我正在制作一个**猜字游戏*

Player1输入一个神秘单词，然后输出该单词中的字母数

然后在while循环中，player2猜测单词，如果它们不是神秘单词，则一条语句说“短语不是神秘单词”，，但当player2猜测神秘单词时，以下应为输出，如下面的打印语句所示：

else if (phrase.equals(mysteryphrase)){
    go = false;
    counter--;
    int points = (mysteryphrase.length()*10-counter*5);
    System.out.println("Correct! The mystery word is"+mysteryphrase+".");
    System.out.println("You made "+counter+" incorrect guesses");
    System.out.println("You get "+points+" points");
我让它工作，但另一个要求是，当它达到神秘词长度的两倍时，游戏应该停止，它应该说：

else if (counter2 == mysteryphrase.length()*2){
    go = false;
    System.out.println("\n"+"You made "+counter2+" incorrect guesses");
    System.out.println("You get 0 points");
    System.out.println("You lost the game");
}
我面临的问题是，有一个计算点的公式：

Points = (number of letters in the word * 10 - incorrect guesses *5)
当游戏在两倍神秘词长度后停止时，此选项有效，但当玩家2正确猜出神秘词时，此选项无效。为什么呢

对于那些感兴趣的人，这是我的全部代码：

import java.util.Scanner;
public class Wordguess{
public static void main(String[]args){
Scanner keyboard = new Scanner(System.in);
    int option = Integer.parseInt(keyboard.nextLine());
    String mysteryphrase = keyboard.next();
        System.out.print("The mystery word has "+mysteryphrase.length()+" letters"+".");
        if (option == 1){
            boolean go = true;
            while (go){
                String phrase = keyboard.next();
                if (!phrase.equals(mysteryphrase)){
                    System.out.print("The mystery word is not "+phrase+".");
                }
                else if (phrase.equals(mysteryphrase)){
                    go = false;
                    System.out.print("Correct! The mystery word is "+mysteryphrase+".");
                }
            }
        }
        else if (option == 2){
            int counter = 1;
            boolean go = true;
            while (go){
                String phrase = keyboard.next();
                if (!phrase.equals(mysteryphrase)){
                    System.out.print("The mystery word is not "+phrase);
                    counter++;
                }
                else if (phrase.equals(mysteryphrase)){
                    go = false;
                    counter--;
                    int points = (mysteryphrase.length()*10-counter*5);
                    System.out.println("Correct! The mystery word is"+mysteryphrase+".");
                    System.out.println("You made "+counter+" incorrect guesses");
                    System.out.println("You get "+points+" points");
                }
            }
        }
        else if (option == 3){
            int counter = 1;
            int counter2 = 0;
            boolean go = true;
            while (go){
                String phrase = keyboard.next();
                if (!phrase.equals(mysteryphrase)){
                    System.out.print("The mystery word is not "+phrase);
                    counter++;
                    counter2++;
                }
                else if (phrase.equals(mysteryphrase)){
                    go = false;
                    counter--;
                    int points = (mysteryphrase.length()*10-counter*5);
                    System.out.println("Correct! The mystery word is"+mysteryphrase+".");
                    System.out.println("You made "+counter+" incorrect guesses");
                    System.out.println("You get "+points+" points");
                }
                else if (counter2 == mysteryphrase.length()*2){
                    go = false;
                    System.out.println("\n"+"You made "+counter2+" incorrect guesses");
                    System.out.println("You get 0 points");
                    System.out.println("You lost the game");
                } 
            }
        }
    }
}
正如你所见，我使用了两个计数器，一个用于赢，一个用于检查神秘单词长度是否加倍，游戏结束。当玩家2猜对时，“计数器”似乎不适用于点数

以下是我的输出，该输出不适用于点：

你得5分
应该是在玩家正确猜测后和5次猜测后：

你得70分
如果用户输入3作为选项，则您有以下代码

if（！phrase.equals（mysteryphrase））{
那你有

else if（短语.equals（mysteryphrase））{
之后你有

else if（counter2==mysteryphrase.length（）*2）{
如果，您将永远不会输入最后一个
else。用户输入的单词可能是神秘单词，也可能不是。没有第三个选项。也许您只需要删除最后一个else并将其设置为


if（counter2==mysteryphrase.length（）*2）{


编辑
实际上，您需要在每次错误猜测后立即检查
counter2
的值，因此初始条件应为


if（！phrase.equals（mysteryphrase））{
系统输出打印（“神秘词不是”+短语）；
计数器++；
计数器2++；
if（counter2==mysteryphrase.length（）*2）{
go=假；
System.out.println（“\n”+“您做出了”+counter2+“错误的猜测”）；
System.out.println（“得0分”）；
System.out.println（“你输掉了比赛”）；
} 
}

适用于您的程序的简短代码：


import java.util.*;
public class GFG{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the mystery word");
        String mystery=sc.nextLine();
        int counter=0;
        while(counter<mystery.length()*2){
            System.out.println("Guess the mystery word!");
            String guess=sc.nextLine();
            if(guess.equals(mystery))
                break;
            counter++;
        }
        if(counter==mystery.length()*2)
            System.out.println("You made "+counter+" incorrect guesses so your score is 0");
        int score=mystery.length()*10-counter*5;
        System.out.println("You made "+counter+" incorrect guesses and your score is "+score);
    }
}



else if (counter2 == mysteryphrase.length()*2){
    go = false;
    System.out.println("\n"+"You made "+counter2+" incorrect guesses");
    System.out.println("You get 0 points");
    System.out.println("You lost the game");
}



import java.util.*；
公共类GFG{
公共静态void main（字符串[]args）{
扫描仪sc=新的扫描仪（System.in）；
System.out.println（“输入神秘词”）；
字符串奥秘=sc.nextLine（）；
int计数器=0；

而（计数器以下代码将永远不会在您的程序中执行：


import java.util.*;
public class GFG{
    public static void main(String[] args){
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter the mystery word");
        String mystery=sc.nextLine();
        int counter=0;
        while(counter<mystery.length()*2){
            System.out.println("Guess the mystery word!");
            String guess=sc.nextLine();
            if(guess.equals(mystery))
                break;
            counter++;
        }
        if(counter==mystery.length()*2)
            System.out.println("You made "+counter+" incorrect guesses so your score is 0");
        int score=mystery.length()*10-counter*5;
        System.out.println("You made "+counter+" incorrect guesses and your score is "+score);
    }
}



else if (counter2 == mysteryphrase.length()*2){
    go = false;
    System.out.println("\n"+"You made "+counter2+" incorrect guesses");
    System.out.println("You get 0 points");
    System.out.println("You lost the game");
}


原因是，当您检查时，
如果（！phrase.equals（mysteryphrase））
，则它将是
真的
或
假的
，因此
否则如果
不仅没有意义，而且还会导致您面临的混乱和问题
