What does the code print when executed?

public class ModifyMatrix {
    public static void main(String[] args) {
        int[][] matrix = { {1,2}, {3,4} };
        for (int[] row : matrix) {
            for (int n : row) {
                n = n + 5;
            }
        }
        System.out.print(matrix[0][0] + " " + matrix[1][1]);
    }
}
