本文實例為大家分享了Java Socket聊天室功能的具體代碼，供大家參考，具體內容如下
Client.java
import java.io.*;
import java.net.*;
import java.util.*;
public class Client {
public int port = 8083;
Socket socket = null;
public static void main(String[] args) {
new Client(); //開始執行
}
public Client() {
try {
socket = new Socket("127.0.0.1", port);
new Cthread().start();
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String msg1;
while ((msg1 = br.readLine()) != null) {
System.out.println(msg1);
}
} catch (Exception e) {
}
}
class Cthread extends Thread {
public void run() {
try {
BufferedReader re = new BufferedReader(new InputStreamReader(System.in));
PrintWriter pw = new PrintWriter(socket.getOutputStream(), true);
String msg2;
while (true) {
msg2 = re.readLine();
pw.println(msg2);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Server.java
import java.net.*;
import java.io.*;
import java.util.*;
public class Server {
int port;
List clients;
ServerSocket server;
public Server() {
try {
port = 8083;
clients = new ArrayList();
server = new ServerSocket(port);
System.out.println("服務器已啟動");
int co=1;
while (true) {
Socket socket = server.accept();
clients.add(socket);
Mythread mythread = new Mythread(socket,co);
co++;
mythread.start();
}
} catch (Exception ex) {
System.out.println("vv");
}
}
public static void main(String[] args) {
new Server();
}
class Mythread extends Thread {
Socket ssocket;
private int count;
private BufferedReader br;
private PrintWriter pw;
public String msg;
public Mythread(Socket s,int c) {
ssocket = s;
count=c;
}
public void run() {
try {
br = new BufferedReader(new InputStreamReader(ssocket.getInputStream()));
msg = "歡迎【" +"Client "+count + "】進入聊天室！當前聊天室有【" + clients.size() + "】人";
sendMsg();
while ((msg = br.readLine()) != null) {
msg = "【" +"Client "+count + "】說：" + msg;
sendMsg();
}
} catch (Exception ex) {
}
}
public void sendMsg() {
try {
System.out.println(msg);
for (int i = clients.size() - 1; i >= 0; i--) {
pw = new PrintWriter(clients.get(i).getOutputStream(), true);
pw.println(msg);
pw.flush();
}
} catch (Exception ex) {
}
}
}
}
