java课程设计--聊天软件(带源码)(可编辑修改word版)

5. 实验方法与步骤：

这个软件从0.1 到1.3 一共13 个版本。0.1 到0.4 版本为客户端界面设计，第0.5 到1.2 版本为服务器端设计以及客户端与服务器端通信连接的设计实现。1.3 版为完善之前版本的缺陷并添加登陆界面。

最终版本1.3 版中一共三个类（如图一所示）

源代码如下：

//客户端

public class ChatClient extends Frame

add(taContent, BorderLayout.NORTH);

pack();

this.addWindowListener(new WindowAdapter() {
