We don't immediately know and should not need to know the implementing Class for the interface. The Driver for the Database manages that for us and returns something that behaves like a ResultSet. We treat it like a ResultSet, and regardless of what exists behind the Interface should behave correctly.
You can always find the class using rs.getClass().getName() if you really need to know.

When you do that ... Looking at the class name, do you think it will be the same for Oracle, UDB, MySQL and every other database?
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
