What is printed by the above code?

public class Sum2D {
    public static void main(String[] args) {
        int[][] grid = { {2, 3}, {4, 5} };
        int sum = 0;
        for (int i = 0; i < grid.length; i++) {
            for (int j = 0; j < grid[i].length; j++) {
                if (grid[i][j] % 2 == 0)
                    sum += grid[i][j];
            }
        }
        System.out.println(sum);
    }
}
