Explanation / Answer

Suppose we want to model several different physical bookshelves full of books.
Which of the following would represent the best structure in Java?

Answer: B

A Book class, where each book is an object, and a HashSet of Book objects, where each Set represents a bookshelf

Reason :

Because suppose a Book is a class in this you can take each book in the class as a object and if you
use HashSet you can store the books from objects and so each hash set represnts a bookshelf..
