接触到了网络，跟着做了一次，瞬间感觉高大上了很多，不过还是很基础的东西。

服务器端：

/** * Function:服务器端 *  * Author:Jz_xy * Date:2014.12.09 */package com.test1;import javax.swing.*;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.io.*;import java.net.*;public class MyServer3 extends JFrame implements ActionListener{JTextArea jta = null;JTextField jtf = null;JButton jb = null;JScrollPane jsp = null;JPanel jp1 = null;//把信息发给客户端的对象PrintWriter pw = null;public static void main(String[] args) {// TODO Auto-generated method stubMyServer3 ms3 = new MyServer3();}public MyServer3(){jta = new JTextArea();jsp = new JScrollPane(jta);jtf = new JTextField(20);jb = new JButton("发送");jb.addActionListener(this);jp1 = new JPanel();jp1.add(jtf);jp1.add(jb);this.add(jsp,"Center");this.add(jp1,"South");this.setSize(400,300);this.setTitle("QQ聊天，服务器端");this.setVisible(true);this.setDefaultCloseOperation(EXIT_ON_CLOSE);try {//服务器监听ServerSocket ss = new ServerSocket(9988);//等待连接Socket s = ss.accept();InputStreamReader isr = new InputStreamReader(s.getInputStream());BufferedReader br = new BufferedReader(isr);pw = new PrintWriter(s.getOutputStream(),true);//读取从客户端发来的信息while(true){//读取送客户端发来的信息String infoFromClient = br.readLine();jta.append("客户端 对 服务器 说： " + infoFromClient + "\r\n");}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stub//如果用户按下发送信息的按钮if(e.getSource() == jb){//把服务器在jtf中的信息，发送给客户端String info = jtf.getText();//把服务器发送的信息先是到jtajta.append("服务器 对 客户端 说： " + info + "\r\n");pw.println(info);//清空jtfjtf.setText("");}}}

客户端：

/** * Function:这是一个客户端 *  * Author:Jz_xy * Date:2014.12.09 */package com.test1;import javax.swing.*;import java.net.*;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.io.*;public class MyClient3 extends JFrame implements ActionListener{JTextArea jta = null;JTextField jtf = null;JButton jb = null;JScrollPane jsp = null;JPanel jp1 = null;PrintWriter pw = null;public static void main(String[] args) {// TODO Auto-generated method stubMyClient3 ms3 = new MyClient3();}public MyClient3(){jta = new JTextArea();jsp = new JScrollPane(jta);jtf = new JTextField(20);jb = new JButton("发送");jb.addActionListener(this);jp1 = new JPanel();jp1.add(jtf);jp1.add(jb);this.add(jsp,"Center");this.add(jp1,"South");this.setSize(400,300);this.setTitle("QQ聊天，客户端");this.setVisible(true);this.setDefaultCloseOperation(EXIT_ON_CLOSE);try {Socket s = new Socket("127.0.0.1",9988);InputStreamReader isr = new InputStreamReader(s.getInputStream());BufferedReader br = new BufferedReader(isr);pw = new PrintWriter(s.getOutputStream(),true);while(true){//不停地读取从服务器端发来的信息String info = br.readLine();jta.append("服务器 对 客户端 说： " + info + "\r\n");}} catch (Exception e) {// TODO: handle exceptione.printStackTrace();}}@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubif(e.getSource() == jb){String info = jtf.getText();//把客户端发送的信息先是到jtajta.append("客户端 对 服务器 说： " + info + "\r\n");pw.println(info);jtf.setText("");}}}
