主要流程如下:1. 使用WinningNumber()方法随机生成一组1-33的红球号码和1-16的蓝球号码,作为中奖号码。2. 同样使用WinningNumber()方法随机生成一组作为用户号码。3. 判断用户号码中红球和蓝球的中奖情况:
   - 红球判断使用contains()方法检查用户号码的红球是否在中奖号码的红球中。
   - 蓝球直接比较两组号码的第6位(蓝球号码)。4. 根据中奖情况判断中奖级别和奖金:

   - 6红球1蓝球:一等奖6000万
   - 6红球0蓝球:二等奖500万
   - 5红球1蓝球或5红球0蓝球:三等奖3000元
   - 4红球1蓝球或4红球0蓝球:四等奖200元
   - 3红球1蓝球或2红球1蓝球:五等奖10元
   - 1红球1蓝球或0红球1蓝球:六等奖5元
   - 否则:与奖擦肩而过5. 输出中奖信息,包括中奖级别和奖金。这个程序使用了Random类生成随机数,采用数组存储号码,并使用基本方法判断中奖和包含情况。
