# JSTL Core <c:if> Tag

The <c:if> tag evaluates an expression and displays its body content only if the expression evaluates to true.

## Attribute:

The <c:if> tag has following attributes:

Attribute | Description | Required | Default
--- | --- | --- | ---
test | Condition to evaluate | Yes | None
var | Name of the variable to store the condition's result | No | None
scope | Scope of the variable to store the condition's result | No | page

## Example:

    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
    <html>
    <head>
    <title><c:if> Tag Example</title>
    </head>
    <body>
    <c:set var="salary" scope="session" value="${2000*2}"/>
    <c:if test="${salary > 2000}">
       <p>My salary is: <c:out value="${salary}"/><p>
    </c:if>
    </body>
    </html>

This would produce following result:

    My salary is: 4000
