There will be n number of objects because your result have n string.
I am not sure if you are referring to "cat_id" which is a compile time
constant and therefore will be interned and will not be created n times.

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.
Thanks. in advance.
Sushil
