服务器端程序：

package yx.socket;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;public class Server {public static void main(String[] args) {ServerSocket ss=null;Socket s=null;String message="";try {ss = new ServerSocket(9999);s=ss.accept();String ip=s.getInetAddress().getHostAddress();InputStream in=s.getInputStream();byte[] buffer=new byte[1024];int len=0;while((len=in.read(buffer))!=-1){message+=new String(buffer,0,len);}System.out.println("服务器收到指令："+message);OutputStream out=s.getOutputStream();out.write(message.getBytes());System.out.println("服务器发出指令："+message);} catch (IOException e) {e.printStackTrace();}finally{try {if(s!=null)s.close();if(ss!=null)ss.close();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}

客户端程序

package yx.socket;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;public class Client {public static void main(String[] args) {Socket s=null;String message="哥哥，我来了！！！";try {s=new Socket("127.0.0.1", 9999);OutputStream out=s.getOutputStream();out.write(message.getBytes());System.out.println("客户端发送指令："+message);InputStream in=s.getInputStream();byte[] buffer=new byte[1024];int len=0;while((len=in.read(buffer))!=-1){message+=new String(buffer,0,len);}System.out.println("客户端接受指令："+message);}catch (Exception e) {e.printStackTrace();}}}
