Question
Create a guessing game called “Does It Have Legs?”, in which you think of an animal
and the computer tries to guess what it is. The game continually becomes “smarter”
as you play because you teach it how to become more specific with its questions.
For example, a typical game session might proceed as follows:
Computer: Does the animal you are thinking of have legs?
Player: Yes.
Computer: Is it a dog?
Player: Yes.
Computer: Yay! I win. Do you want to play again?
Player: Yes.
Computer: Does the animal you are thinking of have legs?
Player: Yes.
Computer: Is it a dog?
Player: No.
Computer: I give up. What was your animal?
Player: Horse.
Computer: Type a question for which the answer is Yes for Dog but No for Horse.
Player: Does it live in the house?
Computer: Do you want to play again?
Player: Yes.
Computer: Does the animal you are thinking of have legs?
Player: Yes.
Computer: Does it live in the house?
Player: No.
Computer: Is it a Horse?
Player: No.
Computer: I give up. What was your animal?
Player: Cow.
Computer: Type a question for which the answer is Yes for Horse but No for Cow.
Player: Do people ride it?
Computer: Do you want to play again?
Player: Yes.
Computer: Does the animal you are thinking of have legs?
Player: Yes.
Computer: Does it live in the house?
Player: No.
Computer: Do people ride it?
Player: No.
Computer: Is it a Cow?
Player: Yes.
Computer: Yay! I win. Do you want to play again?
Player: No.
(Hint: You might want to look up “binary trees” on the Internet as a method to
organize this application.)
Save the application as DoesItHaveLegs.java.
Explanation / Answer
As per given problem statement i have written the methods to guess the animal type by asking questions from the user. To Implement this we need to use the trees concept. Used the Binary Tree so that it can traverse the both the sides of the legs..see the below code ..
import java.util.*;
import java.io.*;
public void animalGame()
{
treeNoderoot=new treeNode("cat",0,0,0);
treeNode *current=root;
System.out.println("Let's play guess the animal.");
while(current!=0){
System.out.println("current.value");
if(answer())
current = current.leftChild;
else
current = current.rightChild;}
else {
System.out.println("I know. Is it a " + current.value + "?");
if(answer())
System.out.println("I won.");
else{
learnNewAnimal(current);
}
System.out.println("Try again?");
if(answer())
current = root;
else
return;}
}
}
public void animalGame()
{
treeNoderoot=new treeNode("snake",0,0,0);
treeNode *current=root;
System.out.println("Let's play guess the animal.");
while(current!=0){
System.out.println("Does it have leg");
if(answer())
current = current.rightChild;
else
current = current.leftChild;}
else {
System.out.println("I know. Is it a " + current.value + "?");
if(answer())
System.out.println("I won.");

learnNewAnimal(current);
}

return;}
}

if(answer())

System.out.println("Does it live underground?);

System.out.println("please answer yes or no. (Y/N)");
}

System.out.println("What is a Y/N question that I can use to tell a" + current.value + "from a " + newAnimal + "?");
string newQuestion;
treeNodenode1 = new treeNode(newAnimal, current, 0,0);
