This class is quite minimal. It contains the following: .An instance variable author of type String .An instance variable title of type String An instance variable year of type int (the publication year of that book); .A contructor Book(String author, String title, int year), which receives that new instance's author, title and publication year as paramters; .A method toString), which returns a String representation of that instance, using the format "author: title (yearl; .A method equals(Object o) We want our implementation to be as robust as possible. In particular, the method equals should handle every particular case you can think about. To help you with this, we have created the class TestBook.java: public class TestBook f public static void main(String] args) Book b1-new Book("D. Knuth", "TAOCP", 1978); Book b2new Book("D. Knuth", "TAOCP", 1971); Book b3new Book ("D. IAmNotKnuth", "TAOCP, 197e); Book b4new Book ("D. Knuth", "TAOCP v2", 1978); Book bs- new Book("D. Knuth", "TAOCP", 1978) 4:01 PM Type here to search 2/16/2019 Lab submissions-IT11121Agic ITI 1121 Laborary 5(2019) e HomelChegg.com Not secure l www.site.uottawa.ca/~JY/Courses/IT11121/lectures/labs/lab5-2019.html System.out.println(bi"equals"b2 + ":"+ b1.equals (b2)) System.out.println(bi "equals"b3":"b1.equals (b3)); System.out.println(bl" equals "b4 ":" b1.equals (b4)) System.out.println(b1" equals "b5b1.equals (b5) Book b6 new Book (nul1, "TAOCP", 1971); Book b7new Book("D.
