The Arrival of Java 25
Briefly

The Arrival of Java 25
"New in this release JDK 25 delivers sixteen enhancements that are significant enough to warrant their own JDK Enhancement Proposal (JEP), including four preview features, one experimental feature, and one incubator feature. These features cover innovations to the Java language to the libraries (with two improvements specifically to security libraries), performance and runtime, and monitoring improvements. Language Innovation Primitive Types in Patterns, instanceof, and switch 3rd Preview"
"Module Import Declarations [JEP 511] Enhances the Java programming language with the ability to succinctly import all of the packages exported by a module. This simplifies the reuse of modular libraries but does not require the importing code to be in a module itself. Compact Source Files and Instance Main Methods [JEP 512] Evolves the Java programming language so that beginners can write their first programs without needing to understand language features designed for large programs."
JDK 25 is generally available and delivers sixteen enhancements across the language, libraries, performance, runtime, and monitoring. The release includes four preview features, one experimental feature, and one incubator feature. Language innovations include primitive types in patterns, instanceof, and switch (3rd preview, JEP 507); module import declarations for succinctly importing packages exported by a module (JEP 511); compact source files and instance main methods for simplified single-class programs (JEP 512); and flexible constructor bodies that allow statements before explicit constructor invocations (JEP 513). Two improvements target security libraries while other changes improve performance and monitoring.
