I didn't originate the question, but I can give you a
couple of reasons why.
1. I can speculate that creation of a new object is more expensive
than just clearing an existing one
2. The way I wrote a couple of servlets was I created a template
class responsible for creation of general page look and feel. So a servlet
would pass several dynamically generated elements to that template
page which had to be removed after output was done so the template
is ready to be reused.
Not sure if these examples are convinsing. Also, I was able to live without
clearElements() so far.
