//Name Price * Number
//Id = Money
//--------------------

//goodsItem goodsNumber
//goodsMoney
分析:
- 品名:Name,String
- 商品编号:Id,String
- 售价:Price,double
- 数量:Number,int
- 金额:Money,double
- --------------------------
- _项商品:goodsItem,int
- 共计:_件:goodsNumber,int
- 总计:goodsMoney,double
public class SuperMarketTicket {

//定义

double bMoney = bPrice * bNumber;
String cName = "c";
String cId = "(003)";
double cPrice = 3.3;
int cNumber = 3;
double cMoney = cPrice * cNumber;
//计算:_项商品
int goodsItem = 3;
//计算:共计:_件
int goodsNumber = aNumber + bNumber + cNumber;
//计算:总计:_
double goodsMoney = aMoney + bMoney + cMoney;
//打印
