Question

我在java中创建了一个猜谜游戏。它非常简单：计算机选择一个随机数，用户可以选择是否需要5,10或20个机会来猜测这个数字。在每次猜测之后，程序将告诉他们他们的猜测是高于还是低于幻数。如果他们猜出这个数字，他们会收到一条祝贺信息，然后他们会问他们是否想再次参加比赛。如果他们没有猜到这个号码，他们也会收到一条消息，并询问他们是否想再玩一次。有一件事我想添加到我的代码中，我似乎无法弄明白...... 当用户猜出幻数时我想在祝贺信息之后做这样的事情：

恭喜，鲍勃！你猜到了6个猜测中的神奇数字。

你没有使用这些猜测：

7

8

9

10

我尝试了这个，我很快意识到没有任何意义，但是从这里开始我就被卡住了。

System.out.println("You did not use these guesses: "+ (i-numberOfGuesses));

我应该怎么做呢？我宁愿不使用数组。

import java.util.Random;
import java.util.Scanner;

public class NewClass 
{
  public static void main(String [] args)  
  {
     final String SENTINEL = "no"; 
     int guess;
     String playAgain;
     int numberOfGuesses;

      Scanner scan = new Scanner( System.in );


      System.out.print( " Enter your name: ");
      String name = scan.next();


      System.out.print(" Would you like to try to guess a number? (Yes or No):");
      String answer = scan.next();

      while(!answer.equals(SENTINEL)){

        if (answer.equals("yes"))
        System.out.print("How many guesses would you like? (5, 10, 20): ");
            do {
            numberOfGuesses = scan.nextInt();

            if (numberOfGuesses == 5 || numberOfGuesses == 10 || numberOfGuesses == 20 )
                break;
            System.out.print("How many guesses would you like? (5,10,20): ");
            } while (true);

            Random random = new Random();

            int randomNumber = random.nextInt(100) + 1;


           {
          for(int i = 1; i <= numberOfGuesses ; i++){
   System.out.print("Enter guess #"+i+": ");
   guess = scan.nextInt();

   if (guess > randomNumber && guess <= 100)
      System.out.println("Your guess, "+guess+", is greater than the magic number.");

   else if (guess < randomNumber && guess > 0)
      System.out.println("Your guess, "+guess+", is less than the magic number.");

   else if (guess == randomNumber){
      System.out.println("Congratulations, "+name+"! You guessed the magic "
              + "number in "+i+" guesses.");
      System.out.println("You did not use these guesses: "+ (i-numberOfGuesses));
      break;
 }
   else 
       i--;

   if (i == numberOfGuesses)
        System.out.println("Sorry, " + name+", you did not guess the magic "
                + "number, " + randomNumber + ", in "+ numberOfGuesses + " tries.");

          }

         System.out.print("Would you like to try to guess a number? (Yes or No):");
     answer = scan.next();
} 

            }}}

我认为你应该用这个循环替换你提出的（但是不正确的）代码行：

    if (i != numberOfGuesses) {
      System.out.println("You did not use these guesses: ");
      for (int j = i + 1; j <= numberOfGuesses; j++) {
        System.out.println(j);
      }
    }

另外，你有一个错误：如果你在开头回答是，一切都很好，你玩游戏。但是如果您回答是（如问题中所提出的）或任何其他文本，它会等待另一个输入，当您输入内容并按回车键时，它会继续游戏。因此，如果您输入＆＃34;否＆＃34;，请按Enter键，输入1，按Enter键仍然会播放。

在猜谜游戏（java）中打印连续数字？
