Java 19 Features in Action - Building a GitHub Crawler
Explore the new features of Java 19 in this 38-minute video tutorial that demonstrates their practical application through the creation of a GitHub crawler. Dive into virtual threads, structured concurrency APIs, sealed types, and pattern matching in `switch` - all preview features in this release. Begin with an introduction to the crawler and a warm-up using records. Learn about virtual threads and their implementation with a blocking HTTP client. Discover structured concurrency using StructuredTaskScope, concurrent data structures, and records with collections. Gain insights into debugging techniques for structured concurrency. Examine Data-Oriented Programming (DOP) concepts, including type hierarchies, type pattern switches, and deconstruction patterns. Address common misconceptions about the use of `instanceof`. Access the complete source code on GitHub and explore related topics through linked videos on string templates, virtual threads, and more.
