java 学生宿舍管理系统设计

Question

学生宿舍管理系统设计 
功能：实现简单的学生宿舍基本信息管理，宿舍的基本信息包括楼号、房间号、面积、所容纳人数、已入住人数等 
基本要求： 
1设计简单的菜单，能够进行系统功能选择。 
2实现信息的录入功能。 
3在已有信息的基础上添加新的记录。 
4删除指定房间号的记录。 
5修改指定房间号的记录 
6实现信息的浏览功能 
7按房间号查询功能 
8按已入住人数排序功能

要运用数据库处理，用MySQL5.7.3

该回答通过自己思路及引用到GPTᴼᴾᴱᴺᴬᴵ搜索,得到内容具体如下：
下面是一个简单的学生宿舍管理系统设计的Java代码，实现了上述功能：
在下面的代码中，我们定义了一个Dormitory类来表示一间宿舍，有楼号、房间号、面积、所容纳人数和已入住人数等属性。在DormitoryManagement类中，我们定义了一些方法来实现对宿舍信息的录入、添加、删除、修改、浏览、查询和排序等操作。

在main方法中，我们通过Scanner类来实现用户输入，并通过switch语句来根据用户的选择执行不同的操作。例如，当用户输入1时，程序会调用DormitoryManagement类的input方法来录入宿舍信息；当用户输入5时，程序会调用DormitoryManagement类的showAll方法来浏览所有宿舍信息。

此外，在DormitoryManagement类中，我们还定义了一些辅助方法来实现具体的操作，例如findDormitory方法用于根据房间号查找宿舍信息，sortByOccupied方法用于按已入住人数排序等。这些方法的实现细节可以参考代码中的注释。
