MITS4002 Research Study

This assessment item relates to the unit learning outcomes as in the unit descriptors.
This checks your understanding about object-oriented software development.
This assessment covers the following LOs.
LO1 Demonstrate understanding of classes, constructors, objects, data types and instantiation; Convert data types using wrapper methods and objects.
LO2 Independently analyse customer requirements and design object-oriented programs using scope, inheritance, and other design techniques; Create classes and objects that access variables and modifier keywords. Develop methods using parameters and return values.
LO3 Demonstrate adaptability in building control and loop structures in an object-oriented environment; Demonstrate use of user defined data structures and array manipulation.
LO4 Create object hierarchies using additional utility methods, application programming interfaces (API) and interfaces, in conjunction with existing classes and objects. LO2 Analyze customer requirements independently and design object-oriented programs using scope, inheritance, and other design techniques; develop classes and objects that access variables and modifier keywords. Create methods that make use of parameters and return values.
LO3 Show adaptability in building control and loop structures in an object-oriented environment; Show use of user-defined data structures and array manipulation.
LO4 Create object hierarchies by combining existing classes and objects with additional utility methods, application programming interfaces (API), and interfaces.
LO5 Demonstrate usage of collection to access data structures effectively and compose fullfledged object-oriented applications.
LO6 Extend the on object-oriented concepts and design patterns introduced in lectures to carry out further research on a chosen object-oriented design pattern or emerging recent programming languages.

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.
Details of these games can be found at http://www.thelott.com
You are required to use arrays and inheritance to code versions of these games.
Note: GAMBLING can be a serious problem for some people. Your lecturer DOES NOT encourage you to gamble.
Summary of Some of the Lottery Games
(From the Help pages of the above web site)
Game Day Description
Tattslotto Saturday 45 balls numbered 1 to 45, from which 8 balls are randomly selected. The first 6 balls are the winning numbers and the last two balls drawn are the supplementary numbers.
Oz Lotto Tuesday 45 balls numbered 1 to 45, from which 9 balls are randomly selected. The first 7 balls are the winning numbers and the last two balls drawn are the supplementary numbers.
Powerball Thursday 35 balls numbered 1 to 35 from which 7 are randomly selected. An eighth ball, the Powerball, is then drawn from a separate machine containing 20 balls numbered 1 to 20.
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.
