java实现酒店管理系统

本文实例为大家分享了java实现酒店管理系统的具体代码，供大家参考，具体内容如下

编写环境：MyEclipse2014+sql server2014

系统功能：

1.登录验证
2.房态统计显示
3.预定登记并入库
4.入住登记并入库
5.换房登记并入库
6.客人信息查询
7.退房并入库

运行界面如下：

=====登录界面======
=====主界面=====
=====为每个房间设置弹出菜单======
=====登记界面======

=====换房界面=====
=====退房界面=====

界面之间相关关系：

主界面主要由菜单条，按钮，标签等组成，一个JButton是一个房间，其Test从数据库中获取，颜色由房态决定。
登记-换房-查看信息-退房等界面皆继承一个父类而来，简单快捷。
