java - If you have the ISO country code `US`, `FR`, how do you get the Locale code (`Locale.US`, `Locale.FRANCE`)? -


if have country code us, fr (iso-3166-1 alpha-2 country code), how locale code (locale.us, locale.france) this:

system.out.println(decimalformat.getcurrencyinstance(locale.us).format(12.34)); system.out.println(decimalformat.getcurrencyinstance(locale.france).format(12.34));  $12.34 12,34 €

you can't, because locale used hold language, not country. can hold language specific country, , specific variant in country, it's language first. , there no one-to-one relationship between language , country. languages spoken in various countries, , many countries have several languages.

if had country code language, use new locale(code). country code, can call getavailablelocales, loop through results, , find 1 has country code. there might several ones.
