You will be creating a small guessing game which consists

You will be creating a small guessing game which consists of two classes, GameDriver and RandGuessGame. The game will randomly generate five numbers between 1 and 100, show the player only the first and last, and they must guess if the sum of all numbers is greater than 250. The GameDriver is provided for you, as is starter code for RandGuessGame. You must write the remainder of RandGuessGame to the provided specifications. Javadocs for these classes are in the starter project you will download from Web-CAT. There is also a text file which provides some example output.

Paper For Above Instructions

The objective of this paper is to outline the implementation of a small guessing game using two classes: GameDriver and RandGuessGame. This game is designed to engage players in a fun and interactive manner while also providing an opportunity to delve into Java programming and object-oriented design principles.

Overview of the Game Design

The guessing game revolves around a simple yet effective concept. It generates five random integers between 1 and 100. The player is presented with the first and the last numbers, but they do not see the middle three. The player's task is to determine whether the sum of all five numbers exceeds 250. This format introduces an element of strategy and critical thinking as the player makes their guesses based on incomplete information.

Class Design

To effectively structure our game, we need to design two primary classes: GameDriver and RandGuessGame.

1. RandGuessGame Class

The RandGuessGame class is where the main logic of the game resides. It is responsible for generating the random numbers, calculating their sum, and managing the game flow. Below is a detailed breakdown of this class:

  • Variables: This class will have an array to store the five randomly generated numbers, and an integer to keep track of the player's guess.
  • Constructor: The constructor will generate the five numbers and calculate their sum upon instantiation.
  • Methods: The class will include methods for generating numbers, displaying the numbers to the player, and receiving guesses.

2. GameDriver Class

The GameDriver class is the entry point of the application. It contains the main method that initializes the game and interacts with the player. Here, we set up the game and gather user input:

  • Initialization: The main method will create an instance of the RandGuessGame class.
  • User Interaction: This class will facilitate communication with the player, asking them to make their guesses and providing feedback based on their responses.

Implementation of RandGuessGame Class

import java.util.Random;


import java.util.Scanner;


public class RandGuessGame {


private int[] numbers;


private int sum;


public RandGuessGame() {


numbers = new int[5];


generateNumbers();


calculateSum();


}


private void generateNumbers() {


Random rand = new Random();


for (int i = 0; i 

numbers[i] = rand.nextInt(100) + 1; // Number between 1 and 100


}


}


private void calculateSum() {


for (int number : numbers) {


sum += number;


}


}


public void displayNumbers() {


System.out.println("First number: " + numbers[0]);


System.out.println("Last number: " + numbers[4]);


}


public boolean checkGuess(boolean guess) {


return (sum > 250) == guess;


}


public int getSum() {


return sum;


}


}

Implementation of GameDriver Class

import java.util.Scanner;


public class GameDriver {


public static void main(String[] args) {


Scanner scanner = new Scanner(System.in);


RandGuessGame game = new RandGuessGame();


game.displayNumbers();


System.out.println("Do you think the sum of the five numbers is greater than 250? (true/false)");


boolean playerGuess = scanner.nextBoolean();


if (game.checkGuess(playerGuess)) {


System.out.println("Correct! The sum is: " + game.getSum());


} else {


System.out.println("Wrong! The sum is: " + game.getSum());


}


scanner.close();


}


}

Conclusion

This simple guessing game serves as an excellent exercise for understanding the basics of Java programming and object-oriented design. By creating two distinct classes, we separate the logic of the game from the execution, which is a best practice in software development. The approach offers players an engaging experience while allowing developers to enhance their programming skills through practical application.
