The class also includes adisplay() method that displays all the rental data. Create a subclassnamed LuxuryCarRental. This class sets the rental fee at $79.99 per dayand prompts the user to respond to the option of including a chauffeur at$200 more per day. Override the parent class display() method to includechauffeur fee information. Write an application named UseCarRental thatprompts the user for the data needed for a rental and creates an object ofthe correct type. Display the total rental fee.

A. Build a class named car. This class is defined as follows: It has the fields: Car ID, Car model, Car make, Car color, Car year. Build a constructor that accepts the five parameters (Car ID, Car model, Car make, Car color, Car year). Override the method toString() to return the string representation of Car ID, Car model, Car make, Car color, Car year. Build a method named display to print the values returned by toString() method. Override the equals() method to compare the Car model, Car make, Car color of two Car objects. The method returns true if all the values of these fields are the same, and false otherwise. In the equals method you must check the following: a. If you compare the Car object to itself, return true.! b. If you compare car object with another car object return true, otherwise return false. Hint use : instanceof operator for this purpose. Override the hashcode() method to return same hash codes for objects that are equal according to the equals() method you built…

Part A Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent. Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field. Also create a get method for each field. Part B Write an application called TestApartments that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available. An example of the program is shown below: Enter minimum number of bedrooms needed >> 2 Enter minimum number of bathrooms needed >> 1.5 Enter maximum rent willing to pay >> 1200 Apartments meeting criteria of at least 2 bedrooms, at least 1.5 baths, and no more than…
