求java的图书购买系统，最好是新做的可以运行的完整代码， 毕业做，我已经崩溃了，
一定要用javajava图书购买系统代码的桌面程序做java图书购买系统代码？不死才怪呢。如果可以用web框架做java图书购买系统代码，快多了。哎java图书购买系统代码，中国的大学教育……问问老师能不能用web框架做,不过楼主也得会框架才行……你自己觉得难，别人也难啊，试问哪有现成的呢？

Q4: JAVA编程图书管理系统购物车
楼主 最简单的就是把 用户放入购物车的商品编号 存入到session
你可以做一类 属性 id//商品编号 num //购买数量 name //商品名称 price //商品价格 简单的就这样用就差不多
点击放入购物车 你可以用ajax session.setAttribute("定义名称",放入商品对象); //你可以在这判断下如果存在你就把 num+1;
点击查看购物车 你就把sesssion.getAttribute("定义名称") 循环出来就可以了 总价格就把 num*price
所有总价格就循环时 把总价格加在一起即可
你用百度hi我发送给你
