  ...
}

public class Applicant{
   ....
   private Customer c;
   public Cust         


        

Answer 1

Generics have what is known as type erasure - List and List are the same type, the compiler just places compile-time restrictions on what you can do with them.

You could check the type of the first object in the list and call a (differently-named) internal method based on that.
