为了方便和意义完整，factor我是包括input本身，如果sum of factor 不需要 input 本身，那：再减掉 input 的 ...

只要增加几个 looping 就可以了，然后用一个list来记录input的number，我举个例子：
  1. Scanner sc = new Scanner(System.in);
  2. S.O.P("How many number want to test? ");
  3. int size = sc.nextInt();

  5. List<Integer> numbers = new ArrayList(0);
  6. for (int i=0;i<size;i++) {
  7.   S.O.P("Number " + (i+1) + "?");
  8.   int input = sc.nextInt();
  9.   numbers.add(input);
  10. }

  12. for (Integer num : numbers) {
  13.   printResult(sumOfFactors(getFactors(num)), num);
  14. }
复制代码
这个是直接打的，没测试，逻辑大概就是这样而已。
PS: S.O.P = System.out.println
