Java program to find the sum of all elements of a Matrix.

SUM OF ALL ELEMENTS OF MATRIX.

                                                              In this program we have calculated sum of all elements of matrix. We have used sum  variable that is initialize to value 0 . Then by using for loop we have added single matrix element and in this way we got our result.

JAVA CODE :) 

import java.util.Scanner;

public class Matrix

{

  public static void main(String[] args)

  {

    int m,n,i,j,sum=0;

    Scanner sc= new Scanner(System.in);

    System.out.print("Enter number of rows:");

    m=sc.nextInt();

    System.out.print("Enter number of columns:");

    n=sc.nextInt();

    System.out.println("Enter "+m*n+" elements of Matrix:");

    int a[][] = new int[m][n];

    for(i=0;i<m;i++)

    {

      for(j=0;j<n;j++)

      {

         a[i][j]=sc.nextInt();

      }

    }

    sc.close();

    System.out.println("You Entered matrix is:");

    for(i=0;i<m;i++)

    {

      for(j=0;j<n;j++)

      {

        System.out.print(+a[i][j]+"  ");

        sum=sum+a[i][j];

      }

      System.out.println();

   }

   System.out.print("Sum of all elements of Matrix is:"+sum);

}

}

INPUT && OUTPUT :)
