A bookshop would like to implement its catalog of books as a binary search tree, called BookBST 1. Write a Book node class, called BookNode, to hold the following information about a Book: isbn (as int) . price (as int) Book Node should have constructors and methods igetters, setters, and toString) to manage the above information as well as the link to left and right children. 2. Write the BookBST class, which is a binary search tree to hold objects of the class BcokNode. The key in each node is the isbn. This class should define: . An instance variables root. The BookBST dass should implement the following interface MyBST import java . ut.il.hrrayList; public interface MyBST public boolean isEmpty) // return xue if the ree is empty. talse otherwise public int treeSize (BookNode sn) recuraly methad that retuatho umber of nodes in the tree public void addBook (BookNode sn) // &dds a Book at; the ron-af tne iist public ArrayList preorderTraversal) //preorder traversa. oy raturning an rraylist of visited Book public ArrayList inorderTraversal0 inarder traveral by reuing an azray o visited Book publie ArrayLiat BookNode> postordertraversalo //pastorder travarsal by raturning an array of visited Hook nodea publie BookNode findMin (BookNode sn) recursive rethod that returns the reterence to the Book node. which has the amalleat isbn in the BST public BookNode EindMax non-Teauraiva method hat roturra th roferanon to the Book node, which has the hghest isbn in the BST public BookNode search(int isbn) f a non-recureive method that searches and returna the public int priceGreaterThan (int p) // method that returns the number of BookNode objects having traversal algori thma) public int numberofLeaves (BookNode sn) cursive method that roturhnunber of leaf nodas in the binary #sazch trea 3. Write a TestBookBST class to test the above classes. This class should have a main method in which you perform the folowing actions: a) Create a BockBST object, Insert 50 BookNode objects (using a tor loop) into the created BST in the tollowing way b) isbn is a random number between O and 1000 price is a random number between O and 300. c) Call the preorder traversal method and print out its resulting arraylist of nodes, d) Call the preorder traversal method and print out its resulting arraylist of nodes, e) Call the inorder traversal method and print out its resuting arraylist of nodes, t) Print out in the number of Books that have a price greater than 150. g) Print out the number of leaf nodes in the binary search tree, h) Print out the details about the Books node with the smalest isbn, Print out the details about the Books node with the highest isbn. For each operation above, print a smal message that describes the operation you are doing. For example: System.out-println Inaertien of 140 Books in the binary search tree") A bookshop would like to implement its catalog of books as a binary search tree, called BookBST 1.
