In 1995, a small team of engineers unveiled a new programming language designed for flexibility, portability, and robustness. That language was Java. And three decades later, it remains one of the most influential technologies in the software world.

Thank you for helping us celebrate #30YearsOfJava this past year. We look forward to many, many more years of pushing the boundaries of innovation and the pursuit of developer excellence. ❤️

Get a beginner-friendly introduction to enums in Java and learn why they’re useful in real-world programming.

We’ll break down what an enum is, how it differs from regular variables, and when you should use one in your code. https://t.co/RL0ytNsCBy

JDK 25 is the first release that includes the FFM API and has broad long-term support. Learn how this allows us to avoid the previously slow, brittle, and complex process of using JNI and ByteBuffers.

Whether you're an architect rethinking cross-platform integration or eager to conduct AI inference in Java, this #JavaOne talk is for you. https://t.co/L3tBo4z4sI

Learn how to join (concatenate) strings in Java using the + operator—one of the most basic and commonly used techniques in Java programming.

We’ll walk through simple examples to show how string concatenation works, how Java handles combining text and variables, and what happens behind the scenes when you use the + operator. https://t.co/YPVoFHJqNA

Is your tutorial still using public class HelloWorld and 50-line POJOs? You may be learning a version of Java that's a decade old.

codebysophy shows us what #Java26 actually looks like in 2026.

With JDK 27 introducing hybrid key exchange schemes that combine ML-KEM with traditional ECDHE algorithms, Java applications can gain TLS-layer protection against the _harvest-now, decrypt-later_ threat without rewriting business logic.

In this episode of the Inside Java Newscast, @ammbra1508 explains post-quantum hybrid key exchange for TLS 1.3 and demonstrates how a Java application can take advantage of it. https://t.co/c7XTbU79o0

Learn what constants are in Java and how to use them effectively in your programs. We’ll focus on the final keyword, which allows you to create variables whose values cannot be changed once assigned.

This tutorial is perfect for beginners who want to build a strong foundation in Java and write cleaner, more reliable code. 🤓 https://t.co/cburpBrFDu

In this episode of the Inside Java Newscast, @billykorando reviews the issues with how constructors used to work before Java 25—either forcing developers to write convoluted code, or in some cases undermining the safety and integrity of child classes.

He'll then cover how Flexible Constructor Bodies address these issues and how Java developers can use them to write safer code and better designed applications. https://t.co/4IUhDBXxbP

With JDK 26 and JEP 500 starting to prevent final field mutation through reflection, it's important that Java projects stop employing that practice. Whether it's for dependency injection, serialization, cloning, or general hackery, alternatives need to be explored.
