In this episode, David discusses with Gavin Bierman a new set of Java language features coming from Project Amber, i.e. Pattern Matching. In addition to sealed classes and pattern matching for instanceof, they are covering in great detail a new (and great!) JDK 17 preview feature: pattern matching for switch.
