【问题描述】：

当猜对后输入数字 0 时，它应该重玩游戏。它只是返回消息“0 再次播放，1 退出”

public static void main(String[] args) 
    boolean game = true; //true means the game will continue playing, false stops the game
    Scanner input = new Scanner(System.in);
    System.out.println("Guess: ");
    while (game) 
        HiLo mainGame = new HiLo();
        mainGame.generateRandomNumber();
        boolean guessCorrect = false;
        while (!guessCorrect) 
            int inputted = input.nextInt();
            if (inputted == 101) 
                guessCorrect = true;
                System.out.println("quitted");
            
            System.out.println(mainGame.checkGuess(inputted));
            mainGame.getGuessCounter();
            if (mainGame.checkGuess(inputted) == "Correct! You got it right!") 
                guessCorrect = true;
                System.out.println("Correct after " + mainGame.getGuessCounter() + " guesses");
            
        
        while (guessCorrect = true) 
            System.out.println("Would you like to play again? (0 : YES) (1 : NO)");
            System.out.println("Your answer: ");
            int answer = input.nextInt();
            //issues with inputting 0 and restarting game
            if (answer == 0) 
                game = true;
            
            else if (answer == 1) 
                guessCorrect = true;
                System.out.println("Game Over");
            
            else 
                System.out.println("Error, can't understand the meaning"); 
                guessCorrect = false;
            
        
    

【问题讨论】：

while (guessCorrect = true) 那应该只是while (guessCorrect)

if (mainGame.checkGuess(inputted) == "Correct! You got it right!") 我找不到方法 checkGuess 的代码，但我认为它返回一个字符串。请参考How do I compare strings in Java

嗨，OP。让我们知道答案是否有帮助。如果它回答了您的问题，请接受它。这样其他人就知道你已经（充分地）得到了帮助。另见What should I do when someone answers my question?

【参考方案1】：

将while (guessCorrect = true) 更改为while (guessCorrect)。将guessCorrect 设置为false 以退出while (guessCorrect) 循环并继续重新启动或退出游戏。如果answer不等于0，请确保将game设置为false以退出游戏。

        while (guessCorrect) 
            System.out.println("Would you like to play again? (0 : YES) (1 : NO)");
            System.out.println("Your answer: ");
            int answer = input.nextInt();
            //issues with inputting 0 and restarting game
            if (answer == 0) 
                game = true;
            
            else if (answer == 1) 
                System.out.println("Game Over");
                game = false;
            
            else 
                System.out.println("Error, can't understand the meaning"); 
                game = false;
            
            
            guessCorrect = false;
