Java – 比较字符串输入

import java.util.Scanner;

public class TrueFalseQuiz {

    public static void main(String[] args) {
        Scanner myScanner = new Scanner(System.in);
        String youranswer;

        boolean answer = false;
        System.out.print("The queens name is Elizabeth? yes or no ");
        youranswer = myScanner.toString();

        String start = myScanner.next();

        {
            if (youranswer.equals("yes")) {
                answer = true;
            }
        }

        if (answer == true) {
            System.out.println("Answer is correct");
        } else {
            System.out.println("Answer is wrong");
        }
    }
}

此代码似乎没有将输入与我想要的字符串(“是”或“否”)进行比较.我是初学者,这只是我正在玩的基本代码.
