Class Currency

    java.lang.Object
      java.util.Currency

All Implemented Interfaces:
  Serializable

    public final class Currency

extends Object
implements Serializable

Represents a currency. Currencies are identified by their ISO 4217 currency codes. Visit the 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

Method Detail

### getInstance

    public static Currency getInstance(String currencyCode)

  Returns the `Currency` instance for the given currency code.

  Parameters:
    `currencyCode` - the ISO 4217 code of the currency
  Returns:
    the `Currency` instance for the given currency code
  Throws:
    `NullPointerException` - if `currencyCode` is null
    `IllegalArgumentException` - if `currencyCode` is not a supported ISO 4217 code.

### getInstance

    public static Currency getInstance(Locale locale)

  Returns the `Currency` instance for the country of the given locale. The language and variant components of the locale are ignored. The result may vary over time, as countries change their currencies. For example, for the original member countries of the European Monetary Union, the method returns the old national currencies until December 31, 2001, and the Euro from January 1, 2002, local time of the respective countries.

  The method returns `null` for territories that don't have a currency, such as Antarctica.

  Parameters:
    `locale` - the locale for whose country a `Currency` instance is needed
  Returns:
    the `Currency` instance for the country of the given locale, or null
  Throws:
    `NullPointerException` - if `locale` or its country code is null
    `IllegalArgumentException` - if the country of the given locale is not a supported ISO 3166 country code.

### getCurrencyCode

    public String getCurrencyCode()

  Gets the ISO 4217 currency code of this currency.

  Returns:
    the ISO 4217 currency code of this currency.

### getSymbol

    public String getSymbol()

  Gets the symbol of this currency for the default locale. For example, for the US Dollar, the symbol is "$" if the default locale is the US, while for other locales it may be "US$". If no symbol can be determined, the ISO 4217 currency code is returned.

  Returns:
    the symbol of this currency for the default locale

### getSymbol

    public String getSymbol(Locale locale)

  Gets the symbol of this currency for the specified locale. For example, for the US Dollar, the symbol is "$" if the specified locale is the US, while for other locales it may be "US$". If no symbol can be determined, the ISO 4217 currency code is returned.

  Parameters:
    `locale` - the locale for which a display name for this currency is needed
  Returns:
    the symbol of this currency for the specified locale
  Throws:
    `NullPointerException` - if `locale` is null

### getDefaultFractionDigits

    public int getDefaultFractionDigits()

  Gets the default number of fraction digits used with this currency. For example, the default number of fraction digits for the Euro is 2, while for the Japanese Yen it's 0. In the case of pseudo-currencies, such as IMF Special Drawing Rights, -1 is returned.

  Returns:
    the default number of fraction digits used with this currency

### toString

    public String toString()

  Returns the ISO 4217 currency code of this currency.

  Overrides:
    `toString` in class `Object`
  Returns:
    the ISO 4217 currency code of this currency
