Java 编写飞鸽传书系统窗体程序完整源码

Myth丶恋晨 2024-03-26 07:25 21阅读 0赞

今天为大家分享简单的飞鸽传书程序的开发与制作，目前系统已经完成了初步功能，后续会进一步完善。整个系统界面漂亮，有完整源码，希望大家可以喜欢。喜欢的帮忙点赞和关注。一起编程、一起进步

## **开发环境** ##

开发语言为Java，开发环境Eclipse或者IDEA都可以。运行主程序，或者执行打开JAR文件即可以运行本程序。

## **系统框架** ##

利用JDK自带的SWING框架开发，不需要安装第三方JAR包。纯窗体模式，直接运行Main文件即可以。同时带有详细得设计文档。

## 程序主要功能 ##

### 运行方法 ###

1 运行AppStart.java文件

2 程序出现飞鸽传书的面板

### 系统主要功能点 ###

1发送文字信息，收到方会弹出提醒

2 当发送文件的时候，收到放会弹出提醒，显示文件的名字。点击名字的时候，可以下载相应的文件

## 实现效果 ##
