Cinnamon Cinema

Develop a program to allocate seats to customers purchasing tickers for a movie theatre.

Requirements

The movie theatre has 15 seats, arranged in 3 rows of 5

Rows are assigned a letter from A to C

Seats are assigned a number from 1 to 5

As a Cinnamon Cinemas Movie Theatre Manager I want to allocate seats to customers So that I can control reserved seating for the theatre

GIVEN a customer wants to request some tickets

WHEN they request a number of seats between 1 and 3 for a movie

THEN the customer should be allocated the required number of seats from the available seating plan

AND the seats should be recorded as allocated

Acceptance criteria

Write a program that allocates seats based on a random integer between 1 and 3

Your program should allocate the required number of seats from the available seats starting from A1 and filling the auditorium from left to right, front to back

All of the seats are available for sale when the program starts

Once there are not enough seats available to be allocated then the program can halt

Design

UML Class Diagram

BookingService - provides methods to add and retrieve movies, book seats, generate tickets and get customer list

Cinema - has name of cinema and generates SeatingPlan. Passed into BookingService

Movie - has movie details (name, time). Each movie has its own SeatingPlan

SeatingPlan - generates seats, maintains count and list of available seats and method to reserve seats

Seat - has seat row and number, allocation status and customer id (if allocated)

Ticket - has details of movie and seats

Customer - maintains list of allocated tickets

Seat selection

The requirement to halt on not enough seats available to be allocated needs some clarification.
This could mean the program is halted when a customer requests 3 seats and there are only 2 remaining, or that booking remains open until the final seats are taken. The program implements the latter for commercial reasons!

Building and Running the application

Once cloned, the application can be built using the following Maven command:

mvn compile package

The unit tests will be executed as part of the build process which produces a jar file in the tagret directory.

To run the application, from the command line, enter:

java -jar target/cinnamon-cinema-1.0-SNAPSHOT.jar

No user input is required.The output shows each booking request and whether it has been successful until all seats are booked. A list of customers with the seat allocation is then produced.

Future enhancements

Multiple movies available for booking

Take into consideration the date and time of the movie

Different seating plan type

Multiple screens within the cinema

Improved automatic seat selection to keep customers on the same row

Customer selection of seats

Multiple customers booking at the same time (a lot to consider here!)
