How to write a recursive method to return the sum of digits in an int?

Question

So this is my code so far.

    public int getsum (int n){
        int num = 23456;
        int total = 0;
        while (num != 0) {
            total += num         


        

Answer 1

I see a lot of solutions on here, but not one in which seems as simple as what follows. I've tested it countless times and it works no problem:

public int sumDigits(int n) {
  if (n == 0){
    return 0;
  }
  else{
    return n%10 + sumDigits(n/10);
  }
}
