finalizors and weak references

["Alexandra Barros" <alexandra.barros@...>]

Hello,

I'm doing some research for my Master thesis. I would like to get some
information about the use of finalizers and weak references. If you
have only 1 minute free, please answer these questions:

1. Have you ever used finalizers?
2. If yes, what for and in which programming language?

3. Do you know weak references?
4. If yes, have you ever used it?
5. If yes, what for and in which programming language?

Thank you in advance,
Alexandra Barros.
