第二次验收：面向对象与多线程综合实验之GUI设计版本
面向对象与多线程综合实验是一次大项目，总共分为4个部分进行验收，我将分成四个部分展示4个版本的项目工程。希望看到本文章的你，对你有所收获。
文章目录
档案管理系统简介
档案管理系统：用于规范档案文件管理，构建档案资源信息共享服务平台，为用户提供完整的档案管理和网络查询功能。
• 系统是一个基于C/S的GUI应用程序
• 使用Java SE开发
• 综合运用面向对象编程的相关知识
系统环境
系统开发环境：JavaSE-12
集成开发工具：Eclipse Java 2019-06
GUI开发插件：Window Builder
系统功能
Swing GUI编程步骤
创建应用程序框架，选定顶层容器
在顶层容器中创建中间容器，将组件加入中间容器；或者将组件直接加入顶层容器中，设定控件属性
选择布局管理器，进行合理布局
实现事件处理程序，与用户交互
以下是本篇文章正文内容，下面案例可供参考
具体实现
Msystem包
Administrator.java
Browser.java
DataProcessing.java
Doc.java
Main.java
Operator.java
User.java
以上代码同第一个版本类似，可参考我的上一篇文章：
面向对象与多线程综合实验——控制台输出版本
Msystem.GUI包
Filemanagement.java
代码如下（示例）：
