通信软件设计实验报告VIP免费

这个软件主要功能是以UDP为基础实现两台电脑之间收发简单文本消息。软件全部使用java编写，并以JavaBuilder8为工具进行编写与调试。布局方式采用NULL方式,主要使用AWT的组件和部分SWING的组件。使用方法如下：1首先在输入IP地址的输入栏中输入想与之进行通信的主机的IP地址，即消息接受方的IP地址。2在消息编辑框中输入想发送的消息内容。3编辑完欲发送的消息后，点击“发送消息”按钮进行发送；4双方发送的消息和发送方与接受方的IP地址都会在下面的空白区域----“频道”内显示。6如果没有输入IP地址便发送编辑完的文本消息，空白区域内会显示出提示信息提示用户应输入接受方的IP地址。7当频道内显示的消息太多时,可以按”刷新频道”来清除频道内全部信息!软件运行时候的抓图：本机测试结果的抓图效果程序代码与简要说明1chatFrame类的代码:packagechat;importjava.net.*;importjava.io.*;importjava.awt.*;importjava.awt.event.*;importjavax.swing.*;/***
