简单电影院系统实现

根据要求完成开发喵影院的开发。

1. 定义用户类 User ，包含以下属性：用户的名称（username）、用户登录手机号（phone）、用户的密码（password）、用户的身份（role int类型 1 表示管理员 2 表示普通用户）

2. 定义电影类 Movie ，包含以下属性：电影的名称（name）、电影的价格（price）、电影的导演（director）、上映时间（date int类型，比如：2023年1月1日 写成20230101）。

3. 定义电影院类 MovieTheater ，包含以下属性：电影集合 Movie[] movies; 用户集合 User[] users 用来存储多部电影对象及用户对象。

4. 完成以下功能展示

   • 重写 toString 方法，输出对象的所有信息。

   • 重写 equals 方法

   • 当电影院类中存储电影集合或存储用户的数组超过指定容量时，要进行扩容。

   • 进入系统后可看到如下功能列表：

   • 1. 查询电影信息
   • 1. 显示所有电影信息 (按照评分降序显示)
   • 1. 管理员登录
   • 1. 用户登录
   • 1. 用户注册
   • 1. 退出

     • 用户登录之后可看到如下功能列表：

       • 修改用户信息

       • 查询用户信息

       • 退出

     • 管理员登录可以看到如下功能列表：

     • 新增电影

     • 删除电影（输入电影名称，删除对应电影）

     • 修改电影（输入电影名称，展示电影信息，选择要修改的内容（价格/上映时 间），输入内容，修改已存储的电影信息）

     • 查看所有用户信息

     • 退出

     界面要求

     • 通过控制台输入
     • 通过控制台输出

     注释要求

     • 合理注释
