用java写一个双色球项目

好的，以下是一个简单的Java双色球项目示例代码：

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

public class DoubleColorBall {
    public static void main(String[] args) {
        int[] redBalls = new int[6];
        int blueBall;

        // 随机生成6个红球号码
        Random rand = new Random();
        for (int i = 0; i < 6; i++) {
            redBalls[i] = rand.nextInt(33) + 1;
            for (int j = 0; j < i; j++) {
                if (redBalls[i] == redBalls[j]) {
                    i--;
                    break;
                }
            }
        }
        Arrays.sort(redBalls);

        // 随机生成一个蓝球号码
        blueBall = rand.nextInt(16) + 1;

        // 提示用户输入双色球号码
        Scanner input = new Scanner(System.in);
        System.out.print("请输入红球号码（6个数字，用空格隔开）：");
        int[] userRedBalls = new int[6];
        for (int i = 0; i < 6; i++) {
            userRedBalls[i] = input.nextInt();
        }
        Arrays.sort(userRedBalls);
        System.out.print("请输入蓝球号码：");
        int userBlueBall = input.nextInt();

        // 判断中奖情况
        int redCount = 0;
        for (int i = 0; i < 6; i++) {
            if (userRedBalls[i] == redBalls[i]) {
                redCount++;
            }
        }
        boolean blueMatched = (userBlueBall == blueBall);
        int prize = 0;
        if (redCount == 6 && blueMatched) {
            prize = 1;  // 一等奖
        } else if (redCount == 6 && !blueMatched) {
            prize = 2;  // 二等奖
        } else if (redCount == 5 && blueMatched) {
            prize = 3;  // 三等奖
        } else if (redCount == 4 && blueMatched) {
            prize = 4;  // 四等奖
        } else if (redCount == 3 && blueMatched) {
            prize = 5;  // 五等奖
        } else if ((redCount == 5 && !blueMatched) || (redCount == 4 && !blueMatched)) {
            prize = 6;  // 六等奖
        }

        // 输出中奖结果
        System.out.println("中奖号码为：" + Arrays.toString(redBalls) + " + " + blueBall);
        System.out.println("用户输入的号码为：" + Arrays.toString(userRedBalls) + " + " + userBlueBall);
        if (prize > 0) {
            System.out.println("恭喜您中了" + prize + "等奖！");
        } else {
            System.out.println("很遗憾，您没有中奖。");
        }
    }
}

该程序首先随机生成双色球开奖号码，然后提示用户输入号码，并判断用户的号码是否中奖。根据中
