Java 23: Restoring the Balance with Primitive Patterns - Inside Java Newscast #66

The ongoing introduction of pattern matching to Java has put more weight on some language features than on others and unbalanced the language. In Java 23, primitive patterns will fix this regarding primitive types in `instanceof` and `switch`. This episode also goes over other upcoming patterns (deconstruction, static, instance, and constant) and shows how they will build out pattern matching in Java.
