Question

我的班级代码：http://notepad.cc/lureascu84 我的测试人员代码：http://notepad.cc/mammivo62

我被困在如何导入类程序中的代码以在测试器中使用。在我的简单数字猜测程序中，我有：

while (guess != num){
     guess = scanner.nextInt();

     if (guess > num){
        System.out.println("The number you have entered is too high!");
        numberOfGuesses++;
     }

     if (guess < num){
        System.out.println("The number you have entered is too low!");
        numberOfGuesses++;
     }
  }
  System.out.println("You win with only " + numberOfGuesses + " wrong attempts!");

当使用访问器和mutator方法时，我会坚持写什么。

Answer 1

我相信你所坚持的是实例化GuessingGame(int maxValue)类。您需要创建一个将调用类的构造函数的新对象，然后您将能够执行其中包含的方法。

GuessingGame game = new GuessingGame(10);

上面从测试人员类创建了一个新的GuessingGame对象，类似于创建Random random = new Random()，其中“maxValue”已设置为10.从此处可以进行方法调用。

game.guess(9);

会运行guess(int newGuess)，并且可能会输出用户的猜测太低。

Answer 2

这是我为“随机数猜”游戏制作的程序。尽管代码可能看起来很长，但是非常简单。特点：-

（1）.1到10之间生成一个数字玩家可以通过以下方式重玩游戏：（2）。按'T'或在游戏结束时按'E'退出游戏... （3）。如果播放器输入任何错误的值，程序都不会得到... （4）。终止。玩家可以看到他们尝试的次数...希望能帮助您！
