Question

这是我制作的猜谜游戏的代码。我的计数器没有增加到1以上。我正在从单独的控制器类传递参数choice和generateNumber。 do while循环是否应该在控制器类中？

            public String startGuessingGame(int choice, int generatedNumber) {

        int count = 0;
        final int attempts = 4;
        String result = null;

            do {

                count++;

                if (choice == generatedNumber) {

                    result = "Attempt " + count + " "
                            + "- You have guessed the correct number!";

                }

                else if (choice > 50 || choice < 0) {

                    result = "Out of range. "
                            + "\nPlease choose a number between 1 and 50."; 

                }

                else if (choice > generatedNumber) {

                    result = "Attempt " + count + " " 
                            + " - You have guessed too high!";

                }

                else if (choice < generatedNumber) {

                    result = "Attempt " + count + " " 
                            + "- You have guessed too low!";

                }


                if (count == attempts) {

                    result = "You are out of guesses! The number was " + generatedNumber;

                }
            }

        while(count < attempts);

            return result;

    }
}

Answer 1

这里没有循环。您正在寻找类似InternalsVisibleTo之类的东西。

Answer 2

您需要将count设置为控制器类的类变量（成员），并在该类中执行do / while循环，以便startGuessingGame仅处理用户选择的验证。像这样的东西，但是代码还远远不够完整

public class SomeControllerClass() {
    final int attempts = 4;
    int count = 0;

    public void someMethod() {
        int choice = 0;
        do {
            choice = getChoice();
            count++;
            String text = otherClass.startGuessingGame(choice, generatedNumber);
        while (count < attempts);
    }

并且该方法仅进行验证

public String startGuessingGame(int choice, int generatedNumber) {
    String result = null;

    if (choice == generatedNumber) {
        result = "Attempt " + count + " "
                        + "- You have guessed the correct number!";
    } else if (choice > 50 || choice < 0) {
    //and so on
   return result;
}

尝试一下：在while条件之前的最后增加计数器：

do{
    ...
    if (count == attempts) {

        result = "You are out of guesses! The number was " + generatedNumber;

    }
    count++;
}while(count < attempts);

return result;

...

猜游戏循环
