1.在设备管理系统中，为了统一各种设备的编程规范，需要定义一个设备接口（IDevice），在该接口中描述了有关设备的启动（Start）、停止（Stop）、维修（Mainta）、工作（Run）、检测状态（CheckStatus）等功能或行为。请完成该设备接口的定义。
2.接上题，为了进一步简化各种设备的编程工作量，需要在设备接口基础之上派生出抽象类（Device），该类包含设备编号、名称、使用者姓名、场所、购买日期等信息，但因为无法实现接口，所以必须把接口中的成员再描述为抽象成员。请完成该设备类的定义。
3.接上题，在设备类的基础之上派生出手机类Mobile，实现启动、停止、维修、工作和检测状态功能。请完成手机设备类的定义。
提示只需模拟手机设备的各个功能。
