Question

This program should create and populate a two dimensional array containing four rows and two columns of integer values. It should prompt the user and ask them to enter in the column they wish to average. It should then average all of the values in the column selected by the user

Fix this program

package chapter8_Test;

import java.util.Scanner;

public class Chapter8

{

public static void main(String[] args)

{

int[] matrix = {{1,2},{3,4},{5,6},{7,8}};

int columnChoice;

int columnTotal = 0;

double columnAverage = 0;

Scanner input = new Scanner(System.in);

System.out.print("Which column would you like to average (1 or 2)? ");

columnChoice = input.nextInt();

for(int row = 0;row < matrix.length;++row)

{

columnTotal += matrix[row][columnChoice];

}

columnAverage = columnTotal / (float) matrix.length;

System.out.printf("\nThe average of column %d is %.2f\n", columnAverage, columnAverage);

}

}
