利用socket套接字实现简易聊天室，下面是简易的安卓客户端和电脑实现交互，

实现界面：

客户端：

服务器端：

代码如下

服务器端MySocketServer.Java：（服务器端新建一个javaProject）

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class MySocketServer {

   public static void main(String[] args)throws IOException{

       ServerSocket serversocket=new ServerSocket(30000);

       System.out.println("=======连接成功========");
       while(true){

           final Socket socket=serversocket.accept();
           Thread t=new Thread(new Runnable(){

               public void run() {
                   // TODO Auto-generated method stub
                   try {
                       InputStream input=socket.getInputStream();
                       OutputStream output=socket.getOutputStream();
                       BufferedReader buff=new BufferedReader(new InputStreamReader(input));
                       output.write("服务器:小朋友，你好呀！".getBytes("UTF-8"));
                       output.flush();
                       socket.shutdownOutput();
                       String line="";
                       while((line=buff.readLine())!=null){
                           System.out.println(line);
                       }
                       output.close();
                       input.close();
                       buff.close();
                       socket.close();
                   } catch (IOException e) {
                       // TODO Auto-generated catch block
                       e.printStackTrace();
                   }

               }

           });
           t.start();
       }
   }
}
