Implementing a Single-Threaded Blocking Bare Bones TCP/IP Server

This article discusses the implementation of a single-threaded blocking TCP/IP server in Java. The code provided demonstrates how to create a basic server that listens on a specific port, accepts incoming client connections, reads messages from clients, and echoes them back. The server uses streams for communication, converting byte streams to character streams for text-based data exchange. The article explains the concepts of IP addresses, ports, and sockets in network communication, highlighting their roles in facilitating communication between clients and servers. Additionally, it covers the use of Telnet for testing the server's functionality and discusses the server's single-threaded blocking behavior when handling client requests sequentially. The article concludes with a demonstration of spawning multiple client threads to send concurrent connection requests to the server. Overall, it provides a comprehensive overview of building a basic TCP/IP server and understanding the underlying networking concepts involved.
