java课程设计-彩票购买抽奖程序

一、项目介绍

题目要求

功能要求： 模拟福利彩票36选7，实现彩票的抽奖与中奖通知功能。

1.允许注册用户，用户信息包括用户id,用户名，密码，账户金额，电话号码等属性。

2.允许注册用户购买彩票：手动选号、随机选号，并允许设置投注数。

3.抽奖功能：要求屏幕上能够显示抽奖的号码滚动过程，按“停止”按钮给出抽奖结果。特等奖，7个号码全中。一等奖，6个号码全中。抽出号码后，显示中奖用户id，中奖的倍数。

4.彩票抽奖通知功能：抽出号码后，当用户登录系统后，系统提示是否中奖。

5.设计一自动注册用户(注册10万个)、并自动买彩票为用户买彩票的程序。然后模拟抽奖。

七、项目关键代码

用户登入代码

public Boolean login(int accountnumber, String password) {
		File f = new File();
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		f.userInput(map);
		Collection<User> users = map.values();
		Iterator<User> iterator = users.iterator();
		while (iterator.hasNext()) {
			User eg = iterator.next();
			if ((accountnumber == eg.getId() || accountnumber == eg.getTel()) && password.equals(eg.getPassword())) {
				return true;
			}
		}
		return false;
	}

充值代码

public int recharge(User user, int money) {
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		File f = new File();
		f.userInput(map);
		user.recharge(money);
		Collection<User> users = map.values();
		Iterator<User> iterator = users.iterator();
		int balance = 0;
		while (iterator.hasNext()) {
			User eg = iterator.next();
			if (eg.getId() == user.getId()) {
				balance = eg.getBalance();
				eg.setBalance(user.getBalance());
				break;
			}
		}
		f.userOutput(map);
		return balance;
	}

public void recharge(int money) {// 账户充值
		int totalmoney = money + getBalance();
		setBalance(totalmoney);
	}

开奖代码

public int[] drawLottery() {
		File f = new File();
		Map<Integer, Backstage> map = new LinkedHashMap<Integer, Backstage>();
		int period = f.winNumIntput(map);
		int[] l = new int[7];
		Backstage b = new Backstage(period, l);
		b.setBalls(b.drawLottery());
		map.put(period, b);
		f.winNumOutput(map);
		return b.getBalls();
	}

创建测试代码

public void createtest() {
		File f = new File();
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		Map<Integer, Backstage> map2 = new LinkedHashMap<Integer, Backstage>();
		List<Lottery> arr = new ArrayList<Lottery>();
		f.lotteryInput(arr);
		int n = f.winNumIntput(map2);
		for (int i = 1; i <= 100000; i++) {
			User user = new User(i, "1", "1", 100, i);
			map.put(i, user);
			int[] balls = new int[8];
			Lottery lottery = new Lottery(n, balls);
			lottery.setId(i);
			lottery.testSelect(user);
			arr.add(lottery);
		}
		f.lotteryOutput(arr);
		f.userOutput(map);
	}

开奖测试代码

public void lotterytest() {
		File f = new File();
		Map<Integer, Backstage> map = new LinkedHashMap<Integer, Backstage>();
		List<Lottery> arr = new ArrayList<Lottery>();
		f.lotteryInput(arr);
		int period = f.winNumIntput(map);
		int[] l = new int[7];
		Backstage b = new Backstage(period, l);
		b.setBalls(b.drawLottery());
		for (Lottery eg : arr) {
			if (eg.getPeriod() == period) {
				System.out.println(eg.toString());
				System.out.println("您获得了" + b.getLevel(eg.getBalls(), b.getBalls()) + "等奖");
			}
		}
		map.put(period, b);
		f.winNumOutput(map);
	}

注册代码

public int register(String name, String password, int tel) {
		File f = new File();
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		int count = f.userInput1(map);
		User user = new User(count, name, password, 100, tel);
		map.put(count, user);
		f.userOutput(map);
		return count;
	}

通知中奖代码

File f = new File();
		Map<Integer, Backstage> map11 = new LinkedHashMap<Integer, Backstage>();
		List<Lottery> arr = new ArrayList<Lottery>();
		int n2 = f.winNumIntput(map11) - 1;
		int id = user.getId();
		String str = new String();
		f.lotteryInput(arr);
		Collection<Backstage> winnums = map11.values();
		Iterator<Backstage> iterator1 = winnums.iterator();
		int winballs[] = new int[7];
		while (iterator1.hasNext()) {
			Backstage eg1 = iterator1.next();
			if (eg1.getPeriod() == n2) {
				winballs = eg1.getBalls();
			}
		}
		for (Lottery eg2 : arr) {
			if (eg2.getId() == id && eg2.getPeriod() == n2) {
				str += "中奖号码" + Arrays.toString(winballs) + "\n" + "您的" + eg2.toString() + "\n" + "您获得了"
						+ eg2.getLevel(eg2.getBalls(), winballs) + "等奖" + "\n";
			}
		}
		JOptionPane.showMessageDialog(null, str);

购票代码

手选购票

public void handSelect(User user, int balls[]) {
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		Map<Integer, Backstage> map2 = new LinkedHashMap<Integer, Backstage>();
		File f = new File();
		f.userInput(map);
		int period = f.winNumIntput(map2);
		List<Lottery> arr = new ArrayList<Lottery>();
		Lottery lottery = new Lottery(period, balls);
		lottery.handSelect(user, balls);
		arr.add(lottery);
		f.lotteryOutput(arr);
		Collection<User> users = map.values();
		Iterator<User> iterator = users.iterator();
		while (iterator.hasNext()) {
			User eg = iterator.next();
			if (eg.getId() == user.getId()) {
				eg.setBalance(user.getBalance());
				break;
			}
		}
		f.userOutput(map);
	}

public void handSelect(User user, int balls[]) {// 手动选号
		int count = balls[7];
		int nowbalance = user.getBalance() - count * 2;
		user.setBalance(nowbalance);
		setId(user.getId());
		setBalls(balls);
		setPrice(count * 2);
	}

机选购票

public int[] machineSelect(User user, int count) {
		Map<Integer, User> map = new LinkedHashMap<Integer, User>();
		Map<Integer, Backstage> map2 = new LinkedHashMap<Integer, Backstage>();
		File f = new File();
		f.userInput(map);
		List<Lottery> arr = new ArrayList<Lottery>();
		int period = f.winNumIntput(map2);
		int[] balls = new int[8];
		Lottery lottery = new Lottery(period, balls);
		balls = lottery.machineSelect(user, count);
		lottery.setPeriod(period);
		arr.add(lottery);
		f.lotteryOutput(arr);
		Collection<User> users = map.values();
		Iterator<User> iterator = users.iterator();
		while (iterator.hasNext()) {
			User eg = iterator.next();
			if (eg.getId() == user.getId()) {
				eg.setBalance(user.getBalance());
				break;
			}
		}
		f.userOutput(map);
		return balls;
	}

public int[] machineSelect(User user, int count) {// 机器选号
		Set<Integer> set = new HashSet<Integer>();
		int[] balls = new int[8];
		do {
			int redBall = (int) (Math.random() * 33) + 1;
			set.add(redBall);
		} while (set.size() <= 6);

		int buleBall = (int) (Math.random() * 16) + 1;
		set.add(buleBall);
		int i = 0;
		for (int num : set) {
			balls[i] = num;
			i++;
			if (i == 6) {
				break;
			}
		}
		int blueBall = (int) (Math.random() * 16) + 1;
		balls[6] = blueBall;
		balls[7] = count;
		int nowbalance = user.getBalance() - count * 2;
		user.setBalance(nowbalance);
		setId(user.getId());
		setBalls(balls);
		setPrice(count * 2);
		return balls;
	}

兑奖

public int getLevel(int[] balls, int[] luckyBalls) {
		int level = 0;
		int redCount = 0;
		int blueCount = 0;
		for (int i = 0; i < 7; i++) {
			if (i != 6) {
				for (int j = 0; j < 6; j++) {
					if (balls[i] == luckyBalls[j]) {
						redCount++;
					}
				}
			} else {
				if (balls[6] == luckyBalls[6]) {
					blueCount++;
				}
			}
		}
		if (redCount == 6 && blueCount == 1) {
			level = 1;
		}
		if (redCount == 6 && blueCount == 0) {
			level = 2;
		}
		if (redCount == 5 && blueCount == 1) {
			level = 3;
		}
		if ((redCount == 5 && blueCount == 0) || (redCount == 4 && blueCount == 1)) {
			level = 4;
		}
		if ((redCount == 4 && blueCount == 0) || (redCount == 3 && blueCount == 1)) {
			level = 5;
		}
		if ((redCount == 2 && blueCount == 1) || (redCount == 1 && blueCount == 1)
				|| (redCount == 0 && blueCount == 1)) {
			level = 6;
		}
		return level;
	}

八、程序的不足与改进

此程序使用的是文件的存储，如果使用数据库存储会更方便一些，文件存储读取操作教复杂。界面可以做更多的美化。动态的开奖没有实现，只使用静态开奖的方式。有时间的话会继续完善。
