本文实例为大家分享了java实现TCPSocket聊天室功能的相关代码，供大家参考，具体内容如下

1.TCPserver.java

import java.net.*; import java.io.*; import java.util.*; import java.util.concurrent.*; public class TCPserver{ private static final int SERVERPORT = 8888; private ServerSocket MyServer = null; private List<Socket> Clients = new ArrayList<Socket>(); private ExecutorService mExecutorService; public TCPserver(){ try{ MyServer = new ServerSocket(SERVERPORT); mExecutorService = Executors.newCachedThreadPool(); System.out.println("start:"); Socket MySocket = null; while(true){ MySocket = MyServer.accept(); Clients.add(MySocket); mExecutorService.execute(new ThreadServer(MySocket)); } }catch(Exception e){ e.printStackTrace(); System.exit(0); } } class ThreadServer implements Runnable{ private Socket msocket=null; private BufferedReader in= null; private PrintWriter out = null; private String mStrMSG = null; public ThreadServer(Socket socket) { try{ this.msocket=socket; in = new BufferedReader(new InputStreamReader(msocket.getInputStream(), "GB2312")); mStrMSG = "user:" + msocket.getInetAddress() + " come total:" + Clients.size(); SendMassage(); }catch(IOException e){ System.out.println("erorr"); System.exit(0); } } private void SendMassage(){ try{ System.out.println(mStrMSG); for(Socket MySocket:Clients) { out = new PrintWriter(new OutputStreamWriter(MySocket.getOutputStream(),"GB2312"),true); out.println(mStrMSG); } }catch(IOException e){ System.out.println("erorr"); System.exit(0); } } public void run(){ try{ while((mStrMSG = in.readLine())!=null){ if(mStrMSG.trim().equals("exit")){ Clients.remove(msocket); in.close(); out.close(); mStrMSG = "user:" + msocket.getInetAddress() + " exit tatal:" + Clients.size(); ; msocket.close(); SendMassage(); break; } else{ mStrMSG = msocket.getInetAddress()+":" + mStrMSG; SendMassage(); } } }catch(IOException e){ System.out.println("erorr"); System.exit(0); } } } public static void main(String[] args){ new TCPserver(); } }

2.TCPclient.java

import java.net.*; import java.io.*; import java.util.concurrent.*; public class TCPclient { private static final int PORT = 8888; private Socket Client = null; private BufferedReader sin = null; private ExecutorService mExecutorService; public TCPclient(){ try{ Client = new Socket("120.27.126.174",PORT); sin = new BufferedReader(new InputStreamReader(Client.getInputStream(),"GB2312")); mExecutorService = Executors.newCachedThreadPool(); mExecutorService.execute(new ThreadClient(Client)); String msg = null; while((msg = sin.readLine()) != null) { System.out.println(msg); } }catch(IOException e){ System.out.println(e.getMessage()); } } class ThreadClient extends Thread{ private Socket mSocket = null; private String msg = null; BufferedReader in = null; PrintWriter out = null; public ThreadClient(Socket socket){ this.mSocket = socket; } public void run(){ try{ in = new BufferedReader(new InputStreamReader(System.in)); out = new PrintWriter(new OutputStreamWriter(mSocket.getOutputStream(), "GB2312"), true); while(true){ msg = in.readLine(); out.println(msg); if(msg.trim().equals("exit")){ in.close(); out.close(); mExecutorService.shutdownNow(); break; } } }catch(IOException e){ System.out.println("see you"); System.exit(0); } } } public static void main(String[] args){ new TCPclient(); } }

以上就是java实现TCPSocket聊天室功能的代码，希望对大家的学习有所帮助。
