Consider and understand the scenario that follows. Debug the program in order for it to run as stated in its specification.. Underline/Encircle the changes you have made. The program below, when ran, will let the user roll a pair of dice n-times (i.e. generate a number between 1 and 6), where n is a positive integer entered by a user. The program then outputs the pair of numbers rolled by the dice, as well as the sum of the numbers rolled by each pair of dice. The pairs of numbers are stored in a 2-dimensional array, and the sum of each pair are stored in a single-dimensional array. import java.util.Scanner; import java.util.Random; public class Java{ public static void main (String() args) { Scanner input = Scanner(System.in); System.out.print("Enter the amount of times a pair of dice will roll: "); int times = keyboard.nextInt(); int[] dicePairs = rollDicePairs(times); System.out.println("The rolled pairs of numbers are:"); printDicePairs(dicePairs); System.out.println("The sum of each pairs of numbers are:"); int[][] dicePairsSums = addDicePairs(dicePairs); printDicePairsSums(dicePairsSums); } public static double[][] rollDicePairs(int times){ int[][] dice = new int[times][2]; Random die = new Random(); for(int x=0; x<times;x++){ for(int y=0; y<2; y++){ dice[x][y] = 1+die.nextInt(6); } } return dice; } public static void printDicePairs(int[][] dicePairs){ for(int[] pair: dicePairs){ for(int roll: pair){ System.out.print(roll+" "); } System.out.println(""); } } public static int[][] addDicePairs(){ int[] pairSums = new int[dicePairs.length]; for(int x=0; x<pairSums.length; x++){ int sum = 0; for(int y=0; y<dicePairs[x].length; y++){ sum+= dicePairs[x][y]; } pairSums[x] = sum; } return pairSums; } public static String printDicePairsSum(int[] dicePairsSums){ for(int sum: dicePairsSums){ System.out.print(sum+" "); } } }
