for loop to jstl forEach

Question

How to convert below for loop to a jstl foreach:

for(int i = 0 ; i<=21; i+=3){
  // print foo
}

This is what I have so far:

<c:forEach varStatus="loop" begin="0" end="21">
  // display foo
</c:forEach>

Answer 1

Acoording to jstl you should try:

<c:forEach begin="0" end="21" step="3" varStatus="loop">
    <c:out value="${loop.count}"/>
</c:forEach>
