This application helps to show some new features being introduced in Java versions until Java 25.
All relevant info is written down in comments inside sources.
This project requires Java JDK 25 to run. I namely use GraalVM for JDK 25 for development and testing.
Checkout the project and explore the files in your favorite IDE.
You can also mvn clean install the project and then just run java --enable-preview --add-modules=jdk.incubator.vector -jar target\JavaDemos-25.0.jar.
But you may miss some important context and information without reading the comments in the source code.
Using --enable-preview and --add-modules options is necessary to make the newest Java language features available.
Note: Until Maven 3.9.12 is released, you would see warning about Guice library using deprecated sun.misc.Unsafe class when running Maven install. This is known and about to be fixed.
You can help making this project better!
Look for the issues to see what can be done.
The most important rule: Your code must compile and run under Java 25. GitHub workflow is now set up to ensure this and PRs that cannot compile using mvn clean install will not be merged until the problems are fixed.
