java - 制作彩票

产生一个三位数的彩票。该程序提示用户输入一个三位数的数字，然后
根据以下规则确定用户是否获胜：
（规则1）。如果用户输入的彩票号码与确切顺序相符，则奖励为
$ 10,000。
（规则2）。如果用户输入中的所有数字与彩票号码中的所有数字匹配，则奖励为
$ 3,000。
（规则3）。如果用户输入中的一位数字与彩票号码中的一位数字匹配，则奖励为
$ 1,000。

我需要帮助，以使程序在代码中看到的所有内容都能按预期运行。没有数组，没有字符串，只有已经存在的东西。我的问题是我无法猜测110来忽略规则2。我将其设置为100以测试所有规则。

import java.util.Scanner;

public class NewClass {
    public static void main(String[] args) {
        int lottery = 100;

 // Prompt the user to enter a guess
        Scanner input = new Scanner(System.in);
        System.out.print("Enter your lottery pick (three digits): ");
        int guess = input.nextInt();

 // Get digits from lottery
        int lotteryDigit1 = lottery / 100;
        int lotteryDigit2 = (lottery % 100) / 10;
        int lotteryDigit3 = lottery % 10;

 // Get digits from guess
        int guessDigit1 = guess / 100;
        int guessDigit2 = (guess % 100) / 10;
        int guessDigit3 = guess % 10;

        System.out.println("The lottery number is " + lottery);

 // RULE1 Check the guess
        if (guess == lottery)
            System.out.println("Exact match: you win $10,000");
 // RULE2
        else if ((guessDigit1 == lotteryDigit1
            || guessDigit1 == lotteryDigit2
            || guessDigit1 == lotteryDigit3)
            && (guessDigit2 == lotteryDigit1
            || guessDigit2 == lotteryDigit2
            || guessDigit2 == lotteryDigit3)
            && (guessDigit3 == lotteryDigit1
            || guessDigit3 == lotteryDigit2
            || guessDigit3 == lotteryDigit3))
            System.out.println("Match all digits: you win $3,000");
    // RULE3
        else if ((guessDigit1 == lotteryDigit1
            || guessDigit1 == lotteryDigit2
            || guessDigit1 == lotteryDigit3)
            || (guessDigit2 == lotteryDigit1
            || guessDigit2 == lotteryDigit2
            || guessDigit2 == lotteryDigit3)
            || (guessDigit3 == lotteryDigit1
            || guessDigit3 == lotteryDigit2
            || guessDigit3 == lotteryDigit3))
            System.out.println("Match one digit: you win $1,000");

        else
            System.out.println("Sorry, no match");
    }
 }

更新：

import java.util.Scanner;
    public class NewClass {
        public static void main(String[] args) {
        int lottery = 456;

 // Prompt the user to enter a guess
        Scanner input = new Scanner(System.in);
        System.out.print("Enter your lottery pick (three digits): ");
        int guess = input.nextInt();

 // Get digits from lottery
        int lotteryDigit1 = lottery / 100;
        int lotteryDigit2 = (lottery % 100) / 10;
        int lotteryDigit3 = lottery % 10;

 // Get digits from guess
        int guessDigit1 = guess / 100;
        int guessDigit2 = (guess % 100) / 10;
        int guessDigit3 = guess % 10;

        System.out.println("The lottery number is " + lottery);

  // Sum up both sets of digits to compare for 3 inconsecutive matches
        int guessSum = guessDigit1 + guessDigit2 + guessDigit3;
        int lotterySum = lotteryDigit1 + lotteryDigit2 + lotteryDigit3;

 // RULE1 Check the guess
        if (guess == lottery)
            System.out.println("Exact match: you win $10,000");
 // RULE2
        else if ((guessDigit1 == lotteryDigit1
            || guessDigit1 == lotteryDigit2
            || guessDigit1 == lotteryDigit3)
            && (guessDigit2 == lotteryDigit1
            || guessDigit2 == lotteryDigit2
            || guessDigit2 == lotteryDigit3)
            && (guessDigit3 == lotteryDigit1
            || guessDigit3 == lotteryDigit2
            || guessDigit3 == lotteryDigit3)
            && guessSum == lotterySum)
            System.out.println("Match all digits: you win $3,000");
// RULE3
        else if ((guessDigit1 == lotteryDigit1
            || guessDigit1 == lotteryDigit2
            || guessDigit1 == lotteryDigit3)
            || (guessDigit2 == lotteryDigit1
            || guessDigit2 == lotteryDigit2
            || guessDigit2 == lotteryDigit3)
            || (guessDigit3 == lotteryDigit1
            || guessDigit3 == lotteryDigit2
            || guessDigit3 == lotteryDigit3))
            System.out.println("Match one digit: you win $1,000");

        else
            System.out.println("Sorry, no match");
    }
 }

这似乎最重要。我一直在浏览数字以检验猜测。我没有遇到错误的猜测。 && guessSum == lotterySum)仅与RULE2一起使用。

最佳答案

我认为问题在于您没有考虑重复数字。您可以检查以确保所有数字加起来都等于样本编号，即：

1+1+0 = 2
1+0+0 = 1
1!=2
Move onto rule 3.

使用此代码：

guessDigit1  + guessDigit2 + guessDigit3 == lotteryDigit1 + lotteryDigit2 + lotteryDigit3

我不知道这是否可以解决您的所有问题，但这只是一个开始，应该以110值解决您的直接问题。祝好运！
