Date and Number Formatting

Java programs use the DateFormat.getDateInstance(int, locale) to parse and format dates in a locale-sensitive manner. Java programs use the NumberFormat.getXXXInstance(locale) method, where XXX can be Currency, Number, or Percent, to parse and format numerical values in a locale-sensitive manner. The servlet version of Duke's Bookstore uses the currency version of this method to format book prices.

JSTL applications use the fmt:formatDate and fmt:parseDate tags to handle localized dates, and fmt:formatNumber and fmt:parseNumber tags to handle localized numbers, including currency values. For more information on the JSTL formatting tags, see Formatting Tags. The JSTL version of Duke's bookstore uses the fmt:formatNumber tag to format book prices and the fmt:formatDate tag to format delivery dates.
