Cryptography is an essential pillar of modern software development. With rising concerns around privacy, data breaches, and secure communications, it has become increasingly important to use fast, reliable, and secure encryption algorithms.In Java 11, two powerful cryptographic algorithms — ChaCha20 and Poly1305 — were officially introduced. These algorithms provide developers with the ability to perform

Modern software systems, especially those built with Java, are often deployed in complex, dynamic environments where performance monitoring and troubleshooting are critical. Over the years, the Java ecosystem has evolved various tools to assist developers and system administrators in diagnosing performance issues with minimal impact on running applications. One of the most significant advancements in

Java Flight Recorder (JFR) is an integrated profiling and diagnostics tool in the Java Virtual Machine (JVM), designed to monitor and analyze Java applications with minimal performance impact. With Java 11, JFR became open-sourced in OpenJDK, eliminating the need for commercial licenses and making it widely accessible for developers. This essay briefly explores JFR’s significance,
Java 11 introduced the standardized HTTP Client API (module java.net.http, package java.net.http) as part of JEP 321, replacing the legacy HttpURLConnection with a modern, flexible, and feature-rich API. It supports HTTP/1.1, HTTP/2, WebSocket, and both synchronous and asynchronous requests, eliminating the need for third-party libraries like Apache HttpClient for many use cases. Below is a
Java 11 introduced six new methods to the String class to enhance string manipulation, particularly with better Unicode support and streamlined operations. isBlank() Purpose: Returns true if the string is empty or contains only whitespace characters (including Unicode whitespace), otherwise false. Use Case: Useful for validating input strings to check if they are effectively empty.
