Question

public static void main(String[] args)
{
    Scanner x=new Scanner(System.in);
    int n=0;int g=0; int term=0;int temp=0;
    int sum=0; int factor=1;
    System.out.print("Input N:");

    n=x.nextInt();
    g=n;
    if (n<=0)
    {
        System.out.println("Please enter a positive integer");
        System.exit(0);
    }

    if (n>0)
    {
        System.out.print("The factors are:");

        while (factor<n)
        {
            if (n%factor==0)
            {
                System.out.print(factor+",");
            }
            factor++;
        }
    }
}

如果我输入数字8，则因子是1,2和4.我想要实现的是添加因子8，即1,2和4，这将导致7。

Answer 1

import java.util.Scanner;

public class Demo {
public static void main(String[] args)
{
    Scanner x=new Scanner(System.in);
    int n=0;int g=0; int term=0;int temp=0;
    int sum=0; int factor=1;
    System.out.print("Input N:");

    n=x.nextInt();
    g=n;
    int number = 0;
    if (n<=0)
    {
        System.out.println("Please enter a positive integer");
        System.exit(0);
    }

    if (n>0)
    {
        System.out.print("The factors are:");

        while (factor<n)
        {
            if (n%factor==0)
            {
                System.out.println(factor+",");
                number+=factor;
            }
            factor++;
        }
    }
    System.out.println("Sum = "+number);
}
}

import static java.lang.System.*;
import java.util.*;
import java.io.*;

public class Main
{
    public static void main(String[] args)
    {
        Scanner kb = new Scanner(in);
        out.print("Enter a number: ");
        int num = kb.nextInt();
        int sum = 0;
        int x = 1;
        for(x = 1; x <= num; x++){
        if (num % x == 0){
        sum = sum + x;
          } 
    }
        out.print(sum);
}
}
