Complete the implementations of various classes in a bookStore. Read the API for bookStore carefully, the API of this lab is available under doc folder in the Java project folder (docindex.html). Some example tests are given to you in the Testerv3 class. We consider a database that stores information about books and owners. Each book has (e.g., String title, int price, int yearPublished), whereas BookStoreOwner has (String name and long id). You must implement all methods in the BookStore.
