Question

You will write a program to run a car rental shop.

The program will work as follows:

On startup, it will read a file of Cars, staff, and customers (storing each into a single array, so you should have 3 arrays when you read everything).

It will then display a menu of choices, allowing staff to repeatedly select the choices.

When the staff chooses to quit the program, it will first write out the arrays back to the files it read it from. Meaning cars will be written out to cars.txt and customers will be written back to custoerms.txt.

Simplifying assumptions:

We will assume a maximum of 100 cars, customers. We will not allow for the possibility of needing to increase the size of the array. You may assume that no one will ever try to put more than 100 cars or customers in the array.

You will create getters and setters methods that you need. If you create a method that you don’t use, you will lose points.

The following need to be verified before it gets stored in the array:

Phone number need to be 10 digits long

Date need to match the format MM/DD/YYYY

Credit card number need to be 16 digits long

You can’t rent unless the customer has Insurance. Meaning if you hit enter it should not let you through to the next step of reservation.

Program classes:

Car, customers, staff classes. See details below.

Insurance – which will only manage the insurance info includes company and expiration date.

Reservation class – manages the car reservations. See details below.

Driver class – manages the program. See details below.

UserCredential and verify class- which will manage the staff login to the console.

DataManager- read the customer and car info into arrays and writes info the files again at exit.

Program Files:

We will provide you with 3 text files. Staff.txt, car.txt, and customer.txt

Car class:

General description:

The Car class manages information about a car.

Instance variables:

Make

Model

VIN

Year

Category: such as Economy, Luxury, Full-size car, Full-size Van, and convertible.

Constant for the prices for each category

Economy rate is $30

Luxury rate is $40

Full-size car rate is $35

Full-size Van rate is $50

Convertible rate is $50.

Mileage on the car at the time of rental or return.

Customer – an instance of the customers class for the customer who is renting a car.

Reservation flag. Set to true if the car is reserved. And false if its not.

oilChange mileage- stores the mileage for the last time the car had its oil changed.

Methods:

A constructor that takes make, model, VIN, year, mileage, oilChange, reservation flag, category.

Second constructor that takes make, model, VIN, year, mileage, oilChange, reservation flag, category, and customer.

updateMiles()- takes the returns miles for the car and add it to the mileage of the car. Meaning is if the customer rented a car with 30000miles and drove it for 3000 miles then the method will update the 30000 to 33000 miles.

oilChange()- this method will decide if a given car will need to have its oil changed. The way this works is, if car drove 3000 miles since the last time the oil was changed then you need to flag it to have it serviced again. And you need to flag a car whose mileage is close to be services ( let’s say 300 miles). Meaning, if a car was services at 3000 miles and someone drove it for more than 3000 then this car need to be flagged to be services. Or if a car is 300 miles shy of being services then you need to flag it to have its oil changed. When listing them, the system will ask the admin if someone changed the oil of the car, if yes then the oilChange will be set to the current car mileage if no then nothing is changed.

Getters and setter’s method that you need. Only create what you need.

toString()- format the output of the car in a table like. Please see the sample output for it. in this method you need to see if a car has reservation then you need to have the customer information added the string you are returning. But if the car don’t have any reservation, then just output the car info. For example

addCustomer()- takes a customer object and add it to the customer array.

searchCustomer()- takes a phone number for the customer the staff is trying to find. Look through the whole array for customer with that phone number, if it exist you return the customer info.

writeCustomer()- method that write the customer array to customer.txt file in the same format as it initially started.

3-Luxury car        $40      

4-Convertible car   $50      

5-Full-size Van     $50

readCustomerInfo()-don’t pass anything to this method. This method first will look to see if the customer who is trying to rent a car is in the system or not. You do customer search by phone number. if the customer exists then you print out the customer info and currently don’t have a reserved car then you proceed with reservation. But if the customer have reservation already, then the program exit and tells you to return the current car first then allow for a new reservation. If the customer does not exist, then you need to take his info and store it in the customers array.

Reserve()- this method will need the customer info for the reservation as well as the inventory of the cars. Don’t pass anything to the method. According to the staff choice of car to rent (see chooseCar()), you need to set the rate and the category. If there is no cars left in that category then list all the cars available to rent and let the user choose which car to rent with the same rate as the first initial category. Meaning is if there is no more Economy cars to rent then let the customer choose from any of the cars you have in the inventory with the same rate as the economy one. You will reserve a car according to the VIN number. part of reservation is to set the customer flag for reservation to true as well as the flag for reservation for the car. In addition, set the start mileage to the current car mileage as well as the number of days to reserve the car. Use the writeCustomer and writeCar methods at the end to update the text files.

carReturn()- this method takes the VIN number. search for the car with that VIN number and set the reservation flag to false as well as the reservation flag for the customer to false. The method will record the mileage that was driven and update the mileage on the car. Use the writeCustomer and writeCar methods at the end to update the text files.

Summary method that prints a summary for the car reservation,

Summary_return that prints a summary for the car return.

Driver class:

First you need to ask the staff to login in, ask for the username and password.

If the staff exist in the system, show a welcome message. Otherwise keep asking for a username and password. The staff can try to login 3 times. more than 3 attempt the program will exist.

1- reserve a car

2- a car return
