用JAVA编写用户输入一个整数,求这个整数的因子和(所谓因子即可以被其整除的数,但本身不算,

public class Test1 {
    public static void main(String[] args) {
        int num = 1845;
        int sum = 0;
        System.out.println("因子：1");
        sum += 1;
        int sqrt = (int)Math.sqrt(num);
        for(int i=2;i            int j = num%i;
            if(j==0){
                System.out.println("因子："+i);
                sum += i;
                int k = num/i;
                System.out.println("因子："+k);
                sum += k;
            }
        }
        System.out.println("因子和："+sum);
    }
}
