Write a JAVA program to determine the subtraction of two matrices.

Aim: Write a JAVA program to determine the subtraction of two matrices.

Program:

import java.util.Scanner;

class SubTwoMatrix

{

   public static void main(String args[])

   {

      int m, n, c, d;

      Scanner in = new Scanner(System.in);

      System.out.println("Enter the number of rows and columns of matrix");

      m = in.nextInt();

      n  = in.nextInt();

      int first[][] = new int[m][n];

      int second[][] = new int[m][n];

      int sum[][] = new int[m][n];

      System.out.println("Enter the elements of first matrix");

      for (  c = 0 ; c < m ; c++ )

         for ( d = 0 ; d < n ; d++ )

            first[c][d] = in.nextInt();

      System.out.println("Enter the elements of second matrix");

      for ( c = 0 ; c < m ; c++ )

         for ( d = 0 ; d < n ; d++ )

            second[c][d] = in.nextInt();

      for ( c = 0 ; c < m ; c++ )

         for ( d = 0 ; d < n ; d++ )

             sum[c][d] = first[c][d] - second[c][d];  //replace '-' with '+' to add matrices

      System.out.println("Sum of entered matrices:-");

      for ( c = 0 ; c < m ; c++ )

      {

         for ( d = 0 ; d < n ; d++ )

            System.out.print(sum[c][d]+"\t");

         System.out.println();

      }

   }

}

Output:
