Java classes representing DB tables

[aa74]

I want to create java classes that represent some tables in my database, my question is how to deal with foriegn keys?
how can I refenrence them to their origanal tables?

say I have the following tables

student(StudId,fname,lname)
unit(UnitCode,name)
register(StudId,UnitCode)
assignment(Id,name,UnitCode)

Thank you

I found a Table class already prebuilt in the Libraries, I can find it for you but the thing to do is just type Java Table Class in Google and you will find plenty for what your sample code shows.
