java - 为什么我的代码永远运行？它只是一堆带有应该递减的整数的 for 循环？

Question

我编写了一些代码来打印记分牌，但它没有完成运行。记分板应该如下所示

+-----+-----+-----+-----+-----+-----+-----+-----+-----+
|\\ //|\\ //|\\ //|\\ //|\\ //|\\ //|\\ //|     |     |
| \V/ | \V/ | \V/ | \V/ | \V/ | \V/ | \V/ |     |     |
| /.\ | /.\ | /.\ | /.\ | /.\ | /.\ | /.\ |     |     |
|// \\|// \\|// \\|// \\|// \\|// \\|// \\|     |     |
+-----+-----+-----+-----+-----+-----+-----+-----+-----+

但是当我使用错误猜测的数字运行它时，它会永远运行，而当我使用错误猜测的零运行它时，记分板看起来像这样

+-----+-----+
+-----+-----+
|     |     |
|     |     |
|     |     |
|     |     |
|     |     |
|     |     |
|     |     |
|     |     |
+-----+-----+
+-----+-----+

这是我的代码:

public class PhraseGame {

    public static String drawScoreboard(int totalGuesses, int incorrectGuesses) {
        String result = "";
        String finalResult = "";

        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("+-----");
                finalResult += result;
            }
            for (int i = totalGuesses - incorrectGuesses; i > 0; i--) {
                result = ("+--a---");
                finalResult += result;
            }
            result = ("+\n");
            finalResult += result;
        }
        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("|\\\\ //");
                finalResult += result;
            }
            for (int h = totalGuesses - incorrectGuesses; h > 0; h--) {
                result = ("|     ");
                finalResult += result;
            }
            result = ("|\n");
            finalResult += result;
        }
        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("| \\V/ ");
                finalResult += result;
            }
            for (int i = totalGuesses - incorrectGuesses; i > 0; i--) {
                result = ("|     ");
                finalResult += result;
            }
            result = ("|\n");
            finalResult += result;
        }
        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("| /.\\ ");
                finalResult += result;
            }
            for (int i = totalGuesses - incorrectGuesses; i > 0; i--) {
                result = ("|     ");
                finalResult += result;
            }
            result = ("|\n");
            finalResult += result;
        }
        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("|// \\\\");
                finalResult += result;
            }
            for (int i = totalGuesses - incorrectGuesses; i > 0; i--) {
                result = ("|     ");
                finalResult += result;
            }
            result = ("|\n");
            finalResult += result;
        }
        for (int j = totalGuesses; j > 0; j--) {
            for (int g = incorrectGuesses; incorrectGuesses > 0; g--) {
                result = ("+-----");
                finalResult += result;
            }
            for (int i = totalGuesses - incorrectGuesses; i > 0; i--) {
                result = ("+-----");
                finalResult += result;
            }
            result = ("+");
            finalResult += result;
        }
        result = "\n";
        finalResult += result;
        return finalResult;
    }

    public static void main(String[] args) {
        System.out.println(PhraseGame.drawScoreboard(4,2));
    }


}

我是不是哪里搞错了？

Answer 1

您对总猜测次数进行了两次循环。

第一层循环for (int j =totalGuesses; j > 0; j--) 循环猜测总数一次，而第二层循环in CorrectGuesses 和 totalGuesses - invalidGuesses 再次运行猜测总数。

这意味着总共 3 次猜测，您将打印九次，而不是打印三次!这就是为什么输出的每一行都会被打印多次。

除此之外，正如 @ScaryWombat 的答案所示，您的 in CorrectGuesses 循环是不正确的，因为它比较 in CorrectGuesses > 0 而不是比较 g > 0.
