Country to Currency Mapping

[Jacob Thomas]

Given a ISO 3166-1 country code, what is the best possible way to get the corresponding ISO 4217 currency code in Java? For example, for the country code 'US' I should get the corresponding currency code 'USD'.

Is there any library or utility class providing such facility in Java? I had a look at the Currency class in java but, that gives the currency code for a given locale. Thanks!

Thinking about it, I found a solution and is given below:

 
import java.util.*;
 
public class LocaleTest {
 
  public static void main(String[] args) {
 
     Locale loc = new Locale("en", "FR");
     Currency cur = Currency.getInstance(loc);
 
     System.out.println("Currency code is: " + cur.getCurrencyCode());
  }
}
 

In this code, I am constructing a new Locale with the correct ISO country code for France(FR) and the wrong language(en). I am pssing this Locale instance to the Currency class and thereby, obtaining the Currency Code for the given country.

Is there any problem by constructing a Locale instance by passing a wrong langauge? Thanks!

will this work?

Apparently it will, since half an hour before your post Jacob has posted a working solution that uses Currency.

If you are using it for only this, then no. Currency.getInstance(Locale) only uses the Locale's country.

I wouldn't use the Locale for other means though, since I expect you to run into unexpected results then.
