I am programming a server and a client, the client will send a file to the server, however, I need to send the file name together, so that the server recognizes and write the file with the name sent by the client. Currently it does not send the file name, so I must inform the server of the file name and its path where it will be saved.
Is it possible to send the file name and path that will be saved to the file?
And if it is possible, what code snippet should I use to be able to point out such information?
If Anyone can help me, I really appreciate it.



client side



public class FileSenderClient 
private void sendFile(SocketChannel socketChannel) throws IOException
Path path = Paths.get("C:\SIS\database.FDB");\ path to file
FileChannel inChannel = FileChannel.open(path);

while (inChannel.read(buffer) > 0)
buffer.flip();
socketChannel.write(buffer);

  • There are dozens of ways to do this. However, they all require you to have a good grip on "Java Sockets". Judging from the way you posed your question, most of this code is copied and pasted from somewhere else, making it hard for you to understand the basic mechanism on which your server works.
