JAVA I Final Project – Hotel Reservation System For your final project, you will be creating a program that interacts with the user to add and review hotel reservations. Design For this project, you will need to design and implement the following classes (at a minimum): Reservation Class: The class should store the first name, last name, number of night and daily rate for a hotel reservation. The class should provide the following methods: print : Returns a String that contains the information in the reservation getTotalCost : This method multiplies the daily rate by the # of nights and returns the total price ReservationSystem Class: The class should store an array of Reservation s. The next available reservation ID ( nextID ) The class should provide the following methods: addReservation : Takes as input last name, first name, ID, # of nights, and daily rate and creates a Reservation with this information. Add the reservation to the array of reservations. If the ID of the reservation is larger than the next available reservation ID ( nextID ), it updates nextID to be 1 more than the ID it just read in. addReservation : Prompts the user for the info needed to make a new reservation. Add the reservation to the array of reservations. Assign the next ID findReservation : find a reservation by ID and return it findReservation : find a reservation by first and last name and return 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 array. Uses the addReservation method for help. downloadReservations: asks the user for a file and writes the reservations to the file. Use the print method provided by Reservation updateReservation : asks the user for the ID of the reservation to update and then asks for the data to be updated and updates the reservation getTotalCost : Calls getTotalCost on each individual Reservation and adds them all up Documentation: All methods implemented should have javadoc comments written for them. Program Input: Your program will display a welcome message to the user and a menu of options for the user to choose from. After completing a task, the main menu will be displayed again. Program Options Option 1: Upload Reservations If the user chooses this option, the program will Prompt the user for the file that contains the reservations. Read in the records into the ReservationSystem . Note: You can assume that the file will NOT contain more than 100 records. Input File Format: ReservationID LastName FirstName Nights DailyRate Sample Input File: 1 Bob Mike 2 140.23 2 Matt Benjamin 4 90.00 3 Keller Helen 1 98.10 4 Tim Mary 3 23.10 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 the ReservationSystem . The method will assign a unique id to the reservation using the nextID stored in ReservationSystem. Option 3: Update Reservation When this option is selected, the program will ask for the ID of the reservation and prompt the user for the new name, # of nights and daily rate. 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: ID: 1, Name: Mike Bob, Nights: 2, Daily Rate: 140.23 ID: 2, Name: Benjamin Matt, Nights: 4, Daily Rate: 90.00 ID: 3, Name: Helen Keller, Nights: 1, Daily Rate: 98.10 ID: 4, Name: Mary Tim, Nights: 3, Daily Rate: 23.10 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) Longest stay Total cost of reservations – use the getTotalCost method in the ReservationSystem class The statistics file will have the same name as the input file (from option 1) but with _stats.txt appended to it. For example, if the input file was named reservations.txt , the stats file will be named reservations_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. What to Hand in: a zip file containing your javadocs, your java files as well as the statistics file and a screen shot of running your program using the following sequence of steps: Option 1 to add customers from reservations.txt provided with this project Option 4 to view reservations Option 2 to add a new reservation Option 2 to add a new reservation Option 4 to view reservations – confirm the 2 reservations you added are there Option 3 to update a reservation Option 4 to view reservations – confirm the update happened correctly Option 5 to find a reservation that exists Option 5 to find a reservation that does not exist Option 6 to download the statistics file Option 7 to exit Reservations.txt 1 Bob Mike 3 140.23 2 Matt Benjamin 4 90 3 Keller Helen 8 98.15 4 Tim Mary 4 23.1 5 James Alan 3 47.77 6 William Carla 6 94.92 7 Mathew Robin 7 53.7 8 Jacob Tom 6 79.98 9 Nathan Norman 9 230.1 10 Nick Nate 8 537 11 Ethan Mary 6 87.9 12 Kate Helen 2 20.8 13 Benjamin Alan 4 90.44 14 John Jamie 2 89.88 15 Bob Annie 3 100
