Personally speaking i'd go in for the first approach because according to me
it would be more efficient if there are a lot of ResultSet Objects that
would have to be traversed in the while loop and i really don't find any use
of storing the String in a variable except for the fact that it makes your
code a little more cleaner and easier to follow.
Lastly, do remember that Strings are immutable objects in java.
Hope that helps :-).
Have a nice day.

Subject: Basic Object Reference Question
> Hi,
>
> I am having a basic object reference question. Consider the following
> code snippet:
> while (rootRs.next())
> {
>
> categories.addElement(getCategory(rootRs.getString("cat_id")));
> }
>
> Another code snippet:
> String catID = "";
> while (rootRs.next())
> {
> catID = rootRs.getString("cat_id");
> categories.addElement(getCategory(catID));
> }
>
> Now my question is which one is better? When we say
> categories.addElement(getCategory(rootRs.getString("cat_id")));
>
> then we are getting a reference to the resultset string object or its
> new object. If its a new String object, then the while loop will be
> creating n no of objects throughout the loop!!!

> Awaiting your feedback.
