Thank you all, i am very glad to see all these discussions.
is one source.
Object Reuse section, says
objects are expensive to create. Where it is reasonable to reuse the same object, you should do so.
and there is alot of sources that says the same thing. :P
I understand the reason why this happens, and I know how to solve it, but as I told you How to get benefit of object reusing.
Another points are welcome also, even if I know these points, it is good to refresh them.
