详解Java向服务端发送文件的方法

/* 
*给服务端发送文件，主要是IO流。 
*/ 
import java.io.*; 
import java.net.*; 
class send2 
{ 
  public static void main(String[] args) throws Exception 
  { 
    Socket s = new Socket("192.168.33.1",10005);//建立服务 
    BufferedReader bufr = new BufferedReader(new FileReader("io.java"));//读取IO.JAVA文件 
    PrintWriter pw = new PrintWriter(s.getOutputStream(),true);//将读到的写入服务端 
    String line = null; 
    while((line = bufr.readLine())!=null) 
    { 
      pw.println(line); 
    } 
//   pw.println("over");//标记结束位置 
    s.shutdownOutput(); 
    BufferedReader bufin = new BufferedReader(new InputStreamReader(s.getInputStream()));//读取服务端返回的数据 
    String str = bufin.readLine(); 
    System.out.println(str); 
    bufr.close(); 
    s.close(); 
  } 
}

    Socket s = ss.accept();//接收数据

    PrintWriter out = new PrintWriter(new FileWriter("io2.txt"),true);//写入到IO.TXT文本 
    String line = null; 
    while((line = bufin.readLine())!= null)//读一行写入一行

    out.close();
