51 47 * Represents a currency. Currencies are identified by their ISO 4217 currency
52 48 * codes. Visit the <a href="http://www.iso.org/iso/en/prods-services/popstds/currencycodes.html">
53 49 * ISO web site</a> for more information, including a table of
54 50 * currency codes.
55 51 * <p>
56 52 * The class is designed so that there's never more than one
57 53 * <code>Currency</code> instance for any given currency. Therefore, there's
58 54 * no public constructor. You obtain a <code>Currency</code> instance using
59 55 * the <code>getInstance</code> methods.
60 56 * <p>
61 57 * Users can supersede the Java runtime currency data by creating a properties
62 58 * file named <code><JAVA_HOME>/lib/currency.properties</code>. The contents
63 59 * of the properties file are key/value pairs of the ISO 3166 country codes
64 60 * and the ISO 4217 currency data respectively. The value part consists of
65 61 * three ISO 4217 values of a currency, i.e., an alphabetic code, a numeric
66 62 * code, and a minor unit. Those three ISO 4217 values are separated by commas.
67 63 * The lines which start with '#'s are considered comment lines. For example,
68 64 * <p>
69 65 * <code>
70 66 * #Sample currency properties<br>
71 67 * JP=JPZ,999,0
72 68 * </code>
73 69 * <p>
74 70 * will supersede the currency data for Japan.
