Sorting by Currency

When you sort by currency, Moneta sorts the list based on the lexicographical order of the currency code. For example, a list of money with the currencies USD, EUR, BRL will be sorted to BRL, EUR and USD when sorted in ascending order or USD, EUR, BRL when sorted in descending order. Here's an example.

public class SortMonetaryAmountCurrency {

    public static void main(String[] args) {
        CurrencyUnit dollar = Monetary.getCurrency("USD");
        CurrencyUnit euro = Monetary.getCurrency("EUR");
        CurrencyUnit real = Monetary.getCurrency("BRL");

        MonetaryAmount money = Money.of(9, euro);
        MonetaryAmount money2 = Money.of(10, dollar);
        MonetaryAmount money3 = Money.of(11, real);

        List<MonetaryAmount> resultAsc = Stream.of(money, money2, money3)
                .sorted(MonetaryFunctions
                        .sortCurrencyUnit()).collect(Collectors.toList());//[BRL 11, EUR 9, USD 10]
        List<MonetaryAmount> resultDesc = Stream.of(money, money2, money3)
                .sorted(MonetaryFunctions
                        .sortCurrencyUnitDesc()).collect(Collectors.toList());//[USD 10, EUR 9, BRL 11]

    }
