我的隨機數猜謎游戲出現問題

Question

我的Java代碼需要幫助！

希望它循環播放所有內容，直到用戶輸入正確的數字為止。 當用戶輸入錯誤的數字時，應該說“輸入其他數字”。 當用戶輸入正確的數字時，應該說“恭喜您贏了”。 但是直到那之前，它會循環播放並說“輸入不同的數字”，經過5次嘗試后，我要說“您未能完成此任務！您想重試一次嗎？”

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

public class Projekt_1 {

    public static void main(String[] args) {
        String number;
        JOptionPane.showMessageDialog(null, "Welcome to the guessing game!" + "\nYou     gonna guess a number between 1 and 20." + "\nHOPE YOU LIKE IT!:)");

        Random amount = new Random();
        int guessnumber = anount.nextInt(20);
        int random;

        number = JOptionPane.showInputDialog("Guess a number between 1 and 20");
        random = Integer.parseInt(number);

        while (random == guessnumber){
            JOptionPane.showMessageDialog(null, "You won!" + "\nYour number was" + "" + guessnumber);      
        }

        if (random < guessnumber){
            number = JOptionPane.showInputDialog("Your number is to high :(" + "\nType in a new lower number!"); 
            random = Integer.parseInt(number);
        }else if (random > guessnumber){
            number = JOptionPane.showInputDialog("Your number is to low :(" + "\nType in a higher number!"); 
            random = Integer.parseInt(number);
        }
    }
}

Answer 1

那是因為您唯一的迭代語句僅顯示“ You won！.. etc”：

while (random == guessnumber){    
    JOptionPane.showMessageDialog(null, "You won!" + "\nYour number was" + "" + guessnumber);      
}

將其他代碼封裝在while循環下面，以將它們包含在while循環中。 如果您正確縮進代碼 ，則應該能夠發現自己的問題。 這是您要尋找的：

while (random != guessnumber){
    //prompt for user input
    if (random < guessnumber){
        //Show Message "Your number is too low...
    }
    else if (random > guessnumber){
        //Show Message "Your number is too high..."
    }
    else{    //got the number
        //Show Message "you won!.."
    }
}
