Introduction
Java 21 introduced a number of new features that are designed to help developers craft enterprise-level applications. These enhancements can improve how quickly and smoothly applications run while making coding simpler for developers. Highlights include:
- Lightweight Threads (Project Loom): They help developers manage multiple operations concurrently, as they simplify the handling of numerous tasks simultaneously. This is particularly beneficial for complex services.
- Pattern Matching for Switch: It makes writing conditions in your code neater and easier to understand.
- Overall Improvements: They enhance security, stability and make development smoother.
