The proper use of white space makes a major contribution to code readability.

This rule raises an issue when there is not a space character after the beginning and before the end of each comment (<!-- ... -->), directive (<%@ ... %>), and expression (<% ... %>).

Noncompliant Code Example

<!--Do the thing-->  <!-- Noncompliant; missing space at beginning and end of text-->
<%@page import="java.io.*,java.util.*" %> <!-- Noncompliant; missing space at beginning -->
<% String title = "My Page";%> <!-- Noncompliant; missing space at end -->

Compliant Solution

<!-- Do the thing -->
<%@ page import="java.io.*,java.util.*" %>
<% String title = "My Page"; %>
