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

int getSum(int N)
{
    int totalN = 0;

    totalN += (N% 10);
    N/= 10;

    if(N == 0)
        return totalN;
    else 
        return getSum(N) + totalN;
}
