=================================
For this exercise, you will receive three (3) submissions.
Currently you are not be able to submit, as the exercise is not fully set up.
Once CourseMarker knows how to mark the question, this message will be removed.
Also, note that the test data with which you have been provided is *not* the
test data which will be used. The more observant among you may notice that this
is the test data for Travel4 -- the actual test data has not yet been written.
Introduction
============
This coursework requires you to write an object-oriented program to represent
a fairly simplistic flight booking system.
Each flight is made up of a number of rows of seats in Club Class, and a number
of rows of seats in Economy Class.
A row in Club Class consists of 4 seats. The first and last seats on each row
are window seats. Every seat in Club Class is an aisle seat; thus some are both.
A row in Economy Class consists of 6 seats. The first and last seats on each row
are window seats. The middle two seats are aisle seats. The remaining two seats
are neither window nor aisle seats.
The following shows this in pictorial format:
(W = window, A = aisle, B = both, N = neither)
Club: B A A B
Economy: WNA ANW
The number of rows in each seating class is to be specified by the user.
When the program is run, the user should be presented with the following menu:
Flight Booking Menu
===================
1) Create Flight
Q) Quit
Enter your choice:
If the user enters 'q' or 'Q', the program should print "Quitting...." and then
exit.
If the user enters '1', the Flight Creator menu should be shown, and the user
should be prompted for the destination and departure time. (See the sample
output below for full details of the expected output.)
The user should then be prompted for the number of rows in each seating class
(again, see the sample output). You should then return to the main menu.
Once at least one flight has been added, the menu should look like
Flight Booking Menu
===================
1) Create Flight
2) Make Booking on Flight
3) Print A Flight's Manifest
Q) Quit
Enter your choice:
If the user enters '2' or '3', a list of all available flights should be printed
to the screen. The user should then be prompted to select one of these flights
by its flight number -- this should simply be the order in which the flights
were created, starting with zero.
If the user entered '3', then once they have selected a flight, you should print
the flight's manifest in the following format:
Flight Manifest
Destination: Destination Name Here
Departure time: Departure Time Here
Club Class passenger list:
Row: 0, Column: 2, Name: Passenger1, Nationality: Nationality1
Row: 1, Column: 3, Name: Passenger2, Nationality: Nationality2
Economy Class passenger list:
Row: 0, Column: 0, Name: PassengerX, Nationality: NationalityY
Row: 0, Column: 3, Name: SomePassengerName, Nationality: SomeNationality
If there are no passengers in a seating class, print the message
No passengers in Club Class
or
No passengers in Economy Class
as appropriate, instead of the passenger list.
If the user entered '2', once they have selected a flight, they should be
prompted for a seating class. (See sample output.) If all seats in one of the
classes are full, do not print the corresponding menu option.
Once they have selected a seat type, they should be presented with the Seat
Selection menu:
Seat Selection
==============
1) Pick Specific Seat
2) Any Window Seat
3) Any Aisle Seat
4) Any Seat
Enter Preference:
If the user enters '1', a seating plan should be printed to the screen (see
sample output and further description below) and the user prompted for a row
and column number.
If the user enters '2', the first available window seat should be automatically
selected.
If the user enters '3', the first available aisle seat should be automatically
selected.
If the user enters anything else, the first available seat of any type should
be selected.
For all of the above options, the user should then be prompted for the Person's
name and nationality, and then asked if they wish to book another seat on the
flight. If they enter 'y' or 'Y', they should be prompted with the Seat Type
menu again (see sample output). If they enter anything else, return to the main
menu.
You are provided with the following files:
==========================================
FlightBookingSystem.java
Contains the main method, and should contain the majority (if not all) of
the code for the various menus.
It must also store a list of Flights; we suggest you use an array of Flight
Objects.
Constructor:
You should declare one constructor for the FlightBookingSystem class. It
should take one integer as an argument, used as the maximum number of
storable flights. Hint: use this to set the size of the array of Flight
Objects.
Required methods:
main
This is provided for you. You should not alter it. It creates a new
FlightBookingSystem object with space for 10 flights, and then calls
the runMainMenu method on it.
runMainMenu
This method should be declared public, and should take no parameters
and return nothing. This should contain the main logic behind the
menu system, though you may use helper methods internally as
appropriate. Any helper methods you create must be declared private.
Flight.java
Represents a flight. It must store a destination and a departure time, and
a list of seats.
Constructor:
The Flight class should have one constructor. It should take two ints and
two Strings, representing the number of rows in Club Class, the number of
rows in Economy Class, the destination, and the departure time. (You may
read and store the departure time as a String, and accept any value.)
Required methods:
getDestination
Takes no arguments, and returns a String, the destination.
getTime
Takes no arguments, and returns a String, the departure time.
numRows
Takes a boolean (true for Club Class, false for Economy Class) and
returns an int, representing the number of rows in that class.
numCols
Takes a boolean (true for Club Class, false for Economy Class) and
returns an int, representing the number of columns in that class.
addSeatBooking
Takes a Location Object and a Person Object as arguments, and
returns nothing. Sets the Seat at the specified Location to hold the
specified Person Object.
isSeatEmpty
Takes a Location Object, and returns a boolean. Returns true if the
seat at the specified Location has no Person assigned.
getNextAvailableAisleSeat
Takes a boolean (true for Club Class, false for Economy Class) and
returns a Location Object, representing the next available aisle
seat in the specified seating class. If there are no window seats
available, the method should return null instead of a Location
Object. The 'next available seat' is defined as the topmost,
leftmost seat which has no Person assigned to it and fulfils the
requirement of being an aisle seat.
getNextAvailableWindowSeat
Identical to getNextAvailableAisleSeat, except that it should return
the first available window seat.
getNextAvailableSeat
Identical to the above, except that it should return the first
available seat of any type.
printManifest
Takes no arguments and returns nothing. When called, this method
should print out the flight's manifest in the following format:
Flight Manifest
Destination: Destination Name Here
Departure time: Departure Time Here
Club Class passenger list:
Row: 0, Column: 2, Name: Passenger1, Nationality: Nationality1
Row: 1, Column: 3, Name: Passenger2, Nationality: Nationality2
Economy Class passenger list:
Row: 0, Column: 0, Name: PassengerX, Nationality: NationalityY
Row: 0, Column: 3, Name: SomePassengerName, Nationality: SomeNationality
If there are no passengers in a seating class, print the message
No passengers in Club Class
or
No passengers in Economy Class
as appropriate, instead of the passenger list.
printSeatingPlan
Takes one argument, a boolean, and returns nothing. The boolean
is used to determine whether to print the seating plan of Club Class
or Economy Class.
For Club Class with 2 rows, this should be printed in the following
format:
0 1 2 3
0: X O O X
1: X O O O
where O indicates an empty seat, and X indicates a full one. Economy
Class should look similar, except with columns numbered 0 to 5.
Seat.java
Represents a seat on a flight. Each seat must store whether it is a window
seat, and whether it's an aisle seat. (Note that since some seats in Economy
Class are neither, and some seats in Club Class are both, one boolean will
probably be insufficent.) Each seat must also be able to have one person
assigned to it, though it may also be empty.
Constructor:
There should be one constructor, which takes two booleans as parameters.
One should specify whether the seat is a window seat, and the other
should specify whether it's an aisle seat.
Required methods:
getPerson
This should take no arguments, and return the Person Object stored
within this Seat Object. (If there is no person assigned to the
seat, it is OK to return null. Just make sure you check for it
whenever you call getPerson().)
setPerson
This should take one argument, a Person Object, and return nothing.
Calling this method should have the effect of assigning the
specified Person to this Seat.
isWindow
Takes no arguments, and returns a boolean depending on whether this
is a window seat.
isAisle
Takes no arguments, and returns a boolean depending on whether this
is an aisle seat.
Person.java
Represents a person. A Person has a name and a nationality.
Constructor:
There should be one consructor. It should take two Strings as arguments:
the person's name, and the person's nationality.
Required methods:
getName
Takes no arguments, and returns a String, the Person's name.
getNationality
Takes no arguments, and returns a String, the Person's nationality.
Location.java
This class is already implemented for you, and you should not change it.
You should use a Location object wherever you find you need to return a
seat's location, for example in the format
return new Location(true, 0, 1);
This would have the effect of specifying seat 0,1 in the Club Class.
Note: Coursemarker will only mark files it knows about. If you create other
.java files, they will not be marked, and your code will probably not work.
Error Conditions
================
At the Flight Booking Menu, if the user enters and invalid menu option, print
ERROR: Invalid menu choice!
At the Aeroplane Details menu, if the user enters a number of rows less than
zero, print the message
ERROR: Invalid Row Count
At the Available flights menu (shown when making a booking, or printing a
manifest) if the user enters an invalid flight number, print the message
ERROR: Invalid menu choice!
At the Seat Type menu, if the user enters anything other than 'c' or 'C', treat
it as if they intended to press 'e', ie you should NEVER print an error message
from this menu.
At the Seat Selection menu, if the user does not make a valid menu choice, treat
it as if they had intended to press '4', ie you should NEVER print an error
message from this menu.
When asking the user if they wish to book another seat, accept 'y' or 'Y' as
yes, and any other character as no. You should not print an error message here.
When booking a specific seat, if the requested seat is already booked, print the
message
ERROR: Seat already taken
and prompt for another row and column.
When booking a specific seat, if the provided row or column number is invalid
(eg if is less than zero or greater than the number of rows/columns) print the
message:
ERROR: Invalid row number
or
ERROR: Invalid column number
as appropriate, and then prompt for another row and column.
When booking any window seat, if there are no window seats available in the
specific seating class, print the message
Sorry, no window seats left
Similarly, if there are no aisle seats left in the specific seating class when
booking an aisle seat, print the message
Sorry, no aisle seats left
In both of the above cases, prompt the user if they would like to book another
seat, as if they had successfully made a booking.
If the user tries to make a booking on a flight that is fully booked, print the
message
Flight is fully booked, Sorry
