read up on JSTL, stop using Java code in JSP.

And read your code. You're iterating through the entire List, and only afterwards printing a single value.
Hardly surprising you're not getting the result you expect.

Scriptlets are bad because :

1-EL is more terse and readable.
2-scriptlets are not re-usable software components.
3-java and HTML should be separated as much as possible. Business logic does not belong in the presentation layer, and should be encapsulated in javabeans instead, which are re-usable.
4-scriptlets cannot use inheritance or composition
5-debugging scriptlets can be painful, if an exception is thrown halfway you might just get a blank page. So check the logs... Scriptlets are also a nightmare to maintain. I have "inherited" a project at my current workplace with more java code in JSPs than in .class files and its SPAGHETTI time. . . 
6-scriptlets are not unit-testable.
