java模拟彩票中的36选7玩法

好的，以下是一个简单的 Java 程序，用于模拟彩票中的 36 选 7 玩法：

import java.util.Arrays;
import java.util.Random;
import java.util.Scanner;

public class Lottery {
    public static void main(String[] args) {
        int[] lotteryNumbers = generateLotteryNumbers();
        System.out.println("本期彩票中奖号码为：" + Arrays.toString(lotteryNumbers));

        int[] userNumbers = getUserNumbers();
        System.out.println("您选择的号码为：" + Arrays.toString(userNumbers));

        int matchedCount = countMatchedNumbers(lotteryNumbers, userNumbers);
        System.out.println("您中了 " + matchedCount + " 个号码。");

        if (matchedCount == 7) {
            System.out.println("恭喜您中了一等奖！");
        } else if (matchedCount == 6) {
            System.out.println("恭喜您中了二等奖！");
        } else if (matchedCount == 5) {
            System.out.println("恭喜您中了三等奖！");
        } else if (matchedCount == 4) {
            System.out.println("恭喜您中了四等奖！");
        } else {
            System.out.println("很遗憾，您没有中奖。");
        }
    }

    // 生成彩票中奖号码
    private static int[] generateLotteryNumbers() {
        int[] lotteryNumbers = new int[7];
        Random random = new Random();
        for (int i = 0; i < lotteryNumbers.length; i++) {
            int number;
            do {
                number = random.nextInt(36) + 1;
            } while (contains(lotteryNumbers, number));
            lotteryNumbers[i] = number;
        }
        Arrays.sort(lotteryNumbers);
        return lotteryNumbers;
    }

    // 判断数组中是否包含某个元素
    private static boolean contains(int[] array, int element) {
        for (int i : array) {
            if (i == element) {
                return true;
            }
        }
        return false;
    }

    // 获取用户选择的号码
    private static int[] getUserNumbers() {
        Scanner scanner = new Scanner(System.in);
        int[] userNumbers = new int[7];
        System.out.println("请输入您选择的号码（1-36之间的整数）：");
        for (int i = 0; i < userNumbers.length; i++) {
            System.out.print("第" + (i + 1) + "个号码：");
            int number;
            do {
                number = scanner.nextInt();
            } while (number < 1 || number > 36 || contains(userNumbers, number));
            userNumbers[i] = number;
        }
        Arrays.sort(userNumbers);
        return userNumbers;
    }

    // 计算中奖号码个数
    private static int countMatchedNumbers(int[] lotteryNumbers, int[] userNumbers) {
        int count = 0;
        for (int i : userNumbers) {
            if (contains(lotteryNumbers, i)) {
                count++;
            }
        }
        return count;
    }
}

运行程序后，会提示用户输入 7 个号码，然后随机生成彩票中奖号码，并计算用户选择的号码中有多少个与中奖号码相同。最后，根据中奖号码个数，给出相应的中奖提示。
