简单的35选7彩票系统

实例需求：
用户登录彩票系统de时候需要用户输入自己的身份证号和要选择的7个彩票号码，然后系统给出购买彩票的时间以及个人信息，随后随机产生彩票号码，最后判断是否中奖以及中奖金额。
实例化一个彩票类：
package CaiPiao;

public class LotteryBean {

private String id;private int [] buyno;private String buydate;private  int[] winno;private int wonmoney;// 实例化一个对象来保存彩票信息：public String getId() {    return id;}public void setId(String id) {    this.id = id;}public int[] getBuyno() {    return buyno;}public void setBuyno(int[] buynos) {    this.buyno = buynos;}public String getBuydate() {    return buydate;}public void setBuydate(String buydate) {    this.buydate = buydate;}public int[] getWinno() {    return winno;}public void setWinno(int[] winno) {    this.winno = winno;}public int getWonmoney() {    return wonmoney;}public void setWonmoney(int wonmoney) {    this.wonmoney = wonmoney;}

}
一个测试彩票类：
package CaiPiao;

import java.text.SimpleDateFormat;
import java.util.Scanner;

public class LotteryBeanMethod {
static int sum = 0;
static int[] no = new int[7];
public static LotteryBean mylottery = new LotteryBean();

public static void main(String[] args) {    buyLottery();    getWinno();    getWinMoney();}public static void buyLottery() {    System.out.println("------------购买彩票--------------");    Scanner sc = new Scanner(System.in);    System.out.println("请输入身份证号 :   ");    String id = sc.next();    System.out.println("购买号码：（输入（1-35）的7个数字以逗号隔开）");    String s2 = sc.next();    String[] buynos = s2.split(",");    // 把String类型的数组转换成int 类型的数组    System.out.println("你购买的彩票信息为：");    for (int i = 0; i < buynos.length; i++) {        no[i] = Integer.parseInt(buynos[i]);        System.out.print(no[i] + " ");    }    System.out.println();    // 格式化当前日期    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");    String buydate = sdf.format(new java.util.Date());    System.out.println("购买成功!购买日期为：" + buydate);    mylottery.setId(id);    mylottery.setBuyno(no);    mylottery.setBuydate(buydate);}public static void getWinno() {    System.out.println("------------彩票开奖--------------");    int[] s = new int[7];    for (int i = 0; i < 7; i++) {        int a = (int) (Math.random() * 35) + 1;        s[i] = a;        for (int j = 1; j < i; j++) {            while (s[i] == s[j]) {                i--;            }        }    }    // 输出产生的随机数    System.out.println("开奖号码：");    System.out.println();    mylottery.setWinno(s);    for (int n = 0; n < 7; n++) {        System.out.print(mylottery.getWinno()[n] + " ");    }    int count = 0;    for (int n = 0; n < 7; n++) {        for (int m = 0; m < 7; m++) {            if (mylottery.getWinno()[n] == no[m]) {                count++;            }        }        sum = count;    }    System.out.println();}// 奖金public static void getWinMoney() {    System.out.println("--------兑奖信息--------");    System.out.println("中奖的个数:" + sum);    if (sum == 2) {        System.out.println("中奖金额：" + 5 + "元");    } else if (sum == 3) {        System.out.println("中奖金额：" + 10 + "元");    } else if (sum == 4) {        System.out.println("中奖金额：" + 20 + "元");    } else if (sum == 5) {        System.out.println("中奖金额：" + 40 + "元");    } else if (sum == 6) {        System.out.println("中奖金额：" + 100 + "元");    } else if (sum == 7) {        System.out.println("中奖金额：" + 500 + "元");    } else {        System.out.println("没中奖");    }}

}

这个只是一个简单的系统，不足必然存在欢迎指正。
