<div dir="ltr" style="text-align: left;" trbidi="on">JSTL c:if tag is used as a conditional statement in JSP. It is similar like If statement in JAVA. Based on condition evaluation within test attribute, if tag decides to run the code within JSTL IF tag. </p>
<p> <b>JSTL <;c:if>; tag Example:</b></p>
<pre class="highlight" name="code"><;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">;
<;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>; </pre>
<pre class="highlight" name="code"><;html>;
 <;head>;
 <;meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">;
 <;title>;JSTL if tag Example<;/title>;
 <;/head>;
 <;body>;</pre>
<pre class="highlight" name="code"><;c:set var="salary" scope="session" value="${100000}"/>;
 <;c:if test="${salary>; 0}"/>;
 <;c:out value="${salary}"/>;
 <;/c:if>;
 <;/body>;
<;/html>;
</pre>
<p>
As you can see above, in the JSTL c:if tag, test attribute check the condition and if condition returns true, it executes the other statements within <;c:if>; and <;/c:if>; statement.</p>
