");
int zip = scan.nextInt();

System.out.println("Size of car:(1=economy,2=mid,3=full,4=luxury)");
int size = scan.nextInt();

System.out.println("Days of rental:");
int days = scan.nextInt();

if(size!=4)
{
CarRental cr = new CarRental(name, zip, size, days);
cr.Display();
}
else
{
System.out.print("Do you want a chauffeur? (y/n) ");
scan.nextLine();
char c = scan.nextLine().charAt(0);
boolean chauf = (c=='y') ? true : false;
System.out.println();

LuxuryCarRental lcr = new LuxuryCarRental(name, zip, days, chauf);
lcr.Display();
}
