Question

我正在尝试制作一个高低数字猜谜游戏，如果他们的猜测太高，太低或太准确，就会向用户报告。除了成功猜测（所有事情）之外，一切都按预期工作。输入正确的数字后，循环打印＆＃34;您的猜测是正确的＆＃34;声明以及尝试次数。这就是我想要的。但是，不是询问用户是否想要重播下一个，而是返回“太高”＆＃34;响应。我是否错误地嵌套了这个？

import java.util.Scanner;
import java.util.Random;
public class hilo2 {



    public static void main(String[] args) {

    int guess = 0;
    int attempts;
    String quit;
    boolean replay = true;

    Scanner scan = new Scanner(System.in);

    Random generator = new Random();


    while (replay) {
            attempts = 0;
            int answer = generator.nextInt(101) + 1;
            System.out.println(answer);//for testing
            System.out.println("Guess a number between 1 and 100. Enter your     guess (0 to quit): ");
            guess = scan.nextInt();
            scan.nextLine();

            while (guess != 0){


            if (guess < answer) {
                System.out.println("You guess was too low. Guess again (0 to quit): ");
                guess = scan.nextInt();
                scan.nextLine();
                attempts++;
            }
            else if (guess > answer) {
                System.out.println("Your guess was too high. Guess again (0 to quit): ");
                guess = scan.nextInt();
                scan.nextLine();
                attempts++;
            }

            else {
                System.out.println("Your guess was correct!");
                attempts++;
                System.out.println("Number of guesses: " + attempts);
                answer = 0;
            }

        }
        System.out.println("Would you like to play again? (y/n): ");
        String input = scan.nextLine();
        if (input.equalsIgnoreCase("n")) {
            replay = false;
        }
    }
}

}

Answer 1

你有

 while (guess != 0){

更改代码以打破循环

else {
            System.out.println("Your guess was correct!");
            attempts++;
            System.out.println("Number of guesses: " + attempts);
            answer = 0;
            break; // add this or change above line to guess = 0;
 }

Answer 2

while (guess != 0) {
    if (guess < answer) {
        System.out.println("You guess was too low. Guess again (0 to quit): ");
        guess = scan.nextInt();
        scan.nextLine();
        attempts++;
    } else if (guess > answer) {
        System.out.println("Your guess was too high. Guess again (0 to quit): ");
        guess = scan.nextInt();
        scan.nextLine();
        attempts++;
    } else {
        System.out.println("Your guess was correct!");
        attempts++;
        System.out.println("Number of guesses: " + attempts);
        answer = 0;
    }
}

你没有把它嵌套错误，但你没有条件中止while循环。

您将answer设置为0，然后返回到while循环的开头。发现猜测现在太高了，因为答案是0。

我想你想做guess = 0;。或者你也可以在那里放break;。

循环返回不正确的响应
