Question

<c:if test="${not empty userList)}">
    <table cellpadding="5">
        <tr class="even">
            <th>Name</th>
            <th>Gender</th>
            <th>Country</th>
            <th>About You</th>
        </tr>
        <c:forEach items="${userList}" var="user" varStatus="status">
            <tr class="<c:if test="${status.count % 2 == 0}">even</c:if>">
                <td>${user.name}</td>
                <td>${user.gender}</td>
                <td>${user.country}</td>
                <td>${user.aboutYou}</td>
            </tr>
        </c:forEach>
    </table>
</c:if>

When i remove <c:if test="${not empty userList)}"></c:if> it throws me error.
What does this condition check? My DB tables has users list, but yet this entire code is not displayed in my HTML itself.

Answer 1

that line is equivalent to

if(userList!=null && userList.size()>0)
