问题如下，求高手解答，谢谢

代码如下：

//并发图片上传
import java.io.*;
import java.net.*;

class PicClient2
{
public static void main(String[] args) throws Exception
{
Socket s = new Socket(InetAddress.getByName("localhost"),11111);

    BufferedInputStream bufis = new BufferedInputStream(new FileInputStream("E:\\nz.jpg"));

    byte[] data = new byte[1024*1024*5];
    int len = bufis.read(data);

    OutputStream out = s.getOutputStream();
    InputStream in = s.getInputStream();

    out.write(data,0,len);
    out.flush();

    len = in.read(data);
    String show = new String(data,0,len);
    System.out.println(show);

    bufis.close();
    s.close();
}

}

class PicServer2
{
public static void main(String[] args) throws Exception
{
ServerSocket ss = new ServerSocket(11111);

    Socket s = ss.accept();

    PrintStream ps = new PrintStream(new FileOutputStream("D:\\nzz.jpg"),true);

    InputStream in = s.getInputStream();
    byte[] data = new byte[1024*1024*5];
    int len = in.read(data);

    ps.write(data,0,len);
    ps.flush();

    OutputStream out = s.getOutputStream();
    out.write("上传成功".getBytes());
    out.flush();

    ps.close();
    s.close();
    ss.close();
}   

}
