Write Book.java program
The Book constructor will be used to initialize all attributes of the Book object. The initial status of the book should be AVAILABLE, and the patron and due date should be null.
Like the constructor, the checkin method should set the book's status to AVAILABLE and assign null to both patron and due date.
The checkout method should make the book UNAVAILABLE and save the given patron and due date in the object.
The equals method checks whether two books have the same isbn. If the given object is a Book, compare this.isbn with the other book's isbn. If the given object is a String, compare this.isbn with the string.
In the UML diagram, getX is actually eight methods: one accessor method for each of the eight attributes. These should be easy to implement (Eclipse will generate them automatically). Note that the class should have no "setX" methods.
The toString method should return a String representation of the book. If a book is initialized with the following parameters ("aaa", "bbb", "1234BBBBBBBBB", 2013, 10), it should return a String exactly as follows: "Title: aaa, Author: bbb, ISBN: 1234BBBBBBBBB, Year: 2013, Pages: 10."
