Java Server

This lesson is part of Java · All levels

Summary

Java is very popular for building server applications, ranging from simple web servers to large-scale API-based services. Java provides built-in classes like ServerSocket to understand network communication at a basic level. Modern frameworks like Spring build on these basic concepts.

Key points

ServerSocket is waiting for a connection to enter a particular port, Socket represents the connection that is formed
The basic flow of the server: open the port, accept the connection, read the request, send the response, then close it.
HTTP concepts such as the GET/POST method and status code are mandatory for web servers
Thread or ExecutorService is used to serve multiple clients at once
Production servers also pay attention to security, recording, and error handling.
