如何查找多种语言的国家/地区代码 [英] How to find a country code in multiple languages

问题描述

我的问题是我得到了使用不同语言的国家/地区列表.全部在文本文件中.例如:

My problem is that I got a list of countries in different languages. All in text file. E.g:

pl_PL   Japonia
en_GB   Spain
en_EN   Portugal

我正在寻找一种查找国家/地区代码的方法，因为它知道不同的语言名称，所以我可以用其他语言打印出来.例如:

I am seeking a way to find the code of the country, knowing name in different languages, so i could print it in another languages. E.g:

pl_PL   Japonia    -- translate to english -->     en_EN  Japan
en_EN   Portugal   -- translate to polish  -->     pl_PL  Portugalia

我当时正在考虑为每种语言制作一个哈希图，在其中放置所有可用的国家和代码，但我不知道该如何制作.我已经制作了一张这样的地图，但是我不知道如何制作多种语言.

I was thinking to make a hashmap for each language where I would put all available countries and codes, but I don't have idea how to make it. I made already one map like this, but I don't know how to make it for multiple languages.

    Locale[] allLocs = Locale.getAvailableLocales();
    Map map = new HashMap();
    String country = null;

    for (int j=0; j<allLocs.length; j++) {
        Locale.setDefault(new Locale(langArray[0]));
        String countryCode = allLocs[j].getCountry();

        if (countryCode.equals("")) continue;
        kraj =  allLocs[j].getDisplayCountry();
        map.put(country , allLocs[j]);
    }

推荐答案

也许您尝试的Locale构造出错.您需要从输入文件中检索以下内容:

Maybe the Locale construction went wrong in your attempts. You need to retrieve the following from the input file:

    final Locale locale1 = new Locale("pl", "PL");
    final String country1 = "Japonia";

然后指定目标语言环境:

Then given the target locale:

    final Locale locale2 = new Locale("en", "US");

一个人可以像您一样找到国家.在Java 8中:

One can find the country as you did. In java 8:

    final Locale[] locales = Locale.getAvailableLocales();
    Optional<String> country2 = Stream.of(locales)
            .filter((loc) -> country1.equals(loc.getDisplayCountry(locale1)))
            .map((cloc) -> cloc.getDisplayCountry(locale2))
            .filter((s) -> !s.isEmpty())
            .findAny();
    System.out.println(country2.orElse("not found"));

1. 这会以第一语言搜索显示国家/地区的每个位置.
2. 然后将相应国家/地区的cloc用于第二语言的显示国家/地区.
3. 非空.
