Java: Adds up columns and rows of given table as shown in the specified figure

Java Basic: Exercise-242 with Solution

Your task is to develop a small piece of spreadsheet software. Write a Java program that adds up the columns and rows of a given table as shown in the specified figure.

Pictorial Presentation:

Java Basic Exercises: Adds up columns and rows of given table as shown in the specified figure.

n (the size of row and column of the given table)
1st row of the table
2nd row of the table
n th row of the table
The input ends with a line consisting of a single 0.
For each dataset, print the table with sum of rows and columns.

Sample Solution:

Java Code:

 import java.util.*;

public class Main {     
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
          System.out.println("Input number of rows/columns (0 to exit)"); 
            int n = sc.nextInt();
            int[][] map = new int[n+1][n+1];
            for(int i=0;i<n;i++){
                for(int j=0;j<n;j++){
                    map[i][j] = sc.nextInt();
                    map[i][n] += map[i][j];
                map[n][n] += map[i][n];
            for(int i=0;i<n;i++){
                for(int j=0;j<n;j++){
                    map[n][i] += map[j][i];
            for(int i=0;i<n+1;i++){
                for(int j=0;j<n+1;j++){
                    System.out.printf("%5d", map[i][j]);

Sample Output:

Input number of rows/columns (0 to exit)
25 69 51 26
68 35 29 54
54 57 45 63
61 68 47 59
   25   69   51   26  171
   68   35   29   54  186
   54   57   45   63  219
   61   68   47   59  235
  208  229  172  202  811
