功能介绍
通过控制台界面交互，主要实现了乘客购票以及退票流程，管理员对航班信息的管理。
界面如下：
项目结构介绍
- 所有文件如下
说明：其中entity包下放了Flight、Order、User三个实体类，Data是整个项目存放的数据（通过ArrayList来存储数据，没有使用数据库）
enumration包下存放了用户vip等级信息相关内容
Main是程序的主入口
service包下是相关业务的实现
util包下是对service中对数据操作的实现（模拟进行持久化），以及其他的一些功能实现
项目代码
Main
主要以switch做了一个选择界面，选的相应功能调用service函数
package main;
import entity.Data;
import service.FlightService;
import service.Impl.FlightServiceImpl;
import service.Impl.OrderServiceImpl;
import service.Impl.UserServiceImpl;
import service.OrderService;
import service.UserService;
