Which of the following statements are correct regarding the forEach tag of JSTL?

The EL code within the body of the tag may refer to the iteration variable but scripting code cannot.

For example, <%=dept.getName()%> is invalid here:

<c:forEach var="dept" items="${departments}">
  <c:out value="${dept.name}"/><br><%=dept.getName()%>
</c:forEach>

<% Employee emp = new Employee();
emp.setEmail("abc@gmail.com");
java.util.List<Employee> empList = new java.util.ArrayList();
empList.add(emp);
request.setAttribute("empList", empList); %>

<c:forEach var="emp" items="${empList}" varStatus="status">
Emp email: <%=emp.getEmail()%> <br>
</c:forEach>

Emp email: abc@gmail.com

One of the option which is given as true is:

The EL code within the body of the tag may refer to the iteration variable but scripting code cannot.

The explanation is given as below in answer:

Code: Select all

For example, <%=dept.getName()%> is invalid here:

<c:forEach var="dept" items="${departments}">
  <c:out value="${dept.name}"/><br><%=dept.getName()%>
</c:forEach>

I tried following in JSP:

<% Employee emp = new Employee();
emp.setEmail("abc@gmail.com");
java.util.List<Employee> empList = new java.util.ArrayList();
empList.add(emp);
request.setAttribute("empList", empList); %>

<c:forEach var="emp" items="${empList}" varStatus="status">
Emp email: <%=emp.getEmail()%> <br>
</c:forEach>

I got the output as

Emp email: abc@gmail.com

.

Please correct if am wrong.

Thanks,
