Description The program in this assignment is a flight booking system that can be used by any company to book flights for its customers. The sales staff in a company will use the system to: (1) Add flight details in the system, (2) Add passenger details in the system, (3) Make a new reservation for a customer based on the request. To use the flight booking system, sale staff has to set initial parameters one time. These parameters are the total number of flights the system has to manage, the total number of passengers the system has to create records for, and the number of booking requests the system has to make [see sample output file]. The Initial Procedure of the Program To set the initial parameters, your program will first read the following parameters from [input.txt]: 1. Total Number of Flight 2. Total Number of Passengers 3. Number of Booking Requests These parameters will be in the first line of the file [input.txt]. To read from the file, the system should first check if the file [input.txt] exist or not and will display an error message if the file does not exist. The first number (3) in the first line determines the Total Number of Flights [this means the system will have the maximum of THREE Flights] The second number (10) in the first line determines the Number of Passengers [this means the system will have the maximum of TEN Passengers] The third number (2) in the first line determines the Number of Booking Requests [this means the system will create a maximum of TWO Reservations] The system (your program) then will read the following command to perform one of the programs methods: Add_Flight Using this command, the system will add the flight details based on the total number of flights available in the system [ see sample output file]. Example In this line Add_Flight is the command and SA220 Jeddah Makkah 416 8 450 are the details of the flight where SA220 is the flight code, Jeddah is cityFrom, Makkah is cityTo, 416 is the total number of seats, 8 the remaining number of seats, and 450 is the price [see Figure1]. Note that the system will not allowed more than Total Number of Flights to be registered. If this happen, a message that says Flight Flight_code Was not Added, You exceed the maximum number of Flights" will be displayed. Add_Passenger Using this command, the system will add the passenger details taking into account the total number of passengers allowed in the system [ see sample output file]. Example In this line Add_Passenger is the command and Saud_Ahmad 25 M 053547099 are the details of the passenger where Saud_Ahmad is the name, 25 is the age, M is the gender, and 053547099 is the phone number. Note that the system will not allowed more than Total Number of Passenger to be registered. If this happen, a message that says Passenger Passenger_name Was not Added, You exceed the maximum number of Passengers" will be displayed. Make_Booking Through this command, the system will create a new reservation for a customer based on the number of booking requests allowed in the system [ see sample output file]. Example [ Make_Booking flight_code number_of_passengers passenger1_name passenger2_name .] In the above command the system will book a flight for 2 passengers in the flight SA220. Notes that when the system makes a new booking: The system will first check the flight code that the customer wants to book. If the flight code is not in the system, the system should display an error message that says, the flight code is not in the system. The system will check the passengers name who want to travel in current booking [ see sample output file]. If one of the names is not in the system, the system will display an error message that says, passenger_name is not a registered passenger. If the seats requested exceed the number of available seats in this flight, the system will display an error message that says, seats requested exceed the number of available seats. 4. The system will not allow more than Number of Booking Requests to be registered. If this happen, an error message that says, you exceeded the number of booking requests will be displayed. Finally, the method will generate and return a unique passenger name record (PNR) for every booking, PNR must start from JED100 onwards, i.e., First booking JED100, next booking JED101, Next JED102, etc. [remember PNR is not fixed value] Search_Print This command will search and print a booking information given a PNR code [ see sample output file]. This option will show complete details of the booking, which includes the flight details, the passenger details, and the flight cost [ see sample output file]. Note that this command will return an error massage if the PNR is not found. For example, PNR JED103 is not a valid PNR code Example This command will show complete details of the booking JED100 Flight_Status This command will print / display complete flight status and details which includes available seats, destinations (from/ to), etc. Note that this command will return an error massage if the flight number is not found. For example, Flight number SA710 is not found in the system [ see sample output file]. Example This command will display the complete information of the flight SV768. Class Description: You have to create the following base classes in this program. Flight class Passenger class Reservation class 1. The Data fields in the Flight class are as follows. flightCode SV768 cityFrom Jeddah cityTo Dammam totalSeats 5 remmaningSeats 1 price 450.0 2. The Data fields in the Passenger class are as follows. Name Ahmed Zahrani age 24 gender M Phone 05354703383 3. The Data fields in the Reservation class are as follows. PNRNumber JED100 ReservationDate 2015-02-26 Flight Object from flight Passenger [] Array of Passengers as there might be more than one passengers travelling in same booking. You program also need to include a class called FlightReservation.java class to test the Booking System. This is your main class in the application. See the UML diagram to know complete data members and methods required in each class. The UML Diagram Figure 1: UML Diagram Flight Booking System You will have to create the following arrays: Flight [] flight, which is an array of Flight objects. Passenger [] passenger, which is an array of Passenger objects. Reservation [] reservation, which is an array of Reservation objects. Methods and their description: a) inputFlight This method will be used to read the flight details from the input file and add the flight details to the system. System only allows limited flight entry [see sample output file]. b) inputPassenger This method will be used to read the passenger details from the file and enter passenger details to the system. System only allows limited passenger entry [see sample output file]. c) BookingFlight This method will make booking based on the details from the file. System only allows limited booking entry [see sample output file]. d) FlightStatus This method will search and print the details of a flight given its flight code. The method will also list all the passengers in these flights [see sample output file]. e) Bookingdetails This method will search and display the details of a single booking given its PNR code. The functionality of the classes is shown in UML diagram, see Figure 1, mainly there are mutators(setter) and accessors (getter) in every class see Figure 1. Important Notes: Your Code, output, results etc. must be in a readable form. Organize your code in separate methods. Repeat the program until Quit command is read by your program. Use comments in your code. Use meaningful variables. Use dash lines separator between each method. Output Format Your program must generate output in a similar format to the given sample output file. Good Luck and Start Early!
