Addition of two matrix in JAVA

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:
matrix_addition
