Question

Write a function, sumdivisors, that takes a single integer parameter and returns the sum of all the divisors of the parameter (including 1). So sumdivisors(6) will return 6 as 1+2+3=6. Note you may use a wrapper function or default parameters.

Answer 1

//TestCode.java
import java.util.Scanner;

public class TestCode {

    public static int sumdivisors(int n){
        int sum = 0;
        for(int i = 1;i<n;i++){
            if(n%i == 0){
                sum += i;
            }
        }
        return sum;
    }

    public static void main(String[] args){
        System.out.println(sumdivisors(6));
    }
}
