How to convert country name into currency code?

Question

Suppose I have country name as USA .So I want to convert to USD.I have only country name from webservice.

I have tried this code but how to convert country name into Locale object. Can anybody suggest in this problem?

String countryName=jsonObject.getString("country");

Locale takes a language code as a parameter to constructor, not country name: https://docs.oracle.com/javase/7/docs/api/java/util/Locale.html#Locale(java.lang.String) — 1615903, Nov 11 '16 at 11:31
Just pointing out the problem in your code - why would you expect it to work since it's clearly documented that it wont? — 1615903, Nov 11 '16 at 11:33

Provide country code instead of country name

public static void main(String[] args) throws InterruptedException {
Map<String, String> countries = new HashMap<>();
for (String iso : Locale.getISOCountries()) {
    Locale l = new Locale("", iso);
    countries.put(l.getDisplayCountry(), iso);
}

System.out.println(countries.get("Switzerland"));
System.out.println(countries.get("Andorra"));
System.out.println(countries.get("Japan"));
 }

You can also use https://github.com/TakahikoKawasaki/nv-i18n library this is specifically designed for this purpose.

From its GitHub page,

Package to support internationalization, containing ISO 3166-1 country code enum, ISO 639-1 language code enum, etc.

Example specific to this question

String countryName = jsonObject.getString("country");
List<CurrencyCode> codes = CurrencyCode.getByCountry(countryName, false)

Simple example to see available list (from Github page),

// List all the currency codes.
for (CurrencyCode code : CurrencyCode.values())
{
    System.out.format("[%s] %03d %s\n", code, code.getNumeric(), code.getName());
}

// List all the country codes.
for (CountryCode code : CountryCode.values())
{
    System.out.format("[%s] %s\n", code, code.getName());
}
