Design

For this project, will need to design and implement the following classes (at a minimum):

Reservation Class:

The class should store the first name, last name, flight price, seat number and seat letter. The class should provide the following methods, at a minimum:

print: Returns a String that contains the information in the reservation

getPrice: Returns the price of the reservation

ReservationSystem Class: The class should store an ArrayList of Reservations.

The class should provide the following methods:

addReservation: Takes as input last name, first name, price, seat number and seat letter and

creates a Reservation with this information. Add the reservation to the list of reservations.

addReservation: Prompts the user for the info needed to make a new reservation. Add the

reservation to the list of reservations.

findReservation: find a reservation by first and last name and returns it

viewReservations: prints all reservations using System.out. Use the print method provided by Reservation

uploadReservations: asks the user for a file and reads in all the reservations from a file and saves them in the ArrayList. Uses the addReservation method for help.

downloadReservations: takes a file as input and writes the reservations to the file. Use theprint method provided by Reservation

updateReservation: asks the user for the first and last name of the reservation to update and then asks for the data to be updated and updates the reservation.

getTotalPrice: Calls getPrice on each individual Reservation and adds them all up

Documentation:

All methods implemented should have javadoc comments written for them.

Program Options

Option 1: Upload Reservations

If the user chooses this option, the program will a. Prompt the user for the file that contains the reservations. b. ReadintherecordsintotheReservationSystem.

Input File Format: LastName FirstName Price SeatNumber SeatLetter Sample Input File:

Bob Mike 200 23 B Matt Benjamin 178 15 A Keller Helen 135.99 6 D Tim Mary 210.77 12 B

Use the uploadReservations method to upload the reservations to the ReservationSystem.

Option 2: New Reservation

This option will prompt the user for the information needed to make 1 reservation and store it in theReservationSystem.

You need to make sure that the seat number is between 1-30. You need to make sure the seat letter is either A, B, C, D or E.

Option 3: Update Reservation

When this option is selected, the program will ask for the first and last name of the reservation and prompt the user for the seat number and seat letter. Use the updateReservation method for this task.

Option 4: View All Existing Reservations

If the user chooses this option, the program will print to the screen all the reservations information. Use the viewReservations method for this task.

Sample Output:

Name: Mike Bob, Price: 200, Seat: 23B Name: Benjamin Matt, Price: 178, Seat: 15A Name: Helen Keller, Price: 135.99, Seat: 6D Name: Mary Tim, Price: 210.77, Seat: 12B

Option 5: Find Reservation

If the user chooses this option, the program will prompt the user for their first and last name and search for a reservation with that first and last name combination and display it to the screen. If no reservation is found, a message will be displayed indicating that. Use the findReservation method for this task.

Option 6: Download Statistics

If the user chooses this option, the program will create a statistics file with the following data:

Printout of all reservations use the downloadReservations method for this task

Sorted customer names alphabetically (by last name)

Lowest flight price

Highestflightprice

Total cost of reservations use the getTotalPrice method in the ReservationSystemclass

4. The statistics file will have the same name as the input file (from option 1) but with _stats.txtappended to it.

For example, if the input file was named reservations.txt, the stats file will be namedreservations_stats.txt.

Note: It will remove the .txt from reservations.txt, before adding the _stats.txt. It will NOT create a file with the name reservations.txt_stats.txt. You can use the string substr method to remove the last 4 characters from the file name.

Write a static function called CreateStatsFile to do this task. Choose the appropriate parameters and return type.

Option 5: Exit the Program

If the user chooses this option, the program will exit. Note: If any other option (other than exit) is chosen, the task will be performed and then the menu will be displayed again.
