时间安排
以下是我的时间安排：
| 10月27日 |
需求分析、功能设计、界面设计、数据库设计 |
| 10月28日 |
弄清JAVA的布局、容器、监听器等层次、关系和作用，主界面代码实现 |
| 10月29日 |
连接数据库，登录、注册界面和功能实现，顾客、厨师身份区别 |
| 10月30日 |
面条、小菜的图片绘制 |
| 10月31日 |
利用POI读写Excel文件，一键配置菜单功能实现，且保存菜单到数据库 |
| 11月1日 |
堂吃和订座的选座功能实现（桌号状态连接数据库记录） |
| 11月2日 |
顾客的菜单界面实现，从数据库读取菜单 |
| 11月3日 |
实现顾客从菜单最后一列输入购买数量的功能，监听表格被修改的内容，保存到数据库（即生成订单） |
| 11月4日 |
实现厨师查看、编辑、删除订单的功能 |
| 11月5日 |
测试与改进 |
代码清单
写了三十多个.java文件，实在懒得一个个打开复制粘贴代码了，而且全放进来的话估计至少有五千行，也看不过来，所以我只放几个核心的。
