Java program to subtract two matrices

In this post, we will see how to subtract two matrices in java.I am giving example for 33 matrix. You can extend it to nn matrices.

import java.util.Scanner;

public class MatrixOperator
{
   public static void main(String args[])
   {
       int i, j;
       int mat1[][] = new int[3][3];
       int mat2[][] = new int[3][3];
       int res[][] = new int[3][3];
       Scanner scanner = new Scanner(System.in);

       System.out.print("Enter Matrix 1 Elements : ");
       for(i=0; i<3; i++){
           for(j=0; j<3; j++){
               mat1[i][j] = scanner.nextInt();
           }
       }

       System.out.print("Enter Matrix 2 Elements : ");
       for(i=0; i<3; i++){
           for(j=0; j<3; j++){
               mat2[i][j] = scanner.nextInt();
           }
       }

       for(i=0; i<3; i++){
           for(j=0; j<3; j++){
               res[i][j] = mat1[i][j] - mat2[i][j];
           }
       }

    System.out.println("New Matrix is : ");
       for(i=0; i<3; i++){
           for(j=0; j<3; j++){
               System.out.print(res[i][j]+ " ");
           }
           System.out.println();
       }
   }
}

Output:
