        /* Declaring a matrix sum, that will be the sum of MatrixA
         * and MatrixB, the sum matrix will have the same rows and
         * columns as the given matrices.

        int[][] sum = new int[rows]
; for(int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { sum[i][j] = MatrixA[i][j] + MatrixB[i][j]; } } // Displaying the sum matrix System.out.println("Sum of the given matrices is: "); for(int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { System.out.print(sum[i][j] + " "); } System.out.println(); } } }

Output:

| 1 1 1 1 |
