About the Book

Java in 2026 isn't the Java you remember. Records, sealed classes, pattern matching, virtual threads, and structured concurrency are now standard, and the platform runs everywhere from cloud microservices to embedded controllers. Java Programming in 2026 is a thorough, hands on introduction to modern Java, written specifically for professional software engineers who already know another language, such as Python, JavaScript, C#, Go, Rust, or Kotlin, and want to get productive fast with Java 25, the current long term support release.


This isn't a book for people who need loops and lists explained. It assumes general programming literacy and moves quickly from language fundamentals into the territory that's specifically Java: the type system and generics, object oriented design, error handling, the Collections and Streams APIs, concurrency with virtual threads, the modern standard library, testing and tooling, building REST services, and project structure with Maven and Gradle.

Every chapter contains complete, runnable examples with annotated explanations, all tested on Java 25. Rather than covering the entire sprawling Java ecosystem, the book focuses tightly on the idioms, build tools, and ecosystem decisions that professional Java teams actually rely on today, so you finish ready to read, write, and ship Java with confidence.

About the Author

SouthStone Publications

The founder of SouthStone Publications draws on more than twenty years in IT and cybersecurity, bringing that depth of experience into everything he writes. At heart, he's a technologist through and through: part enthusiast, part researcher, part engineer, part technical leader, having grown up alongside the internet itself and evolved right along with it.

His career sits at the crossroads of system design and cybersecurity, approached from both the offensive and defensive sides of the discipline. Over the years, he has built a reputation for turning complex, often intangible technical knowledge into practical guidance that professionals can actually put to work.

He currently serves on the leaderships in engineering and cybersecurity team at a leading IT services company in its industry, where he relentless studies emerging AI technologies and also cyber threats while helping organizations navigate the risks already at their doorstep. His expertise spans an unusually wide range of disciplines, consists of security engineering and development, project management, application security, infrastructure security, vulnerability management, reverse engineering, penetration testing, security architecture, incident response, and threat hunting and intelligence. He is equally at home diagnosing a flawed system architecture from the ground up, dissecting a sophisticated piece of malware, or leading red team operations against live threats - moving fluidly between granular technical detail and big-picture strategy in a way that few in the field can match.

Besides his astounding professional career experiences, he has partners with subject matter experts with backgrounds in technical writing, focused on AI, IT and security education, producing technical books and training programs that have helped countless developers, analysts, and practitioners build more resilient systems. That same dedication to clarity, rigor, and real-world relevance defines his work with SouthStone Publications, where deep technical expertise meets a mission to make security knowledge accessible, actionable, and built to be sustainable, lasting and progressive. SouthStone Publications is the first publisher of Cybersecurity category books in LeanPub.
