java

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
  <c:set var="myVar" value="<c:out var="myVar" />" />
</c:forEach>

I want to concatenate the values of currentItem.myVar and output it at the end of the loop, problem is I can't figure out how to do this...

(Preferably not using Java)
