Hot and spicy Java with Lombok. Live!
summary
Live coding shows Lombok (Maven dependency + optional IDE plugin) replacing repetitive getters/setters, equals/hashCode, toString and constructors so a simple Whisky class shrinks ~4x and tests stay green after swaps. Examples build Barrel, Bottle and Bar classes using @Data, @Builder, @Value, plus @Synchronized and @SneakyThrows; Delombok/Delombok plugin reveals generated sync blocks and exception-wrapping tricks. Caveats: hidden API changes, fluent/builder renames can break callers, and local var usage can obscure return types.
