我正在编写一个生成随机数的HighLow游戏,然后要求用户猜测它是什么。然后输入将得到“太高”的响应," "太低了,"或"正确。"我把游戏做得很好,但问题是:太高了," "太低了,"并且"纠正"响应必须使用自定义异常类。我已经创建了自定义异常类,但我不知道如何让程序去除异常(任何帮助都非常适合)。我尝试用以下代码替换原始代码,但它甚至没有接近工作:
if (guess < number) {
throw TooLowException;
} else if (guess > number) {
throw TooHighException;
} else {
throw CorrectException;
}
原始代码:
import java.util.Random;
import java.util.Scanner;
public class HelloWorld {
public class TooHighException extends Exception {
}
public class TooLowException extends Exception {
}
public class CorrectException extends Exception {
}
public static void main(String[] args) {
Random random = new Random();
Scanner scanner = new Scanner(System.in);
int number = random.nextInt(100);
int guess = -1;
while (guess != number) {
System.out.print("Enter your guess: ");
guess = scanner.nextInt();
if (guess < number) {
System.out.println("Too low, guess again");
}
else if (guess > number) {
System.out.println("Too high, guess again");
}
else {
System.out.println("Correct, the random number was " + number);
}
}
}
}

异常是类,你必须创建它们的实例,如下所示:
if (guess < number) {
throw new TooLowException();
} else if (guess > number) {
throw new TooHighException();
} else {
throw new CorrectException();
}

不要使用例外来控制流量。这是一个猜谜游戏,三种可能性中没有一个是例外,在考虑了这个类名后,这一点变得非常清楚:CorrectException
。
