What is the sum of all odd numbers printed by the program?

public class SumOdds {
    public static int sumOdds(int[] arr, int index) {
         if(index == arr.length) return 0;
         if(arr[index] % 2 != 0)
             return arr[index] + sumOdds(arr, index + 1);
         else
             return sumOdds(arr, index + 1);
    }
    public static void main(String[] args) {
         int[] numbers = {2, 3, 5, 6, 7};
         System.out.println(sumOdds(numbers, 0));
    }
}
