Generate dynamic variables

Question

I'm kinda new to JSP, and have the following question:
is it possible to generate dynamic variables in JSP? I searched the WWW, and it seems nobody ever used it. Or I just searched wrong :)
So:
String result = "";
for(int i = 1; i <= 10; i++){
result = "test" + i;
// do something with result here
I would like that the string "result" becomes a variable: test1, test2, test3, ...
I know it is possible in PHP like this:
for($i=1; $i<=$10; $i++){
$result = ${"test".$i};
// here I can do something with the generated variables $test1, $test2, $test3, ...
Does anyone got a solution for this problem? Cause it's driving me crazy ;)
