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_overview_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.
