java - 我的猜谜游戏计数器不断上升

Question

所以在类里面我应该做一个猜谜游戏，当你接近答案时为你提供线索。我的问题是，当我运行它并且得到一个正确的数字时，我显然会保留该数字并继续使用其他 4 个数字，当我这样做时，问题是我的正确数字计数器不断上升，即使我没有得到其他数字正确..我该如何解决这个问题？我是否可以在每个 if 语句中添加中断，或者是否可以完全退出 do while 循环？

public class GuessingGame {

public static void main(String[] args) {
    int guess,numDigitsCorrect=0,sumDigitsCorrect=0,attempts=0,answer;
    Random rng = new Random();
    Scanner consoleScanner = new Scanner(System.in);
    answer = rng.nextInt(90000) + 10000;
    System.out.println("I have randomly chosen a 5-digit code for you to guess.Each time you guess,\n"
            +   "I will tell you how many digits are correct and the sum of the digits that are correct."
            +   "For example, if the number is \"68420\" and you guess 12468, I will respond:\n"
            +   "Number of Digits Correct: 1\n"
            +   "Sum of Digits Correct: 4\n"
            +   "From deduction, you will know the 4 was correct in the guess."
            +   "\nNow its your turn..................................................................");
    do{
        System.out.print("Please enter a 5-digit code (your guess): ");
        guess = consoleScanner.nextInt();
        int g1 = guess/10000;
        int g2 = guess%10000/1000;
        int g3 = guess % 10000 % 1000 / 100;
        int g4 = guess % 10000 % 100 /10;
        int g5 = guess % 10000 % 10 / 1;
        int a1 = answer/10000;
        int a2 = answer%10000/1000;
        int a3 = answer % 10000 % 1000 / 100;
        int a4 = answer % 10000 / 100 / 10;
        int a5 = answer % 10000 % 10 / 10;
        if(g1 == a1)
        {
            numDigitsCorrect ++;
            sumDigitsCorrect += a1;
            System.out.println("\nNumber of digits correct: " + numDigitsCorrect) ;
            System.out.println("Sum of digits correct: " + sumDigitsCorrect);
            System.out.println();
        }
        if(g2 == a2)
        {
            numDigitsCorrect ++;
            sumDigitsCorrect += a2;
            System.out.println("Number of digits correct: " + numDigitsCorrect) ;
            System.out.println("Sum of digits correct: " + sumDigitsCorrect);
            System.out.println();
        }
        if (g3 == a3)
        {
            numDigitsCorrect ++;
            sumDigitsCorrect += a3;
            System.out.println("Number of digits correct: " + numDigitsCorrect) ;
            System.out.println("Sum of digits correct: " + sumDigitsCorrect);
            System.out.println();
        }
        if (g4 == a4)
        {
            numDigitsCorrect ++;
            sumDigitsCorrect += a4;
            System.out.println("Number of digits correct: " + numDigitsCorrect) ;
            System.out.println("Sum of digits correct: " + sumDigitsCorrect);
            System.out.println();
        }
        if (g5 == a5)
        {
            numDigitsCorrect ++;
            sumDigitsCorrect += a5;
            System.out.println("Number of digits correct: " + numDigitsCorrect) ;
            System.out.println("Sum of digits correct: " + sumDigitsCorrect);
            System.out.println();
        }
        if(guess == answer)
        {
            System.out.println("****HOORAY!  You solved it.  You are so smart****");
            break;
        }
    }while (guess != answer);

}

}

Answer 1

有一些问题需要修复 -

1. 确保您的 a4、a5 正确

   int a4 = answer % 10000 % 100 / 10; // note the modulus
   
   int a5 = answer % 10000 % 10; // note divided by 1 or remove the redundant statement
   

2. 将 print 语句从 if block 移至 do block 内所有 if 的末尾，如下所示 -

   if (g1 == a1) {
           numDigitsCorrect++;
           sumDigitsCorrect += a1;
   }
   ... //other if statements
   if (guess == answer) {
       System.out.println("****HOORAY!  You solved it.  You are so smart****");
       break;
   }
   System.out.println("Number of digits correct: " + numDigitsCorrect);
   System.out.println("Sum of digits correct: " + sumDigitsCorrect);
   

3. 而且由于您已经进行了检查

   if (guess == answer) {
       System.out.println("****HOORAY!  You solved it.  You are so smart****");
       break;
   }
   

   在您的 do 中，您可以将 while 条件更改为 true 作为 -

   do {
    ... your existing code
    } while(true);
   

4. 回答

Would i be able to add breaks in each of the if statements

如果你这样做，即使是一个数字匹配，你的循环也会退出(中断)。

重要的是要修复计数器，请将 do block 内的计数器初始化为

do {
    numDigitsCorrect = 0;
    sumDigitsCorrect = 0;
.. // existing logic
}
