這個軟件主要功能是以UDP為基礎(chǔ)實現(xiàn)兩臺電腦之間收發(fā)簡單文本消息。軟件全部使用java編寫，并以JavaBuilder8為工具進(jìn)行編寫與調(diào)試。布局方式采用NULL方式,主要使用AWT的組件和部分SWING的組件。
使用方法如下：
1 首先在輸入IP地址的輸入欄中輸入想與之進(jìn)行通信的
2、主機(jī)的IP地址，即消息接受方的IP地址。
2 在消息編輯框中輸入想發(fā)送的消息內(nèi)容。
3 編輯完欲發(fā)送的消息后，點擊“發(fā)送消息”按鈕進(jìn)行發(fā)送；
4 雙方發(fā)送的消息和發(fā)送方與接受方的IP地址都會在下面的空白區(qū)域----“頻道”內(nèi)顯示。
6 如果沒有輸入IP地址便發(fā)送編輯完的文本消息，空白區(qū)域內(nèi)會顯示出提示信息提示用戶應(yīng)輸入接受方的IP地址。
7 當(dāng)頻道內(nèi)顯示的消息太多時,可以按”刷新頻道”來清除頻道內(nèi)全部信息!
