Internationalization tags are the second most used tags in JSTL. The most used tags are core tags, as you can refer to in my last post.
2022.09.17 - [JSP] - JSP) JSTL (JSP Standard Tag Library) - Core tags
Internationalization tags are related to numbers, dates, and timezone. The example tag with the URI is like this :
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>The prefix value is "fmt" and the URI ends with "fmt" which refers to the internationalization tag.
For your better understanding, let us look through some simple examples.
numberFormat Tag
<%@ page contentType = "text/html; charset=utf-8" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head><title>numberFormat Tag</title></head>
<body>
<c:set var="now" value="<%= new java.util.Date() %>" />
${now }<br>
<c:out value="${now }"/><br>
<fmt:formatDate value="${now}" type="date" dateStyle="full" /> <br> <!-- in detail -->
<fmt:formatDate value="${now}" type="date" dateStyle="short" /> <br> <!-- simple -->
<fmt:formatDate value="${now}" type="time" /> <br>
<fmt:formatDate value="${now}" type="both"
dateStyle="full" timeStyle="full" /> <br>
<fmt:formatDate value="${now}" pattern="z a h:mm" /> <br><br> <!-- z: timezone a: am/pm -->
<fmt:formatDate value="${now}" pattern="MM/dd/yy EEEE h:mm a z"/><br>
</body>

<fmt:formatNumber value="${price}" type="number" var="numberType" />
Number: ${numberType} <!-- Variable name -->
<br> KRW:
<fmt:formatNumber value="${price}" type="currency" currencySymbol="\\" />
<br> USD:
<fmt:formatNumber value="${price}" type="currency" currencySymbol="$" />
<br> Percentage:
<fmt:formatNumber value="${price}" type="percent" groupingUsed="true" />
<br> Percentage:
<fmt:formatNumber value="${price}" type="percent" groupingUsed="false" />
