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

Question

Using Java, Is there a quick way to convert an alpha-2 country code (IN or GB) to the alpha-3 equivalent (IND or GBR)?

I can get the alpha-2 codes with:

String[] codes = java.util.Locale.getISOLanguages();

That's not a problem, actually my application reads in the alpha-2 code, but I need to output the alpha-3 equivalent .

Is there a similar way like above to get the alpha-3 codes?

Any suggestions?

Answer 1

This works -

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

Output:

Country=IND

Answer 2

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)
