I have an abstract class "title" and 2 classes that inherit from it: book and magazine. I would like to have a single db with a single id per book or magazine, (I think it's easier). So I created a "title" db with an enum for the 2 classes, but now I'm unsure how to implement that in java... I created an enum in title but I can't instantiate title since it's abstract... I'm kinda new to Java and programming. Thank you to those that will help.
