如何在Java或Groovy中获取许多语言的数字的序号后缀 [英] How to get the ordinal suffix of a number for many languages in Java or Groovy

问题描述

我正在构建一个多语言的 grails 网站，我需要获取多种语言的序号后缀，例如英语，法语，西班牙语，德语和意大利语。

I am building a multi-languages grails website and I need to get the ordinal suffix of a number for several languages like English, French, Spanish, German and Italian.

我相信这个问题对于多语言网站所有者来说是相当普遍的。我找到了这篇文章，它提供了一个解决方案，但它只有英文。

I believe that this issue is quite common for multi-languages website owners. I have found this article that provides a solution but it is English only.

例如：

For instance:

/**
 *@value number 
 *@locale Current locale
 *@returns ordinal suffix for the given number
**/
public static String getOrdinalFor(int value, Locale locale) 

会得出以下结果：

will give the following results:

 assert getOrdinalFor(1, Locale.ENGLISH) == "st"
 assert getOrdinalFor(1, Locale.FRENCH) == "er"
 assert getOrdinalFor(2, Locale.ENGLISH) == "nd"
 assert getOrdinalFor(3, Locale.ENGLISH) == "rd"
 assert getOrdinalFor(4, Locale.ENGLISH) == "th"
 assert getOrdinalFor(4, Locale.FRENCH) == "ème"

你知道一个库（Java或Groovy）这可以帮助吗？或者你知道一个实现它的算法？

Do you know a library (in Java or Groovy) that can help this? Or do you know an algorithm that implements it?

推荐答案

我认为在很多语言中这种方法是不可能的，因为他们根本没有概念可以由一些字母组​​成的序号作为扩展名。对于第一即德文，您只能写1。或erster/erste/erstes，具体取决于您所编号的属性。

I think in many languages this approach is impossible as they simply have no concept of ordinals that can be composed of a number with some letters as extension. For "1st" i.e. in german you can only either write "1." or "erster"/"erste"/"erstes" depending of genus of what you are numbering.
