Translate country name into other language

问题:

I searched for a solution, but I have not found any.

I have this kind of information:

String locale = "en_GB";
String country = "Japonia"; //It means Japan in polish

I need to translate the country name "Japonia" into language indicated in string locale, so "Japan". Is there any way to do it?

Assuming you know both the input language and the desired output language, an alternative approach - iterate the Locale(s) on the system using Locale.getAvailableLocales(), test if the country name matches from the desired in Locale - if so display it in the desired output Locale using getDisplayCountry(Locale)

String country = "Japonia";
Locale outLocale = Locale.forLanguageTag("en_GB");
Locale inLocale = Locale.forLanguageTag("pl-PL");
for (Locale l : Locale.getAvailableLocales()) {
    if (l.getDisplayCountry(inLocale).equals(country)) {
        System.out.println(l.getDisplayCountry(outLocale));
        break;
    }
}

Outputs

Japan

And if you modify the outLocale like

Locale outLocale = Locale.forLanguageTag("es-SP");

you get

Japón

The Java Runtime Library doesn't have a translation API, but the Locale class can be used to get the name of any country in any language, as long as you know the ISO 3166 alpha-2 country code, and the ISO 639 alpha-2 or alpha-3 language code.

Example for country Japan:

Locale countryJapan = new Locale.Builder().setRegion("JP"/*Japan*/).build();
Locale langEnglish  = new Locale.Builder().setLanguage("en"/*English*/).build();
Locale langPolish   = new Locale.Builder().setLanguage("pl"/*Polish*/).build();
Locale langJapanese = new Locale.Builder().setLanguage("ja"/*Japanese*/).build();
Locale langItalian  = new Locale.Builder().setLanguage("it"/*Italian*/).build();
System.out.println(countryJapan.getDisplayCountry(langEnglish));
System.out.println(countryJapan.getDisplayCountry(langPolish));
System.out.println(countryJapan.getDisplayCountry(langJapanese));
System.out.println(countryJapan.getDisplayCountry(langItalian));

Output

Japan
Japonia
日本
Giappone

Yes, you can use a translation API. Like Microsoft's or Google's.
