  • `there can be 3 languges like German, French and` ... **Italian** (Suisse-Italian), not UK English! Well, they are all Switzerland variants of German, French and Italian. – Phantômaxx Mar 28 '15 at 20:16

    So which of the three languages of Switzerland do you expect get? If not all three, it's not clear what you want. There's no "the" language code for Switzerland. – alexis Mar 28 '15 at 20:24

    If you already know you want German, rather than either of the other, equally official, languages, why not just use "de"? Or use `new Locale("ch", "de")` to create a Locale object for the combination of Switzerland and German. – Patricia Shanahan Mar 28 '15 at 22:01

This program prints the language codes for all available locales for Switzerland. It can easily be modified to e.g. return a List<String> of language codes. Picking the one you want is left as an exercise for the reader - the Swiss have not chosen to pick a single preferred language for their country.

import java.util.Locale;

public class Test {
  public static void main(String[] args) {
    Locale[] all = Locale.getAvailableLocales();
    for (Locale locale : all) {
      String country = locale.getCountry();
      if(country.equalsIgnoreCase("CH")){
        System.out.println(locale.getLanguage());
      }
    }
  }
}

Output:

fr
de
it

    BTW: if you need the country's name in a specific locale's language: https://www.mkyong.com/java/display-a-list-of-countries-in-java/ – Kawu Dec 30 '19 at 16:40

You can use following constructor of Locale - 

   Locale(String language, String country)

For USA (code: US) the language is English (code "en"). So you can do this - 

Locale locale = new Locale("en", "US");

  • Can I use like below : Locale locale = new Locale("CH"); String language = locale.getDisplayLanguage(). is it correct ? – Android_programmer_office Mar 28 '15 at 20:22

    This answer is pretty unrelated to the question. @Android_programmer_office: no this is not correct. In fact, you cannot dereference a language from a country code directly. See Patricia's answer for further information. – itchee Mar 28 '15 at 21:06
