最全面的基于TCP/IP的FTP服务器端要和我上传的客户端一起使用，还有聊天的功能，java程序代码，多线程设计，我花了将近二个月的时间-the most comprehensive TCP / IP-based FTP server to upload and my client used together, chat functions, java code, multithreaded design, I spent nearly two months of the time

This program demonstrates a simple TCP/IP server. It will accept a connection from a client application, receive one line of text, echo that line back to the client and close the connection.
