What problem does it solve?
Java 21 introduces features that can dramatically improve concurrency, type-safety, and data immutability, but teams often struggle to adopt them consistently across codebases.
Core Features & Use Cases
- Virtual Threads for scalable concurrency with minimal boilerplate.
- Pattern Matching and Records to reduce boilerplate and improve readability.
- Sealed Classes for closed hierarchies and exhaustive handling.
- Use Cases: modernizing legacy Java apps, building new services, and teaching teams Java 21 patterns.
Quick Start
Experiment by refactoring a representative module to use Virtual Threads, Pattern Matching, Records, and Sealed Classes to observe performance and readability improvements.
