Question

这是我为课程创建的一个小游戏 - 工作正常除了如果猜测==数字，消息框没有显示，程序跳过它并转到下一个关于总猜测的消息等等...我的逻辑错了，但我很困惑。我觉得我已经尝试了一百万件事......任何帮助都会非常感激。

import java.util.Random; 
import javax.swing.JOptionPane;

public class GuessingGameTestMyIdeas {

    public static void main(String[] args) {
        Random rand = new Random(); 
        int number = rand.nextInt(32)+1; 

         int guessCount = 0; // total count variable
         int lessCount = 0; //  number of less than guesses
         int moreCount = 0; //  number of greater than guesses

         String guessString = JOptionPane.showInputDialog("Guess the number I'm thinking of, between 1 and 32: ");
         int guess = Integer.parseInt(guessString) ;  

         while (guess != number){  //run this loop while guess is not equal to the random number generated.
             if (guess == number){
                JOptionPane.showMessageDialog(null, "You guessed correctly");
             } else if (guess < number){
                 lessCount = lessCount + 1;
                 String lowString = JOptionPane.showInputDialog("Your guess is too low. Next Guess:");
                 guess = Integer.parseInt(lowString); 
             } else { 
                 moreCount = moreCount +1;
                 String highString = JOptionPane.showInputDialog("Your guess is too high. Next Guess:");
                 guess = Integer.parseInt(highString);

             }
             guessCount += 1; // after each guess, the guessCount goes up by one
         }    

         String output = "Your total number of guesses is " + guessCount + " with " + lessCount + " smaller guesses " + moreCount + " larger guesses.";
         JOptionPane.showMessageDialog(null, output);

Answer 1

你必须移动

行

JOptionPane.showMessageDialog(null, "You guessed correctly");

在while循环后面。

或者在while循环的末尾移动if，但第一个选项对我来说似乎更清楚。

你循环的条件是guess != number，并且在你要求guess == number之后。因此，这永远不会成真。当玩家猜对了，循环就会离开，而if claus也不会被再次评估。

顺便说一句：调试你的程序会向你展示。

Answer 2

循环时将线条放在外面。

if (guess == number){
        JOptionPane.showMessageDialog(null, "You guessed correctly");
}

我希望它有所帮助!!

如果分支在循环中跳过内部
