Help with Tcp problem

[oszc]

client:

import java.net.*;
import java.io.*;

public class SendFile {

	public void send()throws Exception{
		Socket socket = 
				new Socket (InetAddress.getByName("192.168.1.5"),10000);
		BufferedInputStream bis = 
				new BufferedInputStream(new FileInputStream("D:\\hello.txt"));
		BufferedOutputStream socketOut = new BufferedOutputStream(socket.getOutputStream());
		
		byte[] buff = new byte[1024];
		int len ;
		while ( (len = bis.read(buff))!=-1)
		{
			socketOut.write(buff);
		}
		System.out.println("finished");
		socket.shutdownOutput();
		BufferedReader socketInput =
				new BufferedReader( new InputStreamReader(socket.getInputStream()));
		String s = socketInput.readLine();
		System.out.println(s);
		bis.close();
		socket.close();	
	}
	
	
	public static void main(String[] args) throws Exception {
		SendFile s = new SendFile();
		s.send();
	}

}

Server:

import java.io.*;
import java.net.*;

public class ReceiveFile {
 
	public void Receive() throws Exception{
		ServerSocket serSocket = new ServerSocket(10000);
		Socket socket = serSocket.accept();
		
		BufferedOutputStream fileOut = 
				new BufferedOutputStream(new FileOutputStream("E:\\hello.txt"));
		
		BufferedInputStream inSocket = 
				new BufferedInputStream(socket.getInputStream());
		
		byte[] buf = new byte[1024];
		int len =0;
		System.out.println("Going to While");
		while ( (len = inSocket.read(buf))!=-1)   // i cant go into this loop 
		{
			System.out.println("s"+new String(buf, 0,  len));  //because this line  never printed
			fileOut.write(buf, 0, len);
			fileOut.flush();
			
		}
		String s = "finished！";
		System.out.println(s);
		DataOutputStream socketOut = new DataOutputStream(socket.getOutputStream());
		socketOut.writeBytes(s);
		
		fileOut.close();
		socket.close();
		serSocket.close();		
	}
	
	public static void main(String[] args) throws Exception {
		ReceiveFile rec = new ReceiveFile();
		rec.Receive();
	}

}

the problem was described inside the code(line 18 in the last code), can anyone help me with that?

The problem isn't in the ReceiveFile class, its in the SendFile class. You aren't reading anything out of the file so nothing is being sent to the server. Look at changing how you are trying to read characters out of the "hello.txt" file.

Edit: Sorry, misspoke. I actually tried running your example and it is reading the file, for some reason just not sending it over the stream.

Edit 2: So not actually an answer to your problem, but i've never used a BufferedOutputStream for TCP client/server. Changing

BufferedOutputStream socketOut = new BufferedOutputStream(socket.getOutputStream());

to

OutputStream socketOut = socket.getOutputStream();

immediately solves your problem.
