Doubt on Tags

[Padma priya Gururajan]

In Enthuware, it is mentioned that for looping over collections, a loop status object might be used in the tag body. How do we use the loop status object in the tag body?

Thanks in advance.

Which tags are you talking about ? JSTL's iteration tags ? (c:forEach, c:forTokens)

Hi,
I am talking about c:forEach tags.

Thanks in advance.

How do we use the loop status object in the tag body?

There is a varStatus attribute in the c:forEach tag. It's type is javax.servlet.jsp.jstl.core.LoopTagStatus. If you look at the LoopTagStatus API, you'll see that the following information is available : begin, count, current, end, index, step.
For example, the following will print the iteration count next to an album title :

<c:forEach var="album" items="albums" varStatus="status">
${status.count}.${album.title}<br>
</c:forEach>
