用Java语言完成程序开发,完成的系统应满足以下要求:
货物库存信息(商品编号,商品名称,商品分类,商品单价,库存量)、货物销售信息(订单编号,会员编号,商品编号,商品名称,商品分类,商品单价,销售时间)、工作人员信息(员工编号,员工姓名,员工密码,联系电话)存放在文本文件中,需要时从文件中读取。注:客户身份不需要登录系统,可以直接购物,如果是会员,则结账时记录会员信息,非会员则用同一个编号(编号自拟)。
1、基本功能要求:
1)提供给超市人员的基本功能:显示所有库存商品、添加商品、修改商品、删除商品。
2)提供给客户的基本功能:显示所有库存商品、添加商品到购物车、从购物车删除商品、结账、退出系统。
l显示所有库存商品:从文档中读取数据然后在控制台中显示;
l添加商品:可添加已有商品,添加成功则只需修改数据中的库存值即可,添加新商品则需要在文档中添加一条新记录;
l修改商品:可根据编号修改商品的其他属性信息,如果编号不对,则删除该条记录,重新添加,不可直接修改编号;
l删除商品:可以根据商品编号删除库存记录;
l添加商品到购物车:实现客户往购物车添加商品的功能;
l从购物车删除商品:客户可以从购物车中删除不需要的商品,根据商品编号删除;
l结账:显示购物车中的商品信息列表,并计算购物车中商品的总金额,完成结账后需要修改相应的库存量,还要把销售的商品记录到货物销售信息文档中,清空购物车。
l退出系统:结束程序。
2、中级功能要求:
商品查找功能:该功能超市人员和客户都可用,可以根据商品编号、名称、分类这些属性进行单条件或多条件查询。
3、高级功能要求:
1)实现客户退换货功能:根据订单编号实现商品的退或换的功能,需要相应地修改货物库存信息文档和货物销售信息文档。
2)可以按照商品销售额排序;

是要图形界面程序吗还说是控制台输出那种
推荐一个开源项目
https://github.com/five517/SMBMS
你是要自己开发,需要给你推荐项目,还是?
需要前端页面吗?

请注意,上述代码仅实现了基本功能的框架,仍需根据具体需求进行进一步开发和完善,例如文件读写操作、商品查找功能和高级功能的实现。
回答:可以参考这个超市销售系统,https://gitee.com/anxwefndu/supermarket-sales-system
对于第三点,即高级要求并没有进行合适的实现
java语言开发超时销售系统,可以考虑使用控制台或者swing代码界面的方式实现,这里帮你找到一个开源的超市销售管理系统,使用的是swing实现的,应该可以满足你的需求:
