$1.$ Consider the Book class that you wrote in Worksheet $4.$ Here, you are asked to implement the BookNode class which will hold Book objects. The BookNode class has the following members:

$$ A private instance variable data of type Book

$$ A private instance variable link of type BookNode

$$ A constructor which takes two parameters of type Book and BookNode to initialize the private instance variables.

$$ Public getter and setter methods for each private instance variable

$$

Create a driver class named BookNodeDriver.

Inside the main$()$ method inside the driver class, declare two Book objects named myBook yourBook with the following characteristics:

myBook: title $=$How to Catch a Dinosaur$,$ year$=2019,$ isNew$=$true

yourBook: title $=$I am Enough$,$ year $=2018,$ isNew$=$false

$$

Inside the main$()$ method inside the driver class, declare two objects of type BookNode named nodeA and nodeB with the following characteristics:

nodeA: data $=$ myBook, link $=$ null

nodeB: data $=$ yourBook, link $=$ null

$$

Add two additional BookNode objects of your choice
