HOw to access a variable in another scriptlet ?

Question

I declare a integer variable and want to access it in another sciptlet in the same page.That scriplet is to display a value in a table.
The table is in a top level loop.I want to update the same variable in inner loop so that when I again go to the top level loop I should be able to get the updated value.

Think of scriptlets as small sections of code within the same method. The entire JSP is one method, and your scriptlets are executed within that method just like it normally would. All HTML gets basically broken down into out.println(String) calls wrapped around any scriptlet calls. So if you had this
bunch of HTML
<% int bob; %>
bunch of HTML
<%for(; bob < 10; bob++)
%>
bunch of HTML
<%
%>That gets translated into
out.println("bunch of HTML");
int bob ;
out.println("bunch of HTML");
for(;bob < 10; bob++ )
    out.println("bunch of HTML");
}
