Common JSTL FMT (format formatted) label usage Collation _jsp programming in JSP

The JSTL tag provides support for internationalization (i18n), which can display different languages depending on the client domain that makes the request. It also provides a way to format data and dates. Implementing these features requires the I18N Format Tag library (i18n-capable formation tags liberary). The method for introducing the tag library is:
<%@ taglib prefix= "FMT" uri= "Http://java.sun.com/jsp/jstl/fmt"%>
The I18N Format Tag library provides 11 tags, which can be functionally divided into 3 categories as follows:
(1) Date format of the number. FormatNumber tags, formatdata tags, parsenumber tags, parsedate tags, timezone tags, settimezone tags.
(2) Read the message resource. Bundle label, message label, Setbundle label.
(3) Internationalization. SetLocale label, requestencoding label.
The features and usage of these tags will be described in detail.
