Java:货币到区域设置映射可能吗？

import java.util.Currency;
import java.util.Set;

public class CurrencyExample {
    public static void main(String[] args) {
        Set<Currency> availableCurrencies = Currency.getAvailableCurrencies();
        for (Currency currency : availableCurrencies) {
            System.out.println(currency.getCurrencyCode() + " - " + currency.getDisplayName());
        }
    }
}
