怎么写阿
题目内容：编写程序，读入一个整数，然后以升序显示它的所有最小因子，并对这些因子进行求和输出。
输入格式:
整数，number为输入的整数， 数组factor存储因子
输出格式：
System.out.print(number + "'s factor series:");
System.out.print(factor + ", ");
System.out.println("\nthe sum of factors is " + sum);
输入样例：
100
输出样例：
100's factor series:2, 2, 5, 5,
the sum of factors is 14 import java.util.ArrayList;
public class Main {
public static void main(String[] args) {
int number = 100;
ArrayList<Integer> factor = new ArrayList<>();
int sum = 0;
for (int i = 2; i <= number; i++) {
while (number % i == 0) {
factor.add(i);
sum += i;
number /= i;
}
}
System.out.print(number + "'s factor series:");
for (int i = 0; i < factor.size(); i++) {
System.out.print(factor.get(i) + ", ");
}
System.out.println("\nthe sum of factors is " + sum);
}
}
