NEED TO BUILD IN JAVA AND RUN PLEASE

Code in bold comment needs to be finished. Just need help finishing the code

The code is for a Tree guessing game

//package trees;

import java.util.Scanner;

class AnimalNode {

public String text; public AnimalNode rightPtr; public AnimalNode leftPtr;

public AnimalNode (String s) { text = s; }

public String toString() { return text; } }

class TreeGuessingGame {

public AnimalNode root;

public TreeGuessingGame() { root = new AnimalNode("Does it have 4 legs?"); root.leftPtr = new AnimalNode("dog"); root.rightPtr = new AnimalNode("chicken"); }

public void play() {

Scanner keyboard = new Scanner(System.in); System.out.println("Think of an animal and I will"); System.out.println("try and guess it");

AnimalNode current = root; AnimalNode parent; boolean isLeftChild = true; String answer; while(current.leftPtr != null) { //while not a leaf parent = current; System.out.println(current.text); answer = keyboard.nextLine(); if(answer.equalsIgnoreCase("yes")) { current = current.leftPtr; isLeftChild = true; } else { current = current.rightPtr; isLeftChild = false; } } System.out.print("Is the animal you're thinking of a "); System.out.println(current.text + "?"); answer = keyboard.nextLine(); if(answer.equalsIgnoreCase("yes")) System.out.println("I won, I guessed it!!"); else { System.out.println("You won"); //1 ask the user to enter in their animal //2 Make a new Node with this animal //3 ask the user to enter in a "yes" question // about their animal //4 Make a new Node with this question //5 set New Question Node leftPtr to point to // the new Animal Node //6 set New Question Node rightPtr to point to // the old Animal Node that was just guessed //7 set the parent's left or right node pointer // (depending if the left or right path was taken) // set that parent's ptr to point to the new // question node } }

public static void main(String[] args) {

TreeGuessingGame game = new TreeGuessingGame(); game.play(); }

}
