You can't exactly return multiple values from a method in Java, but you can always return a container object that holds several values. In your case, the easiest thing to do would be to return the ResultSet, Customer.

If you're concerned about exposing your data layer to your UI, you can copy the data from the ResultSet into a structure that is less specific to the database, either a List of Maps, or perhaps a List of Customer objects, where Custom is a new class that represents your business entity.
