Addition of two Matrices – Java

public class JavaExample {
    public static void main(String[] args) {
        int rows = 2, columns = 4;
        
        // Declaring the two matrices as multi-dimensional arrays
        int[][] MatrixA = { {1, 1, 1, 1}, {2, 3, 5, 2} };
        int[][] MatrixB = { {2, 3, 4, 5}, {2, 2, 4, -4} };
        
        /* 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] + "    ");

}

Output:

| 1 1 1 1 |
| 2 3 5 2 |
