Java program to add two matrices

import java.util.Scanner; //import Scanner class in our program

class demo
{
 public static void main(String…s)
   {
    int i,j,n,m;
    Scanner sc=new Scanner(System.in); //used to read from keyboard

    System.out.print(“Enter number of rows:”);
    m=sc.nextInt();
    System.out.print(“Enter number of columns:”);
    n=sc.nextInt();

   int a1[][]=new int[m][n];
   int a2[][]=new int[m][n];
   int a3[][]=new int[m][n];

   System.out.print(“nEnter elements of first matrix:n”);
   for(i=0;i<m;++i)
   for(j=0;j<n;++j)

   a1[i][j]=sc.nextInt();
   System.out.print(“nEnter elements of second matrix:n”);
   for(i=0;i<m;++i)
