Design a class Colsum to check if the sum of elements in each corresponding column of two matrices…

import java.util.Scanner;

class Colsum
{
    int mat[][];
    int m, n;

    Colsum(int mm, int nn)
    {
        m = mm;
        n = nn;
        mat = new int[m][n];
    }

    void readArray()
    {
        Scanner sc = new Scanner(System.in);
        for (int i = 0; i < m; i++)
            for (int j = 0; j < n; j++)
                mat[i][j] = sc.nextInt();
    }

    boolean check(Colsum A, Colsum B)
    {
        for (int j = 0; j < A.n; j++)
        {
            int sumA = 0, sumB = 0;
            for (int i = 0; i < A.m; i++)
            {
                sumA += A.mat[i][j];
                sumB += B.mat[i][j];
            }
            if (sumA != sumB)
                return false;
        }
        return true;
    }

    void print()
    {
        for (int i = 0; i < m; i++)
        {
            for (int j = 0; j < n; j++)
                System.out.print(mat[i][j] + " ");
            System.out.println();
        }
    }

    public static void main(String[] args)
    {
        Colsum A = new Colsum(3, 3);
        A.readArray();
        Colsum B = new Colsum(3, 3);
        B.readArray();
        if (A.check(A, B))
            System.out.println("Sum of corresponding columns is equal.");
        else
            System.out.println("Sum of corresponding columns is not equal.");
    }
}
