HFS Doubt

[Ramesh NarayananPerumal]

Hi,
I am new for JavaRanch and preparing SCWCD.Pl clarify my doubts.
In Page 293:
<! int doubleCount(){
count = count*2;
return count %>
<! int count=1; %>

It is ok because java accepts forward referncing.

but in case of scriplet in page 300
<% int y = 5 + x; %>
<% int x = 2; %>
They mentioned this won't complie. Why it will not compile?

Declaration of new variables into <%! %> will define the variable as class members. So you can refer to "count" into the "doubleCount" function.

However, declarations of new variable into scriplets (<% %> will define+ the variable locally. So you cannot reference x, as long as it has not been declared.
