How to perform an action in a jsp file?

Question

Java

Using spring mvc, I send an object of type int or long, but how in jsp in this code to subtract it, add it, etc...

<c:forEach items="${int}" var="int">
               ${int.a}-${int.b}
</c:forEach>

Answer 1

If I understand correctly, then

<c:forEach items="${int}" var="int">
           <c:set var="Amount" value="${int.a+int.b}" />
 <c:set var="difference" value="${int.a-int.b}" />
</c:forEach>
