我也不明白你为什么要做

guess++

。这没有意义。

修复你的主要方法。你遗漏了一点变量，添加了一个来猜测。你总是检查用户的第一次输入

你为什么要修改从用户那里得到的猜测？我是怎么做的？请解释

guess++

修改你读到的猜测的值，我相信他是在试图跟踪用户给出的猜测数量。操作：将猜测数量分配给另一个

int

@JB Nizet，我是在增加猜测数量从用户那里，所以我给GuessTheNumber分配了一个新值？你复制了代码吗？你可能添加了一个比需要的多的花括号。我编译并运行了它。很抱歉，这是我的错，我现在正在尝试，看看它是否有效。感谢你的帮助，我没有在while循环后添加花括号。愚蠢的错误

public static void main(String[] args) {

    GuessTheNumberGame game = new GuessTheNumberGame(100);
    int turns = 0;

    Scanner kb = new Scanner(System.in);

    // TODO 4: loop as long as the guess is not correct
    while (true) {
        System.out.println("Guess a nummber between 0 and 100");
        int guess = kb.nextInt();
        if (game.isGuessHigher(guess)) {
            System.out.println("You guessed too high!");
        } else if (!game.isGuessCorrect(guess)) {
            System.out.println("You guessed too low!");
        }
        turns++;
        if (game.isGuessCorrect(guess)) break;
    }

    // TODO 5: in the loop, check guesses and give hints

    System.out.printf("You guessed the number in %d turns\n", turns);
