在 HiLo 猜谜游戏结束时产生新随机数的问题

Question

我正在 Java 创建一个 HiLo 猜谜游戏。到目前为止，我所拥有的一切都按预期工作，除了最后提示用户再次玩游戏时，随机数与上一个游戏相同。当用户选择玩新游戏时，如何让代码产生一个新的随机数？

    int answer  = (int)(Math.random() * 100 + 1);
    int guess = 0;
    int guessCount = 0;
    boolean playGame = true;
    String restart;
    Scanner scan = new Scanner(System.in);
    
while(playGame == true)
{
    while (playGame == true) 
    {
        System.out.println("Enter a number between 1 and 100: ");
        guess = scan.nextInt();
        guessCount ++;
        
        System.out.println(answer);
        
        if (guess < 1 || guess > 100) 
        {
            System.out.println("You have entered an invalid number.");
            guessCount --;
        } else if (guess == answer) 
        {
            System.out.println("Correct! Great guess! It took you " + guessCount + " tries!");
            break;
        } else if (guess > answer) 
        {
            System.out.println("You've guessed too high! Guess again: ");
        } else if (guess < answer)
        {
            System.out.println("You've guessed too low! Guess again: ");
        }
    }
    
    System.out.println("Would you like to play again? Y/N");
    restart = scan.next();
    
    if (restart.equalsIgnoreCase("Y")) 
    {
        playGame = true;
    } else if(restart.equalsIgnoreCase("N"))
    {
        System.out.println("Thank you for playing!");
        break;
    }
}

Answer 1

变量 'answer' 中的值保持不变，因为变量是对您存储/初始化或分配的内容的引用。它本身不操纵。您必须重写代码，例如answer = (int)(Math.random()*100+1) 在游戏重新开始之前或之后。

Answer 2

你在循环之前初始化 answer，它永远不会改变。当用户选择玩新一轮时，您必须分配 answer 一个新值。这不是我要写的代码，但它是：

if (restart.equalsIgnoreCase("Y")) 
{
    answer  = (int)(Math.random() * 100 + 1);
}
