利用Java实现福彩双色球项目(支持单式/复式购买)

 

买彩票判断是否中奖，中奖后判断是几等奖

双色球投注区分为红色球号码区和蓝色球号码区，

红色球号码区由1-33共33个号码组成，蓝色球号码区由1-16共16个号码组成。

投注时选择6个红球号码和1个蓝球号码组成一注进行单式投注，每注金额2元。

一等奖：投注号码与当期开奖号码全部相同（顺序不限，下同），即中奖；

二等奖：投注号码与当期开奖号码中的6个红色球号码相同，即中奖；

三等奖：投注号码与当期开奖号码中的任意5个红色球号码和1个蓝色球号码相同，即中奖；

四等奖：投注号码与当期开奖号码中的任意5个红色球号码相同，或与任意4个红色球号码和1个蓝色球号码相同，即中奖；

五等奖：投注号码与当期开奖号码中的任意4个红色球号码相同，或与任意3个红色球号码和1个蓝色球号码相同，即中奖；

六等奖：投注号码与当期开奖号码中的1个蓝色球号码相同，即中奖。

显示中奖结果的同时显示您一共下注人民币？？元，累计中奖人民币？？元
