Java code to convert country codes alpha-2 (IN) to alpha 3 (IND)

Yes, simple create a Locale and get if from the locale:

String alpha3Country = new Locale("en", alpha2County).getISO3Country();

BTW: getISOLanguages() returns language codes (lowercase), getISOCountries() return country codes (uppercase)

This works -

    Locale locale = new Locale("en","IN");
    System.out.println("Country=" + locale.getISO3Country());

Output:

Country=IND
