使用最少猜测的猜测游戏在 Java 中不起作用

Question

我正在使用 NetBeans 用 Ja​​va 创建一个猜谜游戏。猜谜游戏允许用户猜一个 1 到 10 之间的数字。每一轮他们有 5 次猜数字的机会。比赛共有三轮。用户完成游戏后，输出统计信息，包括最小猜测次数和最大猜测次数。

最小猜测不起作用，它总是输出 1。现在，我已经设置了程序，以便跟踪用户每轮猜测的次数。在每一轮之后，它将这个值与最小值和最大值进行比较。 minGuess 设置为 5，因为猜测次数不能超过 5 次。 maxGuess 设置为 1，因为他们总是会猜测一次或多次。

static void numberGuess(int guess, int randNum) {                              //creating a method to check if the user has guessed the correct number or if the guess should be higher or lower

if (guess < 0 | guess > 10) {
    System.out.println("Please enter a valid number between 1 and 10."); 
}
else if (guess == randNum) {
    System.out.println("You guessed the number correctly");
}
else if (guess < randNum) {
    System.out.println("Guess is too low");
}
else if (guess > randNum) {
    System.out.println("Guess is too high");
}




}

Answer 1

y 从一开始，并且从不小于一，因此 minGuess 始终为一。

   for (int y = 1; y <= 5; y= y + 1) {             
   ...
       if (y < minGuess)                    
           minGuess = y; 
   ...
   }

考虑只在猜测成功后更新 minGuess 和 maxGuess。

Answer 2

你的 if 语句放错地方了。

您每次都在询问。如果用户没有猜对数字。

所以把它放在你的 numberguess 方法中：

else if (guess == randNum) {
 System.out.println("You guessed the number correctly");
 if (y < minGuess)                    //compares to see if the minimum number of guesses is less that the number of guesses the user has made this round
   minGuess = y; 
 if (y > maxGuess)                    //compares to see if the maximum number of guesses is greater than the number of guesses that the user has made this round 
   maxGuess = y; 
 }
