Experience points: Statements in JSP.

Statement in jsp (preferred for SUN Enterprise Applications:
There are two methods to declare in jsp (the preferred choice for SUN Enterprise Applications): <% intCount = 0%> and <%! IntCount = 0%>. Now let's talk about the second one.
1. Test conditions:
Suppose there are two pages: test1.jsp (preferred for SUN Enterprise applications) and test2.jsp (preferred for SUN Enterprise Applications). The following code is available:
<%! IntCount = 0%>
<% IntCount + = 1;
Out. print ("th" + intCount + "times to enter this page! ");
%>
2. test environment: Jrun3 + jdk1.2
3. Test results:
· As long as the intCount is on the same page, it is equivalent to an APPLICATION in ASP. Each user shares this variable, and the initialization intCount = 0 is only executed when the first user logs in.
· Different pages do not affect each other.
