In this post we focuses on adding two matrices.Before adding two matrices we need two matrices of same order.i.e is number of rows,columns in matrix 1 should be equaled to number of rows,columns in matrix 2.The procedure for adding two matrix is:

**1. Input:Take two,matrix of same order from the user,can be of different elements.**

**2. Procedure:For summation of two matrix we need to add the elements of the corresponding position and store them in the same position.**

**3. Display:After the summation we display the result stored in the matrix.**

By following the above steps we can write a simple code:

import java.util.*;
class addition
{
int n,i,j;
void setdata()
{
Scanner in = new Scanner(System.in);
int[][] mat1 = new int[n+1][n+1];
int[][] mat2 = new int[n+1][n+1];
int[][] resltmat = new int[n+1][n+1];
System.out.println("Enter the elements of 1 matrix:");
for(i=1;i < n+1;i++)
{
for(j=1;j < n+1;j++)
{
System.out.println("Enter the element of "+ i +" row "+ j +" column:");
mat1[i][j] = in.nextInt();
}// end of j loop
}// end of i loop
System.out.println("Enter the elements of 2 matrix:");
for(i=1;i < n+1;i++)
{
for(j=1;j < n+1;j++)
{
System.out.println("Enter the element of "+ i +" row "+ j +" column:");
mat2[i][j] = in.nextInt();
}// end of j loop
}// end of i loop
System.out.println("Resultant matrix is:\n");
for(i=1;i < n+1;i++)
{
for(j=1;j < n+1;j++)
{
resltmat[i][j] = mat1[i][j]+mat2[i][j]; //adds the elements of the matrxi 1,2
System.out.print(resltmat[i][j] + " ");
}
System.out.print("\n\n");
}
}
}
class matadd
{
public static void main(String arg[])
{
Scanner in = new Scanner(System.in);
addition ob = new addition();
System.out.print("Enter the order of the matrix you need to enter:");
ob.n=in.nextInt();
ob.setdata();
}
}

The output of the above program is:
