As another reply indicated, there is no reason to create a NEW string.
Strings are immutable objects. This means, you can NOT change any part of a
String without a NEW string being created for you automatically. Therefore,
its faster and less resources used to just point a reference variable to the
String returned from the request:
String s = request.getParameter("attribute-name");
The s variable now points to the SAME memory location the request object
uses to point to it.
There is really only one reason I can think of ever using new
String(string-source); That is if you want the NEW string to be modified in
some manner without changing the source string passed in. Even so..because
they are immutable, anytime you do anything on a String, a new String is
created.
