<c: out> in JSTL

One of the general purpose core library tag is <c: out>. The main function of the this tag is to display the output to the user. It works like expression tag in jsp <%= ---%>.

Attributes of the <c: out> core action tag.

value: It specify the expression which needs to be evaluated.
default: We can use this attribute if the resulting value is null.
escapeXml: It checks whether there is any need to convert the &, <, > etc to their character encoding codes.

In this example we have used only one attribute i.e. value. It is a must attribute in the tag. We are just calculating the multiplication of two numbers by using the <c: out> core action tag.

The code of the example is given below:

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<html>
<head>
<title>Simple Calculation by using c: out</title>
</head>
<body bgcolor="#FFFFCC">
<h1>Simple Calculation by using c: out</h1>

<%-- Multiplying the numbers 2 * 3 dynamically --%>
2 * 3 = <c:out value="${2 * 3}" />

</body>
</html>

The output of the program is given below:
