Java 18 is still six months away but is already taking shape, with four feature proposals anticipated for it so far, the latest being a third incubation of the vector API.
The OpenJDK page for Java Development Kit (JDK) 18 lists the vector API, code snippets, and the UTF-8 charset as proposed to target JDK 18, as of September 20. The JEP (JDK Enhancement Proposal) index of Java technologies also cites the record patterns and array patterns proposal as eyed for JDK 18, although it has not been officially targeted yet.
