提示：以下是本篇文章正文内容，下面案例可供参考

一、聊天室功能介绍？

1. 、对于聊天室就是处理多个客户端发送的请求与信息，从而需要一个服务器端去处理这些客户端请求与信息，故采用的是服务器端/客户端模式（本章只讲解一个客户端与服务端的交流）。
2. 客户端与服务器端的连接：既然是多个客户端发送的请求与信息从而交给服务器端处理，那么客户端与服务器端之间需要进行连接。稍后会通过分析以及代码的方式进行详细操作

3. 客户端方面：客户端在与服务器端建立连接后，通过Socket对象获取输入输出流从而与服务器端之间进行通信。
4. 服务器端方面：服务器端的套接字ServerSocket对象在调用accept()方法侦听客户端的连接，当与客户端成功建立连接后，返回Socket对象，从而利用该Socket对象获取输入输出流从而与客户端进行通信。

二、功能代码

1.服务端

代码如下（示例）：

package wdw;import java.awt.BorderLayout;import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.text.SimpleDateFormat;
import java.util.Date;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.UIManager;public class Fwd_UI extends JFrame implements ActionListener,KeyListener {public static void main(String[] args)throws Exception {
//		设置界面的方格与系统相似（须在窗体加载之前）
//		UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");UIManager.setLookAndFeel("org.jb2011.lnf.beautyeye.BeautyEyeLookAndFeelCross");new Fwd_UI();}private JTextArea jta;private JScrollPane jsp;private JPanel jp;private JTextField jtf;private JButton jb;private BufferedWriter bh=null;public Fwd_UI() {jta=new JTextArea();jta.setEditable(false);jsp=new JScrollPane(jta);jp=new JPanel();jtf=new JTextField(10);jb=new JButton("发送");jp.add(jtf);jp.add(jb);this.add(jsp,BorderLayout.CENTER);this.add(jp,BorderLayout.SOUTH);this.setTitle("星泽聊天服务端");this.setSize(300,300);this.setLocation(500, 300);this.setLocationRelativeTo(null);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setVisible(true);jb.addActionListener(this);jtf.addKeyListener(this);try {ServerSocket ServerSocket=new ServerSocket(8888);Socket Socket=ServerSocket.accept();
//			InputStream in=Socket.getInputStream();BufferedReader br=new BufferedReader(new InputStreamReader(Socket.getInputStream()));bh= new BufferedWriter(new OutputStreamWriter(Socket.getOutputStream()));String line=null;Date sb=new Date();SimpleDateFormat sdf = new SimpleDateFormat();sdf.format(sb);jta.append("\t"+sdf.format(sb)+"\n");while ((line=br.readLine())!=null) {jta.append(line+System.lineSeparator());}Socket.close();} catch (Exception e) {e.printStackTrace();}}@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubwdw();}//定义一个方法private void wdw() {String text=jtf.getText();text="服务端对客户端说："+text;jta.append(text+System.lineSeparator());try {bh.write(text);bh.newLine();bh.flush();jtf.setText("");} catch (IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}}@Overridepublic void keyPressed(KeyEvent e) {// TODO Auto-generated method stubif (e.getKeyCode()==KeyEvent.VK_ENTER) {wdw();}}@Overridepublic void keyTyped(KeyEvent e) {// TODO Auto-generated method stub}@Overridepublic void keyReleased(KeyEvent e) {// TODO Auto-generated method stub}}

2.客户端

代码如下（示例）：

package wdw;import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.text.SimpleDateFormat;
import java.util.Date;import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
import javax.swing.UIManager;public class Khf_UI extends JFrame implements ActionListener,KeyListener {public static void main(String[] args)throws Exception {
//		设置界面的方格与系统相似（须在窗体加载之前）
//		UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");UIManager.setLookAndFeel("org.jb2011.lnf.beautyeye.BeautyEyeLookAndFeelCross");new Khf_UI();}private JTextArea jta;private JScrollPane jsp;private JPanel jp;private JTextField jtf;private JButton jb;private BufferedWriter bh=null;public Khf_UI() {jta=new JTextArea();jta.setEditable(false);jsp=new JScrollPane(jta);jp=new JPanel();jtf=new JTextField(10);jb=new JButton("发送");jp.add(jtf);jp.add(jb);this.add(jsp,BorderLayout.CENTER);this.add(jp,BorderLayout.SOUTH);this.setTitle("星泽聊天客户端");this.setSize(300,300);this.setLocation(500, 300);this.setLocationRelativeTo(null);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setVisible(true);jb.addActionListener(this);jtf.addKeyListener(this);try {Socket Socket=new Socket("127.0.0.1", 8888);//			InputStream in=Socket.getInputStream();BufferedReader br=new BufferedReader(new InputStreamReader(Socket.getInputStream()));bh= new BufferedWriter(new OutputStreamWriter(Socket.getOutputStream()));String line=null;Date sb=new Date();SimpleDateFormat sdf = new SimpleDateFormat();sdf.format(sb);jta.append("\t"+sdf.format(sb)+"\n");while ((line=br.readLine())!=null) {jta.append(line+System.lineSeparator());}Socket.close();} catch (Exception e) {e.printStackTrace();}}@Overridepublic void actionPerformed(ActionEvent e) {// TODO Auto-generated method stubwdw();}//定义一个方法private void wdw() {String text=jtf.getText();text="客户端对服务端说："+text;jta.append(text+System.lineSeparator());try {bh.write(text);bh.newLine();bh.flush();jtf.setText("");} catch (IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}}@Overridepublic void keyPressed(KeyEvent e) {// TODO Auto-generated method stubif (e.getKeyCode()==KeyEvent.VK_ENTER) {wdw();}}@Overridepublic void keyTyped(KeyEvent e) {// TODO Auto-generated method stub}@Overridepublic void keyReleased(KeyEvent e) {// TODO Auto-generated method stub}}

该处使用的界面美化包，需要导包。
