LAB EXERCISE 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 (doc-index.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. For this question, you are required to submit Java files such as Book, BookStore, BookStore Owner, SortBooksby Year in your Eclipse project. eclipse-workspace - EE SUO LABIW20_stud/s/boo Shore BookStore V8 - Eclipse IDE File Edit Source Relector Navigate Search Project Run Window Help Quick Access o book store that has an - YOU NEE D HER TO HOLD THE Tek or HS Tank Store > private Treepok, Tatever boks; private Tonkatarebumer owner; buire > Book, ava > BankStorej > T BookStorcowner, ava > Sorteoksby Year.js > Texturvajave Toitializes this book store so that it has the specified owner and no par uner the owner of this book store puble BookstoreBookStorer wer) { > > > I > > Flightinnjava Fight Managersystemjava Alreadystocephoin.js ndespion.java Passengerinto, ava Teeser.
