You are most welcome to check your file with your lab tutor before your submission. No excuse will be accepted due to file corruption, absence from lecture or lab classes where details of lab requirements may be given. Please make sure that you attend Lecture EVERY WEEK as low attendance may result in academic penalty or failure of this unit. MITS4002 Project Copyright © 2015-2019 VIT, All Rights Reserved. Page 2 Programming Project Part 1: Arrays & Inheritance Submission deadline: 5 pm, Monday, Lesson 12 Marks: The project is assessment for 25% of final mark for the subject. The project is composed of two parts: Part 1 and Part 2. 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 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. 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 MITS4002 Project Copyright © 2015-2019 VIT, All Rights Reserved. Page 3 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.

Details
In this assignment, we developed 4 different following classes:
1. LuckyGame: This class represents a single lucky game in the assignment project. It is an abstract class and the subclasses of LuckyGame class will define the abstract methods of this abstract class. The data members and methods are accessible to the subclasses and it can be used as per the requirement. The following is the definition of the abstract class LuckyGame.
import java.util.Random;
abstract public class LuckyGame {

String gameName;
String dayOfGame;
int numberOfRandoms;
int lowerValue;
int higherValue;
String[] randomNumbers;
public LuckyGame(String gameName, String dayOfGame, int lowerValue, int higherValue) {
this.gameName = gameName;
this.dayOfGame = dayOfGame;
this.lowerValue = lowerValue;
this.higherValue = higherValue;
}

public void createRandomNumbers(){
Random random = new Random();
randomNumbers = new String[numberOfRandoms];
for(int i=0; i randomNumbers[i] = (random.nextInt(higherValue - lowerValue) + lowerValue) + "";
}
}
public String getName() {
return gameName;
}
public String getDay() {
return dayOfGame;
}
abstract public String toString();
abstract public void setNumberOfRandoms();
abstract public void collectUserInput (String input);

}
2. PowerBallGame: This class extends the abstract class LuckyGame. PowerBallGame class represents a single game for Power ball lucky game. It defines all the abstract methods of the super class and checks the winner of the game by randomly selecting the numbers. The winning numbers are then displayed on the screen also with the matches found between winning numbers and the user picks. The following is the definition of the class PowerBallGame:
import java.util.Random;
public class PowerBallGame extends LuckyGame{

private String theInput;
private String powerBall;
int userPicks;
public PowerBallGame(String gameName, String dayOfGame, int lowerValue, int higherValue) {
super(gameName, dayOfGame, lowerValue, higherValue);
this.theInput = "";
}

public String checkWinningNumbers(){
int winNum = 0;

String[] inputVals = theInput.split(" ");
for(int j=0; j < inputVals.length; j++){
for(int i=0; i if(inputVals[j].equals(randomNumbers[i]))
winNum++;
}
}

if(randomNumbers[numberOfRandoms-1].equals(powerBall))
return "No. of winners " + winNum + " you have the POWERBALL";
else
return "No. of winners " + winNum + " you dont have the POWERBALL";

}
@Override
public void setNumberOfRandoms() {
Random random = new Random();
numberOfRandoms = random.nextInt(5) + 5;
super.createRandomNumbers();
}
@Override
public void collectUserInput(String input) {
this.theInput = input;
String[] val = input.split(" ");
this.userPicks = val.length;
this.powerBall = val[val.length-1];
this.setNumberOfRandoms();
}
@Override
public String toString() {
String s = this.getDay() + " " + this.getName() + " numbers are: \n";
for(int i=0; i s += randomNumbers[i] + " ";
}
s += "the POWERBALL is:- " + randomNumbers[numberOfRandoms-1] + "\n";
s += this.userPicks + " user picks between " + lowerValue + " and " + higherValue + " are\n";
s += this.theInput + " and the user chosen POWERBALL is:- " + powerBall + "\n";
s += checkWinningNumbers();
return s;
}
}
3. TattslottoGame: This class extends the abstract class LuckyGame. TattslottoGame class represents a single game for Tatts lotto lucky game. It defines all the abstract methods of the super class and checks the winner of the game by randomly selecting the numbers. The winning numbers are then displayed on the screen also with the matches found between winning numbers and the user picks. The following is the definition of the class TattslottoGame:
