I have some questions regarding design pattern (DP) usage, in particular for Java developers.
i) Which DPs have you used, as far as you can remember, and how often?
ii) How much have they helped your development work?
iii) If you work in a project group, are there group standards for architectural and design pattern usage?
iv) How can patterns be used more beneficially?
v) Did you (or your group) get design pattern training?
Thanks for your contribution.
