聊天程序java代码 java编一个聊天室代码和结果( 五 )

IT技术聊天


一个简单的Java多人聊天程序的代码框架如下：
服务器端：
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
public class ChatServer {
private ServerSocket serverSocket;
private ArrayListClientHandler clients;
public ChatServer(int port) throws IOException {
serverSocket = new ServerSocket(port);
clients = new ArrayListClientHandler();
System.out.println("服务器已启动，等待客户端连接...");
}
public void start() throws IOException {
while (true) {
Socket socket = serverSocket.accept();
ClientHandler client = new ClientHandler(socket, this);
clients.add(client);
client.start();
}
}
public void broadcast(String message) {
for (ClientHandler client : clients) {
client.sendMessage(message);
}
}
public void removeClient(ClientHandler client) {
clients.remove(client);
}
public static void main(String[] args) throws IOException {
ChatServer server = new ChatServer(12345);
server.start();
}
}
客户端：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
public class ChatClient {
private Socket socket;
private BufferedReader reader;
private PrintWriter writer;
private String name;
public ChatClient(String serverAddress, int port, String name) throws IOException {
socket = new Socket(serverAddress, port);
reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
writer = new PrintWriter(socket.getOutputStream(), true);
this.name = name;
}
public void start() throws IOException {
System.out.println("欢迎来到聊天室聊天程序java代码！");
new Thread(new IncomingMessageHandler()).start();
new Thread(new OutgoingMessageHandler()).start();
}
private class IncomingMessageHandler implements Runnable {
@Override
public void run() {
try {
while (true) {
String message = reader.readLine();
if (message == null) {
break;
}
System.out.println(message);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
close();
}
}
}
private class OutgoingMessageHandler implements Runnable {
@Override
public void run() {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
try {
while (true) {
String message = reader.readLine();
if (message.equals("quit")) {
break;
}
writer.println(name + ": " + message);
}
} catch (IOException e) {
e.printStackTrace聊天程序java代码；
} finally {
close();
}
}
}
要JAVA聊天程序代码，急用import java.io.InputStream;
import java.io.DataInputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.DataOutputStream;
import java.io.BufferedReader;
import java.net.ServerSocket;
import java.net.Socket;
import java.io.IOException;
import java.util.Date;
class Server
{
public Server()
{
try
{
ServerSocket s=new ServerSocket(8888);
Socket ss=s.accept();
OutputStream out=ss.getOutputStream();
DataOutputStream dout=new DataOutputStream(out);
InputStream in=ss.getInputStream();
DataInputStream din=new DataInputStream(in);
System.out.print(din.readUTF()+"!");
dout.writeUTF("你已经连接到服务器"+"\t"+"你的地址聊天程序java代码："+ss.getInetAddress()+"\t"
+"你的链接端口聊天程序java代码："+ss.getLocalPort()+"\n");
