與我的隨機數猜遊戲存在問題

Question

我需要我的java代碼幫助！

要循環投擲一切，直到用戶輸入正確的數字。當用戶輸入錯誤的號碼時，應該說「輸入不同的號碼」。當用戶輸入正確的數字時，應該說「恭喜你贏了」。 但在那之前它會循環並說「輸入不同的數字」，並且在5次嘗試之後，我想讓它說「你沒有完成這項任務！你想再試一次嗎？」

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

那是因爲你只迭代語句只顯示「你贏了。等等！」：

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

附上您的while循環下面的其他代碼，包括他們的內while循環。如果您的正確地縮進您的代碼，您應該能夠發現自己的問題。這是你在找什麼：

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!.." 
    } 
}
