This is a very good time to look at what was released in the JDK 21, and what is currently been developed, and could be released in 25. Structured Concurrency is almost there, Data Oriented Programming is taking shape, so we now have a good idea of what it will bring for us, developers. This presentation covers four of the projects currently been developed by the OpenJDK. First, we will take a quick look at Panama, that released the Foreign Function and Memory API and Valhalla and that is still developing value types and non-nullable types, as well as the Vector API. Then, we will spend some time on Loom, that delivered Virtual Threads, and is still developing Structured Concurrency, to understand why you will need this feature once they are made final. And lastly, we will present Amber, how it implements the Data Oriented Programming paradigm to the Java platform, and how you can leverage this programming model to write better applications, organized in a better way and easier to maintain. jcconf-2024-55227-java-21-and-beyond-state-of-loom-and-amber 401 Jose PAUMARD zh-hant false slide https://pretalx.com/jcconf-2024/talk/F39GPS/ https://pretalx.com/jcconf-2024/talk/F39GPS/feedback/ 401 Session 2024-09-27T10:25:00+08:00 10:25 00:10 - jcconf-2024-55228-break zh-hant false https://pretalx.com/jcconf-2024/talk/NJ3TET/ https://pretalx.com/jcconf-2024/talk/NJ3TET/feedback/ 401 Session 2024-09-27T10:35:00+08:00 10:35 00:05 - jcconf-2024-55223-cathay-financial-holdings-co-ltd Promotion zh-hant false https://pretalx.com/jcconf-2024/talk/PEPJVJ/ https://pretalx.com/jcconf-2024/talk/PEPJVJ/feedback/ 401 Session 2024-09-27T10:40:00+08:00 10:40 00:45 2024 年的 Java 22 和 23 延續了之前版本的功能，正式提供了匿名變數與模式、外部函式與記憶體存取 API，並且也新增了有趣的 Markdown 文件註解和直接執行跨檔案的源碼程式等功能。同時，持續孵化中的項目有彈性的建構函式、字串模板、向量處理、串流收集器、隱式宣告類別和實例主方法、基本型別的模式匹配，以及模組 import 宣告等功能。本場演講將與大家分享這兩個版本所帶來的 Java 最新變化。 jcconf-2024-52150-java-22-23 401 Joseph Kuo zh-hant false https://pretalx.com/jcconf-2024/talk/JSDXZ7/ https://pretalx.com/jcconf-2024/talk/JSDXZ7/feedback/ 401 Session 2024-09-27T11:25:00+08:00 11:25 00:10 - jcconf-2024-54489-break zh-hant false https://pretalx.com/jcconf-2024/talk/APR3L3/ https://pretalx.com/jcconf-2024/talk/APR3L3/feedback/ 401 Session 2024-09-27T11:35:00+08:00 11:35 00:05 Autopass 創立於台灣，以「車主的錢包」為初衷專注於出行金融支付整合。目前與全台超過 2,000 個出行場景合作，並以「⾞⿇吉」App累積超過百萬會員數。2023年將業務拓展至海外，目標讓全球車主都能享受到快速且便利的出行體驗。 jcconf-2024-54881-autopass Promotion zh-hant false https://pretalx.com/jcconf-2024/talk/RVVPPK/ https://pretalx.com/jcconf-2024/talk/RVVPPK/feedback/ 401 Session 2024-09-27T11:40:00+08:00 11:40 00:45 In this talk, Kim'd love to share how an problem solver start their problem framing process, through identifying key functional requirements, quality attributes, operation considerations and final design trade offs.

Pure functions and immutable data are all well and nice, but what should we do when we need to read from a database, send data over the network, or access local files? In this talk, "Functional Programming IO Demystified: Understanding Partial Application, Monads, and Effects," we will explore these concepts using practical examples and live coding in Kotlin. Each strategy has its pros and cons, and I will illustrate them with examples from my experience working on large back-end code bases in functional Kotlin. Key takeaways from this talk include: A better grasp of how to design a functional programming solution for a backend. Understanding advanced functional programming concepts, including the differences between the monadic approach and the direct-style effects approach.

Scala is not far behind, and its upcoming direct style implementation promises to revolutionize how we tackle concurrency challenges. In this talk, we'll dive into direct style programming in Scala 3, unlocking the potential of structured concurrency and harnessing the benefits of Project Loom in Java 21+. Discover how Scala's direct style goes beyond the capabilities of other languages, providing a seamless integration with functional programming paradigms and offering a compelling alternative to the love-hate relationship with monadic effects. Join us to learn how to: * **Simplify concurrent code:** Write code that reads like synchronous logic, while effortlessly managing asynchronous operations. * **Leverage structured concurrency:** Ensure well-defined task lifecycles and error handling for robust concurrent applications. * **Embrace a functional approach:** Experience how direct style complements and enhances functional programming techniques in Scala. * **Unlock new possibilities:** Explore how Scala's direct style opens doors for innovative solutions in concurrent and asynchronous programming. Whether you're a seasoned Scala developer or new to the language, this talk will equip you with the knowledge and tools to master direct style and conquer the complexities of concurrent programming with elegance and power. jcconf-2024-51233-direct-style-in-scala-conquering-concurrency-with-elegance-and-power 203 張瑋修 Walter Chang zh-hant false https://pretalx.com/jcconf-2024/talk/7DHSPF/ https://pretalx.com/jcconf-2024/talk/7DHSPF/feedback/ 203 Session 2024-09-27T17:15:00+08:00 17:15 00:45 The world has changed — everything is fast. You’re busy updating your technical skills, but are you leveraging the most efficient learning techniques? Are you building your network in a systematic way. Are you contributing to communities? There are massive benefits to contributing to Open Source projects, especially Java as one of the more innovative and long lasting software development communities in the world. But remember that although communities are fun and valuable they can also be fragile and change radically. They need continual nurturing so they can support opportunities for contributors. In this session, we’ll explore the skills necessary to learn new things deeply, contribute things of value to communities, and build our own innovative networks to leverage markets. The result is that we benefit, the community benefits, our friends benefit, and our employers benefit. These four levels represent reciprocal relationships that need careful consideration. We'll talk about concepts from network science, neuroscience, education, and history, while also introducing practical simple tools like spaced repetition algorithms to help promote memory and learning. I’ll share some career success stories of my own and also some of my catastrophic failures. I’ve photographed thousands of developers and interviewed hundreds of them for videos, streams, and podcast, so we surely have many images to show and many lessons we can discuss to help us all thrive in this crazy fast world. jcconf-2024-50399-developers-build-your-career-now 203 Jim Grisanzio zh-hant false https://pretalx.com/jcconf-2024/talk/FWWQHW/ https://pretalx.com/jcconf-2024/talk/FWWQHW/feedback/ 403 Workshop 2024-09-27T14:00:00+08:00 14:00 03:00 使用 Spring Boot + Spring AI 結合各種 AI 模型工具，快度打造 AI 應用 - Spring AI 介紹 - 建立 project（以下都是講解+實作） - 基本 Chat 呼叫 - 產生圖檔天氣貓貓圖 - Embedding - 向量資料庫 - 打造自己的知識機器人 jcconf-2024-51035-spring-ai--ai 403 Jiayun Zhou zh-hant false https://pretalx.com/jcconf-2024/talk/TFVXVT/ https://pretalx.com/jcconf-2024/talk/TFVXVT/feedback/
