The <c:if> tag has the 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

<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>
