基于GUI的网络通信程序的设计说明

./《Java程序设计》实验报告--实验3实验室：2014年12月10日学院计算机与信息学院专业班级姓名成绩课程名称Java程序设计实验项目名称实验三基于GUI的网络通信程序设计指导教师教师评语教师签名：年月日实验目的1．掌握Java中GUI程序的编写,包括事件监听机制.2．掌握Java的网络通信编程,ServerSocket,Socket类的使用.3．掌握Java中多线程的编程,Thread类,Runnable接口的使用.4．掌握用面向对象的方法分析和解决复杂问题.实验原理1.利用java.awt和javax.swing包提供的各种组件实现服务器和客户端的界面设计.2．使用套接字实现基于TCP协议的服务器和客户端.3.为服务器和客户端界面中的有关组件添加消息相应,实现交互.三、使用硬件、软件环境PC计算机一台,配置为CPU为2.6G,内存为4G,硬盘为1T,安装Windows8操作系统.另外,使用JCreator,JDK1.8.0等软件四、实验过程、步骤及原始记录<算法、原程序、测试结果,分析等>1.实验过程：首先实现界面的编写,之后使用套接字实现基于TCP协议的通信,再设置监视器,为相应的组件添加消息相应.2.源程序：1.客户端程序：KeHuDuan.javaimportjava.awt.*;importjava.awt.event.*;importjava.util.*;importjava.io.*;import.*;importjavax.swing.*;publicclassKeHuDuan{ publicstaticvoidmain<String[]args>{ MyFrameclient=newMyFrame<>; client.setVisible<true>; client.setResizable<false>; client.setDefaultCloseOperation<JFrame.DISPOSE_ON_CLOSE>; }}classMyFrameextendsJFrame{ JTextFieldip; JTextFieldport; JTextFieldcin; JTextAreacontent; JButtonconnect; JButtonsay; Socketsocket; MyFrame<>{ init<>; ConnectListencListener=newConnectListen<>; SayListensListener=newSayListen<>; connect.addActionListener<cListener>; say.addActionListener<sListener>; } voidinit<>{ setLayout<newFlowLayout<>>; setSize<400,400>; setLocation<800,100>; add<newJLabel<"Serveip">>; ip=newJTextField<"",8>; add<ip>; add<newJLabel<"Serveport">>; port=newJTextField<"8888",8>; add<port>; connect=newJButton<"connect">; add<connect>; content=newJTextArea<16,35>; JScrollPanescroll=newJScrollPane<content>; add<scroll>; add<newLabel<"Say:">>; cin=newJTextField<25>; add<cin>; say=newJButton<"say">; add<say>; } classConnectListenimplementsActionListener{ intportNum; publicvoidactionPerformed<ActionEvente>{ connect.setEnabled<false>; try{ portNum=Integer.parseInt<port.getText<>>; socket=newSocket<ip.getText<>,portNum>; ClientThreadct=newClientThread<>; ct.start<>; } catch<Exceptionex>{ } } } classSayListenimplementsActionListener{ Stringstr; publicvoidactionPerformed<ActionEvente>{ try{ PrintWriterout=newPrintWriter<newBufferedWriter<newOutputStreamWriter<socket.getOutputStream<>>>,true>; str=cin.getText<>; if<!str.isEmpty<>>{ out.println<str>; content.append<"me:"+str+"\n">; out.flush<>; } cin.setText<"">; } catch<Exceptionex>{ } } } classClientThreadextendsThread{ publicvoidrun<>{ try{ BufferedReaderin=newBufferedReader<newInputStreamReader<socket.getInputStream<>>>; Stringstr; while<true>{ str=in.readLine<>; //System.out.println<"\a">; content.append<str+"\n">; } } catch<Exceptionex>{ } } }}2.服务器端程序：importjava.awt.*;importjava.awt.event.*;importjava.util.*;importjava.io.*;import.*;importjavax.swing.*;publicclassFuWuQi{ publicstaticvoidmain<String[]args>{ MyFrameserve=newMyFrame<>; serve.setVisible<true>; serve.setResizable<false>; serve.setDefaultCloseOperation<JFrame.DISPOSE_ON_CLOSE>; }}classMyFrameextendsJFrame{ JTextFieldport; JButtonstart; JTextAreacontent; JTextFieldcin; JButtonsay; Socketsocket; MyFrame<>{ init<>; StartListensListen=newStartListen<>; SayListenstListen=newSayListen<>; start.addActionListener<sListen>; say.addActionListener<stListen>; } voidinit<>{ setLayout<newFlowLayout<>>; setSize<400,400>; setLocation<400,100>; add<newJLabel<"Port:">>; port=newJTextField<"8888",25>; add<port>; start=newJButton<"Start">; add<start>; content=newJTextArea<15,35>; JScrollPanescroll=newJScrollPane<content>; add<scroll>; add<newJLabel<"Say:">>; cin=newJTextField<26>; add<cin>; say=newJButton<"Say">; add<say>; } classStartListenimplementsActionListener{ publicvoidactionPerformed<ActionEvente>{ start.setEnabled<false>; try{ ServerSockets=newServerSocket<Integer.parseInt<port.getText<>>>; socket=s.accept<>; PrintWriterout=newPrintWriter<newBufferedWriter<newOutputStreamWriter<socket.getOutputStream<>>>,true>; out.println<"连接成功">; content.append<"连接成功"+"\n">; ServerThreadst=newServerThread<>; st.start<>; } catch<Exceptionex>{ } } } classSayListenimplementsActionListener{ Stringstr; publicvoidactionPerformed<ActionEvente>{ try{ PrintWriterout=newPrintWriter<newBufferedWriter<newOutputStreamWriter<socket.getOutputStream<>>>,true>; str=cin.getText<>; if<!str.isEmpty<>>{ out.println<str>; content.append<"me:"+str+"\n">; out.flush<>; } cin.setText<"">; } catch<Exceptionex>{ } } } classServerThreadextendsThread{ publicvoidrun<>{ try{ BufferedReaderin=newBufferedReader<newInputStreamReader<socket.getInputStream<>>>; Stringstr; while<true>{ str=
