No, for most discussion we prefer to use the public boards. There are some specific things that we find it's better to discuss privately, but basic java questions are not among them. In general we wnat to share knowledge, not hide it.

I recommend you check out Overriding vs Hiding for more info on the difference between overriding and "redefinition" (which is also called hiding).
