Question

java with arrays (no array list as we didn't learn it in this course we study classes and arrays so far)

third time i post this, always wrong answers!! please include program output sample!

creat a new program that simulates the game of lotto using ARRAYS.

- the user will input 6 numbers (integers), ranging from 1 to 59.

- the computer willl randomly pick the winning numbers (6 of them and the "Bonus" number)

- to win first prize the user must match all of the 6 numbers.

- to win second prize, the user will must match 5 of 6 numbers AND the bonus number.

** Numbers CANNOT be generated twice, for example 6,18,18,50,52,55 is not valid as 18 appears twice.

** winning numbers (via the computer) are always presented in ascending order.

Explanation / Answer

/*LotteryGame.java java code to find the prize won in lottery */

import java.util.*;

public class LotteryGame {
/*The main method is the program's starting point */

public static void main(String[] args){

// array for user entry
int[] userDigits = new int[6];

// array for computer generated numbers
int[] lotteryNumbers = new int[6];

// counnt of same numbers in both array to find the prize.
int sameNum = 0;

Random randNum = new Random();

lotteryNumbers[0] = randNum.nextInt(5) + 1;
lotteryNumbers[1] = randNum.nextInt(10) + 5;
lotteryNumbers[2] = randNum.nextInt(10) + 15;
lotteryNumbers[3] = randNum.nextInt(10) + 25;
lotteryNumbers[4] = randNum.nextInt(10) + 35;
lotteryNumbers[5] = randNum.nextInt(10) + 45;

int bonus_number = randNum.nextInt(5)+ 55;

Scanner keyboard = new Scanner(System.in);

System.out.println("Input ranging from 1 to 59, Enter digit 1: ");
