Question

所以对于我来说，我应该制作一个猜谜游戏，在你接近答案的时候给你提供线索。我的问题是，当我运行它并且我得到一个数字正确时，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＆＃39;得到其他数字正确..我该如何解决这个问题？我是否能够在每个if语句中添加中断，还是会完全退出我的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

很难解决的问题 -

确保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

如果在if区域内，则将您的打印语句从do块移出到所有区域的末尾 -

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);

此外，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，您可以将您的状态更改为true -

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

回答

我是否可以在每个if语句中添加中断

如果这样做，即使是一位数匹配，你的循环也会退出（中断）。

重要的是要修复计数器，将do块中的计数器初始化为

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

我的猜谜游戏计数器不断上升
