Java champion and legend Dr. Venkat Subramaniam discusses amazing features in Java 21, including virtual threads and reactive programming. They talk about Java's evolution, the importance of meeting developers where they are, and conference planning. The host expresses love for the conversation and invites listener contribution and feedback.
Virtual threads in Java provide scalability and efficiency in multi-threaded applications, while pattern matching offers a concise and efficient approach for handling different implementations based on object type.
Deep dives
Java Virtual Threads
Virtual threads in Java enable asynchronous and non-blocking communication, providing scalability and efficiency in multi-threaded applications. They allow developers to leverage existing code with executor services and seamlessly switch to virtual threads for non-blocking behavior. Virtual threads are particularly beneficial for IO operations, reducing context switching and improving scalability without the need for elastic scaling.
Pattern Matching vs Polymorphism
Pattern matching in Java offers an alternative to polymorphism when handling different implementations based on object type. While polymorphism is powerful, pattern matching provides a more concise and efficient approach for switching between different implementations, especially in scenarios like message handling. It allows developers to avoid excessive if-else or instance of checks and enables better code organization and easier understanding of the codebase.
Language Evolution and Cohesion
Java's evolution has been characterized by cohesive and seamless enhancements that prioritize developer productivity. Unlike other languages, Java's evolution aims to integrate new features seamlessly with existing code, maintaining backwards compatibility and ensuring all versions of Java work cohesively. This approach enables developers to continue leveraging existing knowledge and code while benefiting from the latest language improvements.
The Future of Java and Kotlin
Java and Kotlin have symbiotic relationships in terms of language features and advancements. Java's improvements often benefit Kotlin, and Kotlin's innovations further push the boundaries for what's possible. Both languages cater to different needs and problem spaces, and their evolution focuses on making developers more productive by providing powerful and intuitive language features.
Hi, Spring fans! In this installment the good and the great Dr. Venkat Subramaniam rejoins the show, live from the fantastic VOXXED DAYS CERN event, to talk about some of the amazing features in Java 21
