如何用Java编写一个聊天室程序 ， 可以支持单聊和多聊？聊天程序又叫即时通讯系统
分类两部分：客户端和服务端
客户端：用户聊天用java编写聊天室代码的界面
服务端：接收消息并转发到指定用户
其中服务端和客户端用tcp或者udp连接用java编写聊天室代码，使用socket编程完成通信 。
按着这个思路可以开发出一套聊天程序
客户端常用界面 bs版本的又layim
服务端 openfire或者自己实现

java实现聊天室是怎么做到的？Java 实现聊天室可以分为以下几个步骤：
建立服务器端
首先需要建立一个服务器端，负责接收客户端的连接请求并处理客户端发送过来的消息 。
建立客户端
然后需要建立客户端，客户端通过网络连接到服务器端，并向服务器端发送消息 。
实现通信协议
为了实现聊天室功能，需要定义一个通信协议，规定客户端和服务器端之间的通信格式，例如消息的头部和内容等 。
实现多线程处理
聊天室通常会有多个用户同时在线，因此需要使用多线程来处理多个客户端的连接请求和消息传递 。
实现GUI界面（可?。?
为了方便用户使用，可以实现一个GUI界面，让用户可以方便地发送和接收消息 。
以下是一个简单的 Java 聊天室的代码示例：
java
Copy code
// 服务器端代码
public class Server {
public static void main(String[] args) {
try {
ServerSocket serverSocket = new ServerSocket(8888);
while (true) {
Socket socket = serverSocket.accept();
new Thread(new ServerThread(socket)).start();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
class ServerThread implements Runnable {
private Socket socket;
private BufferedReader reader;
private PrintWriter writer;
public ServerThread(Socket socket) {
this.socket = socket;
try {
reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
writer = new PrintWriter(socket.getOutputStream());
} catch (IOException e) {
e.printStackTrace();
}
}
public void run() {
try {
String msg;
while ((msg = reader.readLine()) != null) {
// 处理客户端发送过来的消息
System.out.println("接收到消息："msg);
// 将消息发送给所有客户端
for (Socket s : ServerThreadList.getList()) {
if (s != socket) {
PrintWriter w = new PrintWriter(s.getOutputStream());
w.println(msg);
w.flush();
}
}
}
// 关闭连接
socket.close();
ServerThreadList.removeThread(this);
} catch (IOException e) {
e.printStackTrace();
}
}
}
class ServerThreadList {
private static List
list = new ArrayList();
public static void addThread(ServerThread thread) {
list.add(thread);
}
public static void removeThread(ServerThread thread) {
list.remove(thread);
}
public static List
getList() {
return list;
}
}
// 客户端代码
public class Client {
public static void main(String[] args) {
try {
Socket socket = new Socket("localhost", 8888);
new Thread(new ClientThread(socket)).start();
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
PrintWriter writer = new PrintWriter(socket.getOutputStream());
while (true) {
String msg = reader.readLine();
writer.println(msg);
writer.flush();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
class ClientThread implements Runnable {
private Socket socket;
private BufferedReader reader;
public ClientThread(Socket socket) {
this.socket = socket;
try {
reader
java简易聊天室用java编写聊天室代码你要用java编写聊天室代码的就是点对点通信用java编写聊天室代码，见以下例子用java编写聊天室代码：
1.简单服务器端
/*
import java.net.*;
import java.io.*;
*/
ServerSocket server=null;
try {
server=new ServerSocket(%%1);
}catch(Exception e){
System.out.println("不能监听:" e.toString());
}
Socket socket=null;
try {
socket=server.accept();
BufferedReader %%3=new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter %%4=new PrintWriter(socket.getOutputStream());
String %%2=%%3.readLine();
%%4.println("");
%%4.flush();
%%4.close();
%%3.close();
}
catch(IOException e){
System.out.println("出错:" e.toString());
}finally{
try {
if(socket!=null){
socket.close();
server.close();
}
}
catch(IOException e){
e.printStackTrace();
}
}
2.简单客户端
/*
import java.net.*;
import java.io.*;
*/
Socket socket=null;
try {
socket=new Socket(%%1,%%2);
PrintWriter %%3=new PrintWriter(socket.getOutputStream());
BufferedReader %%4 = new BufferedReader(new InputStreamReader(socket.getInputStream()));
%%3.println("");
%%3.flush();
String %%5=%%4.readLine();
%%6
%%3.close();
%%4.close();
}catch(Exception e){
e.printStackTrace();
}
finally{
try {
socket.close();
}
catch(IOException e){
e.printStackTrace();
}
}
3.获得本机IP
//import java.net.*;
String strIP = null;
try
{
strIP =InetAddress.getLocalHost().getHostAddress().toString();
}
catch(UnknownHostException e)
{
e.printStackTrace();
}
/*
%%1=InetAddress.getLocalHost().getHostAddress();
EnumerationNetworkInterface netInterfaces = null;
try {
netInterfaces = NetworkInterface.getNetworkInterfaces();
while (netInterfaces.hasMoreElements()) {
NetworkInterface ni = netInterfaces.nextElement();
System.out.println("DisplayName:"ni.getDisplayName());
System.out.println("Name:"ni.getName());
EnumerationInetAddress ips = ni.getInetAddresses();
while (ips.hasMoreElements()) {
System.out.println("IP:"
ips.nextElement().getHostAddress());
}
}
} catch (Exception e) {
e.printStackTrace();
}
*/
5.点对点通信
/*
import java.io.*;
import java.net.*;
*/
public class %%6 extends Thread {
@Override
public void run() {
ServerSocket server = null;
try {
server = new ServerSocket(5000);
} catch (Exception e) {
System.out.println("不能监听:"e.toString());
}
Socket socket = null;
try {
socket = server.accept();
BufferedReader req = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
PrintWriter os = new PrintWriter(socket.getOutputStream());
Debug.p(req.readLine());
os.println("Server");
os.flush();
os.close();
req.close();
} catch (IOException e) {
System.out.println("出错:"e.toString());
} finally {
try {
if (socket != null) {
socket.close();
server.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
Thread t = new %%6();
t.start();
String strIP = null;
try {
strIP = InetAddress.getLocalHost().getHostAddress().toString();
} catch (UnknownHostException e) {
e.printStackTrace();
}
Socket socket = null;
try {
socket = new Socket(strIP, 4000);
PrintWriter pw = new PrintWriter(socket.getOutputStream());
BufferedReader br = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
pw.println("Client");
pw.flush();
Debug.p(br.readLine());
pw.close();
br.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
