The following JSF code contains two separate <c:if></c:if>. Let’s look at it.

<?xml version='1.0' encoding='UTF-8' ?>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:c="http://java.sun.com/jsp/jstl/core">
    <h:head>
        <title>JSF EL</title>
    </h:head>
    <h:body>
        <h:form>

            <c:set scope="request" var="row" property="x" value="10"/>

            <c:if test="#{row==10}">
                <h:outputLabel value="value = 10"/>
            </c:if>

            <c:if test="#{row==15}">
                <h:outputLabel value="value = 15"/>
            </c:if>

        </h:form>
    </h:body>
</html>

It simply displays value=10 on the JSF page at run time. I need to represent the above same <c:if></c:if> with the following if-elseif-else (Java context).

if(row.equals(10))
{
    //Do something...(JSF stuff)
}
else if(row.equals(15))
{
    //Do something...(JSF stuff)
}
else
{
    //Do something...(JSF stuff)
}

How can it be represented with Expression Language (EL) using JSF?

    The following code the easiest way:

     <h:outputLabel value="value = 10" rendered="#{row == 10}" /> 
 <h:outputLabel value="value = 15" rendered="#{row == 15}" /> 
 <h:outputLabel value="value xyz" rendered="#{row != 15 and row != 10}" />

    Link for EL expression syntax.
