Project - Tattslotto
Programming Project
Part 1: Arrays & Inheritance
Problem Description
This project is based on the design, and implementation in Java, of the seven different Lottery games being Saturday Tattslotto, Oz Lotto and Powerball.
In Part 1 of the project, you are asked to use arrays and inheritance to code versions of these games and in Part 2 to create an appropriate GUI that writes to a report file.
Summary of Some of the Lottery Games
(From the Help pages of the above web site)
You will notice from your research and examination of the table that all games have several things in common.
All games
• have a name,
• run on a day of the week
• have a set of randomly generated numbers.
Also, each of the randomly generated numbers have a minimum and maximum possible value, for example: For Powerball, the minimum value is 1 and the maximum value is 35.
An abstract class, LuckyGame can be used to represent the generic concept of a game of chance. A suitable partial design is shown in the following UML diagram. In the UML diagram:
• The LuckyGame class represents the generic concept of a game of chance and therefore is to be declared as an abstract class. It contains two abstract methods setNumberOfRandoms( ) and collectUserInput (String input). The LuckyGame class also contains an array of String which is used to record the randomly generated numbers used by each object of LuckyGame type.
• The class TattslottoGame is a LuckyGame and it thus should implement code for
LuckyGame's two abstract methods as well as its own constructor and any other methods.
• The games SaturdayTattslotto and Oz Lotto are all instances of the class
TattslottoGame.
• You can implement the remaining class games in any manner you believe appropriate.
For example, class PowerBallGame can be implemented using either using
o Option 1: the class PowerBallGame is a LuckyGame and thus should implement code for LuckyGame's two abstract methods as well its own constructor and other methods.
o Option 2: the class PowerBallGame is a TattslottoGame and thus should implement code for its own constructor and other methods.
• You have been provided with some code for the class TestGames, which is a text-based application used to create instances of games and test all of their respective behaviours.
• To collect user input for all games, a class UserInput is needed. It should collect user input and deal with any problems in the input, such as repeat numbers or numbers outside the possible range of values.
Programming Project
Part 2: Graphical User Interfaces/Applets & Files & Exceptions
In Part 1 of the project, you are asked to use arrays and inheritance to code versions of 7 Lottery games. In Part 2, using swing classes wherever possible, you need to create an applet for players. The applet should allow a player to choose and run a game of their choice and find out the results of their game. Each time a game is played, the applet writes information about the game to a file called report.txt. This information would be similar to that shown as sample output for Part 1.
