Mastering Modern Concurrency in Java - A Comprehensive Deep Dive with Virtual Threads
Traditional methods of handling multiple tasks in Java have limitations, such as resource-heavy threads and complex code. These limitations can hinder performance and development speed in today's world, where fast, efficient applications are a must.
This session aims to introduce and demystify the latest Java 21 concurrency features—Virtual Threads, Structured Concurrency, Scoped Values. These tools can help you build faster, more efficient applications while keeping your code clean and manageable.
We'll deep-dive into each of these four topics through a blend of theory and practical code examples. You'll learn how to:
- Utilize Virtual Threads for efficient multitasking
- Implement Structured Concurrency for more readable and maintainable code
- Leverage Scoped Values for smarter data sharing
- Understand the continued relevance of Reactive Java in this new landscape
Whether you're a seasoned developer or an architect, this session will equip you with the knowledge and skills to implement these modern features effectively.
Join me and take the first step towards mastering the future of Java concurrency!
Just Pattern Matching: Java Catches Up (But Is It Enough?)
Ready to ditch those tangled if-else chains and say goodbye to clumsy type checks? Java's new pattern-matching features promise a cleaner, more elegant way to code. But can they truly match the power and expressiveness that Kotlin and Scala developers have enjoyed for years? This talk takes a deep dive into Java's pattern-matching evolution, comparing its capabilities side-by-side with these JVM heavyweights. Discover where Java excels, where it might still fall short, and whether it's time to refactor your projects confidently.
Whether you're a Java loyalist, a Kotlin convert, or a Scala enthusiast, you'll leave with a fresh perspective on the pattern-matching landscape.
From Blocking to Breakthrough: A Tale of Java's Scalability Journey
Writing blocking code might seem effortless, but it comes at the cost of application responsiveness and scalability. Non-blocking code offers a path to greater efficiency and throughput. In this session, we'll chart the evolution of Java's concurrency model, exploring the trade-offs and techniques that make non-blocking development possible.
We'll start with the classic thread model, delve into Futures/Callables and CompletableFutures, touch on the power of reactive programming, and culminate with the game-changing potential of Project Loom.
Come away equipped to make informed choices about when and how to harness non-blocking code for your Java projects.
Breaking Java Stereotypes: It's Not Your Dad's Language Anymore
Discover the transformed Java programming language that defies stereotypes and embraces modernity. Explore its evolution with features like Records, Pattern Matching, Sealed Classes, Functional Programming, Virtual Threads, Structured Concurrency, String Templates, Flexible Main Method, Text Blocks, and Data-Oriented Programming. Learn how these advancements empower developers to write concise, expressive, and efficient code, dispelling the notion that Java is a legacy language. Join us to break the Java stereotypes and embrace the exciting possibilities of this dynamic and forward-thinking language.
Breaking Barriers: Virtual Threads Transforming Java’s Framework Landscape
In the evolving landscape of concurrent programming in Java, the introduction of virtual threads, part of Project Loom, marks a significant shift. This talk explores the practical applications and performance implications of virtual threads in popular Java frameworks like Spring Boot, Quarkus, Vert.x, Micronaut, and Helidon. By comparing and contrasting their integration and optimization with virtual threads, the session will provide attendees with a comprehensive understanding of leveraging this technology in different frameworks to achieve scalable and efficient applications.
A tale of two cities: blocking code vs. non-blocking code
We don’t have to exert much mental effort when writing blocking code, but this has drawbacks. Non-blocking code, on the other hand, could be used to increase application throughput. This is why non-blocking code is recommended in many scenarios. Over the last two decades, many approaches have been introduced to writing code that does not block.
In this session, we will look into those options that are available to us. To begin, I’ll go over the evolution of the Java concurrency model since its inception with the vanilla thread. Then I will introduce Future/Callable, and CompletableFuture, briefly go over reactive programming, and finally conclude with the Project Loom that was added in Java 19.
Breaking Java Stereotypes: It's Not Your Dad's Language Anymore
Forget what you thought you knew about Java. This isn't the clunky language of yesteryear. With a wave of powerful new features, Java has shed its verbose reputation and emerged as a streamlined, expressive force in modern development.
In this talk, we'll dive into the Java renaissance. Explore records, sealed classes, pattern matching, and string templates – the tools that are making Java code more concise and elegant than ever before. We'll also take a peek at virtual threads and structured concurrency, features that streamline multithreading for the modern era.
