Is there an open source java enum of ISO 3166-1 country codes

Does anyone know of a freely available java 1.5 package that provides a list of ISO 3166-1 country codes as a enum or EnumMap? Specifically I need the "ISO 3166-1-alpha-2 code elements", i.e. the 2 character country code like "us", "uk", "de", etc. Creating one is simple enough (although tedious), but if there's a standard one already out there in apache land or the like it would save a little time.

This code gets 242 countries in Sun Java 6:

String[] countryCodes = Locale.getISOCountries();

Though the ISO website claims there are 249 ISO 3166-1-alpha-2 code elements, though the javadoc links to the same information.

There is an easy way to generate this enum with the language name. Execute this code to generate the list of enum fields to paste :

 /**
  * This is the code used to generate the enum content
  */
 public static void main(String[] args) {
  String[] codes = java.util.Locale.getISOLanguages();
  for (String isoCode: codes) {
   Locale locale = new Locale(isoCode);
   System.out.println(isoCode.toUpperCase() + "(\"" + locale.getDisplayLanguage(locale) + "\"),");
  }
 }

I have created an enum, which you address by the english country name. See country-util.
On each enum you can call getLocale() to get the Java Locale.

From the Locale you can get all the information you are used to, fx the ISO-3166-1 two letter country code.

public enum Country{

    ANDORRA(new Locale("AD")),
    AFGHANISTAN(new Locale("AF")),
    ANTIGUA_AND_BARBUDA(new Locale("AG")),
    ANGUILLA(new Locale("AI")),
    //etc
    ZAMBIA(new Locale("ZM")),
    ZIMBABWE(new Locale("ZW"));

    private Locale locale;

    private Country(Locale locale){
        this.locale = locale;
    }

    public Locale getLocale(){
        return locale;
    }

Pro:

  • Light weight
  • Maps to Java Locales
  • Addressable by full country name
  • Enum values are not hardcoded, but generated by a call to Locale.getISOCountries(). That is: Simply recompile the project against the newest java version to get any changes made to the list of countries reflected in the enum.

Con:

  • Not in Maven repository
  • Most likely simpler / less expressive than the other solutions, which I don't know.
  • Created for my own needs / not as such maintained. - You should probably clone the repo.

I found the IsoCountry list here, it has 2 and 3 char country codes
