Java 20, the next planned version of standard Java, has its first feature proposal: Pattern matching for switch statements and expressions will be previewed for the fourth time in the forthcoming Java SE (Standard Edition) release.
While OpenJDK’s JDK (Java Development Kit) 20 web page still lists no features for the planned release, the Java Enhancement Proposal (JEP) index cites a fourth preview of pattern matching for switch as targeted for JDK 20. JDK 20 is due next March.
