java.util.Currency
si-global.com/"> BSi web site for more information, including a table of currency codes.
The class is designed so that there's never more than one Currency instance for any given currency. Therefore, there's no public constructor. You obtain a Currency instance using the getInstance methods. @since 1.4

     * are reasonable for the currency's default fraction digits.
