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

Short, recursive and does the job:

int getsum(int n) {
   return n == 0 ? 0 : n % 10 + getsum(n/10);
}
