Project Valhalla is changing how Java works. For years, Java has been safe and easy to use. But it often uses more memory than needed. That slowed down apps that process lots of data. This project is part of the OpenJDK. Its goal is to make Java faster and leaner. New tools like value types, inline classes, and generic specialization …
Post-Quantum Cryptography Support in Java
Quantum computers are advancing, and they could soon break the encryption that protects todayโs data. RSA and ECC, which are standard today, may not stand up to quantum attacks. This makes post-quantum cryptography a key part of planning for long-term security. Java is already preparing for this future. New updates in the JDK add support for quantum-safe algorithms, giving developers …
Whatโs New in Java 25 (LTS): Language, APIs, and Runtime Performance
Every new Java release impacts how teams build and run their applications. Java 25 arrived in September 2025 as the next long-term support (LTS) version after Java 21. It adds features that cut boilerplate, enhance security, and speed up code performance. Now is the perfect time to get familiar with updates and lay the groundwork for modernization efforts later down the line.
Below, we explain the main updates. We cover syntax, APIs, and runtime gains that can help teams save time and boost performance.
Spring AI: An Overview
Integrating AI into Java projects has traditionally been complexโrequiring multiple SDKs, custom integrations, and provider-specific code. Spring AI simplifies this process by providing a single, consistent layer for working with large language models in Spring Boot. No more stitching together libraries or rewriting code for every provider. In this guide, weโll explore what Spring AI is, why it matters for …
Writing Java Code and Unit Tests Faster with GitHub Copilot
In this post, weโll explore how to use GitHub Copilot to generate Java code and unit tests with minimal manual input. Using a real-world exampleโa mortgage calculator serviceโyouโll see how Copilot can help write both the core logic and the corresponding unit tests. Whether youโre new to AI-assisted development or curious about Copilotโs capabilities in a Java environment, this tutorial will give you practical insight into how it worksโand where human oversight still matters.
