How to avoid Java code in JSP files

Question

I'm new to Java and I know that something like the following three lines

<%= x+1 %>
<%= request.getParameter("name") %>
<%! counter++; %>

In JSP version 2 there exists a method to avoid Java code in JSP files. Can someone please tell me the alternative JSP 2 lines, and what this technique is called?

Hello @kartik,

JSTL offers tags for conditionals, loops, sets, gets, etc. For example:

<c:if test="${someAttribute == 'something'}">
   ...
</c:if>

JSTL works with request attributes - they are most often set in the request by a Servlet, which forwards to the JSP.

Hope it helps!!
Thank You!!
