Java HiLo遊戲 - 無法產生新的猜測

Question

SORRY我知道這個遊戲還有其他的帖子，但我的問題是具體的。我剛剛開始學習Java並將這款HiLo遊戲扔在一起，但我正在努力掙到2件東西 -

1）如果用戶想再玩一次，我如何獲得它來生成一個新選擇？ 2）如果用戶選擇中止遊戲，我沒有得到消息產生

幫助我可愛請，我是新的，容易受到Java！

package lab4; 

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

public class hilo 
{ 

    /** 
    * @param args 
    */ 
    public static void main(String[] args) { 
     // TODO Auto-generated method stub 

     //randomly pick a number between 1-100 
     Random rand = new Random(); 
     int pick = rand.nextInt(100) + 1; 
     int count = 0; 
     boolean play = true; 

     //prompt user to guess  
     Scanner scan = new Scanner(System.in); 
     System.out.println("*---------------------------------*"); 
     System.out.println("* Guess a number between 1-100: *"); 
     System.out.println("* (enter \"0\" to end at any time) *"); 
     System.out.println("*---------------------------------*"); 
     int guess = scan.nextInt(); 

     //on each guess, say if too low or too high 
     while (play = true) 
     { 
      while (guess != pick && guess !=0) 
      { 

       if (guess < pick) 
       { 
        count++; 
        System.out.println("Higher..."); 
        System.out.println(pick); 
        guess = scan.nextInt(); 
       } 

       else if (guess > pick) 
       { 
        count++; 
        System.out.println("Lower..."); 
        System.out.println(pick); 
        guess = scan.nextInt(); 
       } 

      } 


      if (guess == pick) 
      { 
       System.out.println("You got it! It only took you " + count + " guesses."); 
       System.out.println("Want to play again?"); 
       System.out.println("* Guess a number between 1-100: *"); 
       System.out.println("* (enter \"0\" to end at any time) *"); 
       guess = scan.nextInt(); 
       if (guess != 0) 
        play = true; 
       else 
        play = false; 
      } 
     } 

     if (play = false || guess == 0) 
     { 
      System.out.println("Bummer. See you next time!"); 
     } 

    } 
} 

Answer 1

兩個小東西，

int pick = rand.nextInt(100) + 1; 
// ... 

//on each guess, say if too low or too high 
while (play = true) 
{ 

一個=是分配，二是==平等。所以while (play == true)（這是詳細的）或while (play)。然後將pick移動到循環中。

// int pick = rand.nextInt(100) + 1; 
// ... 
while (play) { 
    int pick = rand.nextInt(100) + 1; 

而且應該解決這兩個問題。

Answer 2

你如果條件只是分配一個新值pick變量，你測試的guess平等和pick

if (guess == pick) 
{ 
    System.out.println("You got it! It only took you " + count + " guesses."); 
    System.out.println("Want to play again?"); 
    System.out.println("* Guess a number between 1-100: *"); 
    System.out.println("* (enter \"0\" to end at any time) *"); 
    guess = scan.nextInt(); 

    pick = rand.nextInt(100) + 1; // new value 

    if (guess != 0) 
    play = true; 
    else 
    play = false; 
}
