Jdk 15: The New Features In Java 15 -
Both low-latency Garbage Collectors are now production-ready. Scalable, low-latency (sub-millisecond) GC.
A new platform-independent implementation of the EdDSA signature scheme. Higher security and performance. Found in the java.security package. 🛠️ JVM and Tooling Improvements ZGC and Shenandoah (Finalized) JDK 15: The new features in Java 15
Reduces pause times by performing evacuation work concurrently. Hidden Classes Both low-latency Garbage Collectors are now production-ready
Sealed classes and interfaces restrict which other classes may extend or implement them. Provides better control over inheritance. Useful for domain modeling and pattern matching. Syntax: public sealed class Shape permits Circle, Square {} Text Blocks (Finalized) Multiline string literals are now standard. Eliminates the need for most escape sequences. Automatically manages indentation. Uses triple quotes: """ ... """ . EdDSA (Edwards-Curve Digital Signature Algorithm) Higher security and performance
💡 JDK 15 made Java more readable with Text Blocks and more efficient with the finalization of the ZGC and Shenandoah garbage collectors.
