Concurrent ServerSocket connections

Question

Refer this post in Andrey Kozhanov' code.

In Server.java, line 14, method run():

When I send a file "A" and during file transfer start another Client and send other file "B", this last transfer ("B") will block until "A" finishes.

How can I implement a concurrent server receiver?

Thanks.

You can create new Thread for every new client.

public class Server extends Thread {

     ...

    @Override
    public void run() {
        try {
            ServerSocket serverSocket = new ServerSocket(PORT);

            while (true) {
                Socket s = serverSocket.accept();
                (new FileSaver(s)).start();

            }
         } catch (Exception e) {
            e.printStackTrace();
         }
     }

    ...
}

public class FileSaver extends Thread {

    Socket socket;

    public FileSaver(Socket socket) {
        socket = socket;
    }

    public saveFile() {
        // save the file here
    };

    public void run() {
        saveFile();
    }

}
