java - 如何从货币代码中获取国家代码/名称

Question

鉴于我有货币代码，我如何获得适用于该货币的国家/地区代码/名称？我了解货币和国家/地区之间可能存在 1:n 映射，在这种情况下，如何获取适用该货币的所有国家/地区？

Answer 1

nv-i18n 中的

CurrencyCode 类库有 getCountryList() 方法，它返回使用该货币的国家列表。下面是一个示例命令行应用程序。

import java.util.List;
import com.neovisionaries.i18n.CountryCode;
import com.neovisionaries.i18n.CurrencyCode;

public class CurrencyToCountryList
{
    public static void main(String[] args)
    {
        // For each currency code such as EUR and USD.
        for (String code : args)
        {
            // Get a CurrencyCode instance.
            CurrencyCode currency =
                CurrencyCode.getByCode(code);

            if (currency == null)
            {
                // The code is invalid.
                System.out.format("'%s' is invalid.\n", code);
                continue;
            }

            System.out.format("%s (%s) is used by:\n",
                currency, currency.getName());

            // Get the list of countries using the currency.
            List<CountryCode> countryCodeList =
                currency.getCountryList();

            // For each country.
            for (CountryCode country : countryCodeList)
            {
                // Print the country code and the country name.
                System.out.format("\t%s: %s\n",
                    country, country.getName());
            }
        }
    }
}

如果你像这样运行这个应用程序:

$ java -cp nv-i18n-1.15.jar:. CurrencyToCountryList USD

您将得到如下所示的结果:

USD (US Dollar) is used by:
  AS: American Samoa
  BQ: Bonaire, Sint Eustatius and Saba
  EC: Ecuador
  FM: Micronesia, Federated States of
  GU: Guam
  HT: Haiti
