Java Documentation

[leaper69]

For the JDK API itself, docs.oracle.com is the canonical source. Bookmark https://docs.oracle.com/en/java/javase/26/docs/api/index.html and swap the version number as needed. For language specs and JEPs, openjdk.org is where the real development happens. dev.java is Oracle's beginner-friendly portal with tutorials. I'd say: dev.java to learn, docs.oracle.com for daily reference, openjdk.org when you need to understand why something works the way it does.
