Lombok's Data classes are very much like Scala's case classes, although Scala's version is richer.
In addition to the constructor, toString, equals, hashcode and accessors, they add support for Scala's Product trait, the copy method, and the canEqual method. Being Scala, you also get to use them when pattern matching.
