java - 如何使用不同的数据类型进行交换

Question

好吧，假设我有一个 4 个整数的数组 ==

int[] input = new int[]{1,2,3,4};

//now I some how converted these numbers into words and gets an array:-
String Str = new String[]{one,two,three,four};
//then I run a sort method on Str.
Arrays.sort(Str);
//and I got this array in the end  ::: {four,one,three,two}

现在我想将其重新转换为数字(int)，以便我的最终结果应如下所示:- {4,1,3,2}

夏季:- 我想通过其英语(单词)表示对输入 int 数组进行排序

Examples :-

[input]      [convert to words]         [sorting]             [Result]

{1,2,3,4} => {one,two,three,four} =>{four,one,three,two} => 4,1,3,2

{55,23,3,45} =>{fifty five, twenty three, three, fourty five} => {fifty five, fourty five, three, twenty three} => {55,45,3,23}

所以，到目前为止，我设法将输入转换为单词并对其进行排序，但我不知道如何将 Str 数组 转换回其原始 int 数组，如上面的示例所示......

THE REAL QUESTION :- I know i can convert it using loops and array..but i wanna know is it possible to do it using array swapping??[maybe through its indexes??]

P.s:- 很抱歉给您带来任何不便。提前致谢

您可以执行以下操作..

1. 您可以创建一个类并存储它，而不是单独存储。

   public class Numbers {
   String word;
   Integer digit;
   
   public Numbers(String w, int d) {
       word = w;
       digit = d;
   }
   

   }

2. 使用Arrays.sort并创建自定义比较器

   Arrays.sort(n, new Comparator<Numbers>() {
       public int compare(Numbers word, Numbers o) {
           return word.digit.compareTo((o.digit));
       }
   });
