Experience points on the declaration in the JSP

Declaration in JSP:

There are two ways to declare in a JSP: one is <% intcount=0%>, and the other is <%! Intcount=0%>, now talk about the second kind.

1, test conditions:

Suppose there are two pages test1.jsp and test2.jsp have the following code:

<%! Intcount=0%>

<%intCount+=1;

Out.print ("The" +intcount+ "the number of people entering this page!");

%>

2. Test environment: jrun3+jdk1.2

3, test results:

• This intcount as long as it is on the same page, is equivalent to an ASP in a application, each user share this variable, and initialization intcount=0 only when the first user log in execution.

• But different pages do not affect each other.
