/** * Lottery Program * This program is to simulate a lottery * game. First, the user is prompted to enter * how many guesses they want to take. Next, * the user is prompted to enter the list of * guessed numbers. Third, the computer picks * their numbers to guess. Fourth, the grid * replaces zeroes in the number grid. Fifth, * the number of correct guesses is * printed. Finally, the user is prompted to * be asked to play again. * * @author Tanmayi * @version 5/28/2023 */ // Import the scanner and random libraries import java.util.Scanner; import java.util.Random; // Beginning of the Lottery class public class Lottery { // Beginning of the main method public static void main(String[] args) { // Declares and sets the scanner variable Scanner in = new Scanner(System.in); // Declares and sets the random value Random randVal = new Random(); // Declare and sets the 2D array in a grid int[][] numGridAry = new int[8][10]; // Declares and sets the number of guesses int nOfGuesses = 0; // Declares and sets a user guessed number int usrGuessNum=0; // Declares and sets the play again response String playAgResp = "y"; // Beginning of the do loop to run the lotter program while(playAgResp.equals("y")) { // Prints out the lottery rules System.out.println("Welcome to the lottery game!"); System.out.println("You need to guess between 3 and 15 numbers."); System.out.println("The program will generate 20 random numbers between 1-80."); System.out.println("If your numbers match any of the random numbers, you win!"); System.out.println(); // Prints out the grid of numbers 1 to 80 System.out.println("Lottery number grid:"); // Beginning of the outer loop to print the number grid for (int i = 0; i < 8; i++) { // Beginning of the inner loop to print the number grid for (int j = 0; j < 10; j++) { numGridAry[i][j] = i * 10 + j + 1; System.out.printf("%2d ", numGridAry[i][j]); } // Ending of the inner loop to print the number grid
