20 question Game involving recursive methods

I have a problem with compiling my program. Any help please.

My code of line where it says "Node first = question.new Node()" i get the error"String.Node cannot be resolved to a type"

import java.util.Scanner;

//import TwentyQuestions.Node;

public class TwentyQuestions { class Node {

    public String question;
    public Node yesChild;
    public String name;
    public Node noChild;
    public void branch() {
        Scanner in = new Scanner(System.in);
        String input;
        if(question != null)            // Keep traversing branches.
        {
            System.out.println(question);   // Ask question.
            input = in.nextLine().trim().toLowerCase();
            if (input.contains("yes"))
                yesChild.branch();      // Yes branch.
            else
                noChild.branch();       // No branch.
        }
        else if(question == null)           // Reached end of branch.
        {
            System.out.println("Is it a/an " + name + "?"); //Guess animal.
            input = in.nextLine().trim().toLowerCase();
            if(input.contains("yes"))   // Animal found. Return to base.
            {
                System.out.println("All your base are belong to us.");
            }
            else                // Guess is incorrect, add new animal.
            {
                System.out.println("I give up.");
                System.out.println("What is your animal?");
                String newName = in.nextLine().trim().toLowerCase();
                System.out.println("What is a question that you "
                        + "would answer no to " + newName + ", but "
                        + "yes to " + name + "?");
                String newQuestion = in.nextLine().trim();
                yesChild = new Node();
                yesChild.name = name;
                noChild = new Node();
                noChild.name = newName;
                name = null;
                question = newQuestion;
                System.out.println("Your animal, " + newName 
                        + ", has been added to my databanks.");
            }
        }
    }
        // TODO Auto-generated method stub

    }
