Java网络编程(TCP协议-练习-上传文本文件)

客户端：

 package WebProgramingDemo;

 import java.io.BufferedReader;

 public class UploadTextClient {

     /**
      * @param args
      * @throws IOException
      * @throws UnknownHostException
      */
     public static void main(String[] args) throws UnknownHostException,
             IOException {

         Socket s = new Socket("192.168.2.103", 10005);
         BufferedReader bufr = new BufferedReader(new FileReader("client.txt"));
         PrintWriter out = new PrintWriter(s.getOutputStream(), true);
         String line = null;
         while ((line = bufr.readLine()) != null) {
             out.println(line);

         }
         s.shutdownOutput();
         BufferedReader bufIn = new BufferedReader(new InputStreamReader(
                 s.getInputStream()));
         String str = bufIn.readLine();
         System.out.println(str);
         bufr.close();
         s.close();

     }

 }
