我写了个tcp传输MP3文件的程序，请问下怎么判断传输完成了 - 黑马程序员技术交流社区

import java.io.*;

import java.net.*;

class  ReceServer

{

public static void main(String[] args) throws Exception

{

ServerSocket ss = new ServerSocket(4005);

Socket s = ss.accept();

System.out.println(s.getInetAddress().getHostAddress()+"...conection...");

BufferedInputStream bis = new  BufferedInputStream(s.getInputStream());

BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream("e:\\Music\\邓紫棋-泡沫.MP3"));

byte[] buf = new byte[1024];

int len = 0;

while ((len=bis.read(buf))!=-1)

{

bos.write(buf,0,len);

System.out.println("正在接收中");

}

BufferedWriter bufout = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

bufout.write("传输完成");

bos.close();

s.close();

ss.close();

}

}
