题目

10.针对下面的需求描述，运用面向对象方法设计软件，并用UML表示类之间的关系:个网上购物系统，客户(Customer)可以从商品目录(Category)中浏览商品(Item), 把挑远的商品放进购物车(Shoping cart), 并且可以说明同一商品的数量。如果不如意，也可以随时从购物车拿出一件成若 干商品。客户付款(Paymen)时，系统计算购物车中所有商品的价格，让客户选择E-bao、Bank ceard 或货到付款(Cash)等付款方式。系统根据付款方式和金额为客户增加积分(Reward),井根据年度消费总金额把客户划分成三类: Type_A. Type_B和TypeC.以便你供针对性的服务和营销。客户能河览自己的积分、年采购的所有商品， 但是不知道自己在网站的客户分类。
 

自己写的，可以不看，拒绝诋毁，来之不易，望君珍惜！

基于软件PowerDesinger16.5

 代码如下：
