It’s time for Java 18! Along with thousands of performance, stability, and security updates, Java 18 delivers nine enhancements and changes (known as JDK Enhancement Proposals, or JEPs), including two delivered in incubator modules and one preview language feature.
The nine JEPs delivered with Java 18 are grouped into four categories.
- Core library improvements and updates
- Tooling improvements
- Previews and incubators
- Deprecations
See all the JEPs in Java 18 through the videos created for Oracle Developer Live: Java Innovations.
In particular, I recommend the technical presentation by Aurelio Garcia-Ribeyro, senior director of product management for Java SE: “New in JDK 18: Reviewing enhancements in the latest JDK release.”
