I'm trying to create a basic
Java program that models a public library (w/ three classes: Library, Shelf, & Book). The library should be aware of a number of shelves. Each shelf should know what books it contains. Make the book object have "enshelf" and "unshelf" methods that control what shelf the book is sitting on. The library should have a method to report all books it contains. I've been stuck on this for hours I need help please thanks a lot. I'm not sure how these classes should connect or understand each other.
