Search keys with duplicates were addressed by adding a property. How will this affect the B+ tree's height?

What is the easiest way to fix a Node Constructor in my Java program? The current problem is it does not accept the Object being passed into it.

In Java for the RedBlackTree how would you make the InsertFixup and RemoveFixup with the following RedBlackTree and BInNode class...   public class BinNode{private String data;private BinNode left;private BinNode right;private int height; //height field as with AVL tree or Red Black Treeprivate boolean color; //Needed for Red Black Treepublic BinNode(){data = "";left = null;right = null;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}public BinNode(String d){data = d;left = null;right = null;}public void setData(String d){this.data = d;}public String getData(){return this.data;}public void setLeft(BinNode l){this.left = l;}public BinNode getLeft(){return this.left;}public void setRight(BinNode r){this.right = r;}public BinNode getRight(){return this.right;}}   public class RedBlackTree {private BinNode root;private BinNode nil;public RedBlackTree() {nil = new BinNode();nil.setColor(false); // Black color for NIL nodesroot = nil;}public…

There is no arrayTree or testTreeADT description!!!!! 1. Problem DescriptionYou are to develop a program that plays the perfect game of TicTacToe. It should never lose. Yourproject can be done in three steps of increasing complexity. Develop the Tree ADT as an array-based concreteimplementation. For the program, there is no code to start with; you are to develop everything. However, the UMLdesign and test drivers for the Tree ADT have been supplied so you can test your implementation. You canreview the sample output below to get an idea of the interaction. Create the Array-based Tree ADT. Run it with TestTreeADT.java to insure it works.
