设计电商类，其中包含商品类，商品类属性（名称、价格、介绍、厂家、生产地址），继承类有食品类、电气类、服装类、玩具类。
食品类属性：有效时长、重量
电气类属性：电压、功率、重量
服装类属性：材质、面料、成分
玩具类属性：材质、分类、适用年龄
要求：
1、设计商品类，封装商品信息
2、设计继承类，继承商品类，封装继承商品信息
3、设计商城，商城中有一个各类商品的集合，客户可以看到所有商品，也可以根据不同继承类查询商品每类商品不少以五种
4、查询商城中价格超过100元的商品
5、查询生产地是“北京”的商品
6、根据商品价格给商城排序，价格从高到低
7、设计购物车，购物车包括商品名称和商品数量，
8、输入商品名称，显示商品信息，输入数量，加入购物车，完成添加后，输入“结账”，计算所有商品价格。
9、设计抽奖功能，查询所有商品，生成随机数，随机数范围0到商品集合长度，生成随机数后，通过下标获取商品，显示商品信息
