Modern Java in Action by Nicolai Parlog

Modern Java applications can leverage records for clean domain modeling and data representation, with built-in immutability and generated methods like equals/hashCode

Sealed interfaces allow defining strict type hierarchies and controlling which implementations are permitted, helping with exhaustive pattern matching

Virtual threads enable high scalability for I/O operations without managing thread pools manually - they’re lightweight and managed by the JVM

The modern HTTP client (added in JDK 11) provides a clean API for making HTTP requests with features like immutable builders and body handlers

Pattern matching with instanceof and switch expressions allows cleaner handling of different types and destructuring of data

Records support constructor chaining and validation through compact constructors while maintaining immutability

The module system improves encapsulation and dependency management, though requires some initial learning curve

Structured concurrency APIs help manage parallel task execution with proper parent-child thread relationships

Preview features (like structured task scope) allow early access to upcoming Java features for experimentation

The jwebserver and jpackage tools enable quick local development and native application packaging without external dependencies
