Create a class named CarRental that contains fields that hold a renter\'s name,

Question

Create a class named CarRental that contains fields that hold a renter's name, zip code, size of the car rented, daily rental rate, length of rental (in days), and total cost. The class contains a constructor that requires all the rental data user information (name, zip, size, length). The daily rental rate depends on the size of the car:

economy: $29.99 per day

midsize: $38.99 per day

fullsize:    $43.50 per day       

Calculate the total cost for the rental car and include a display( ) method to display all the rental information.

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

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 rental information with the total cost for the car.
