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

Try this:

int getSum(int num)
{
    total = total + num % 10;
    num = num/10;
    if(num == 0)
    {
        return total;
    } else {
        return getSum(num);
    }
}
