Assignment 5 - Pantomine Ticket Booking

by Anonymous on 15:47 No comments
Assignment brief:
It’s coming up to pantomime season and CIT are planning on staging their first ever pantomime in the Rory Gallagher theatre. You have been asked to design and develop a Java application for box office staff to help them manage the bookings for the theatre.
The program should be generic so that it can, with minimal modification, work for any size theatre with a rectangular arrangement of seats.

Assignment 7 - Database Lotto Quickpick

by Training site on 15:01 No comments
Assignment brief:
The Lotto QuickPick software application that you wrote previously (https://www.dropbox.com/sh/8eb6sg5oad0lg89/3DRtDl6uuz) has been well received and the client is looking to enhance the functionality. They want to add options such as lotto game selection and a checkout screen showing the cost of the game based on how many lines were purchased.
