I'm going to ignore other obvious problems and simply focus on the big picture 
here.  You idea how to accomplish this looks *TERRIBLE*.  Why aren't you using 
some kind of ORM?  At least use a light-weight library for translating data 
base entities into objects.

<http://commons.apache.org/dbutils/>

Also JPA will do some kinds of automatic instantiation for you:

<http://openjpa.apache.org/builds/1.0.4/apache-openjpa-1.0.4/docs/manual/jpa_ov
erview_mapping_inher.html>

I didn't check to see if those are the most recent docs (I don't use this sort 
of feature).  Google for "JPA table inheritance" and check through the results 
carefully.

Honestly, while we all appreciate the attempt, you example is far from 
complete.  We can guess at a few things, but you should think much more 
carefully at what the real problem is and design something to illustrate it.
