写一个java彩票游戏代码

以下是一个简单的Java彩票游戏代码示例：

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

public class LotteryGame {
    public static void main(String[] args) {
        int[] lotteryNumbers = generateLotteryNumbers();
        int[] userNumbers = getUserNumbers();

        System.out.println("彩票号码是：" + Arrays.toString(lotteryNumbers));
        System.out.println("你选择的号码是：" + Arrays.toString(userNumbers));

        int matchedNumbers = countMatchedNumbers(lotteryNumbers, userNumbers);
        System.out.println("你猜中了 " + matchedNumbers + " 个号码！");

        if (matchedNumbers == 6) {
            System.out.println("恭喜你中了一等奖！");
        } else if (matchedNumbers == 5) {
            System.out.println("恭喜你中了二等奖！");
        } else if (matchedNumbers == 4) {
            System.out.println("恭喜你中了三等奖！");
        } else {
            System.out.println("很遗憾，你没有中奖。");
        }
    }

    // 生成彩票号码
    public static int[] generateLotteryNumbers() {
        int[] lotteryNumbers = new int[6];
        Random random = new Random();

        for (int i = 0; i < 6; i++) {
            lotteryNumbers[i] = random.nextInt(49) + 1;
        }

        return lotteryNumbers;
    }

    // 获取用户选择的号码
    public static int[] getUserNumbers() {
        int[] userNumbers = new int[6];
        Scanner scanner = new Scanner(System.in);

        System.out.println("请选择6个号码（1-49）：");
        for (int i = 0; i < 6; i++) {
            userNumbers[i] = scanner.nextInt();
        }

        return userNumbers;
    }

    // 计算猜中的号码数量
    public static int countMatchedNumbers(int[] lotteryNumbers, int[] userNumbers) {
        int count = 0;

        for (int i = 0; i < 6; i++) {
            if (lotteryNumbers[i] == userNumbers[i]) {
                count++;
            }
        }

        return count;
    }
}
