Yeah, my Java code pretty consists of two categories of class types now days. Pojo's which are just data structures or a glorified HashMaps for holding data. And, if allowed, using Lombok to get rid of all the getter/setter cruft. The second category of class types are just Service classes. These classes hold no state and are a logical grouping of methods that typically operate on a given data type. However, the class is based more on a specific role it performs than the type(s) it operates on. Also, there's considerable thought given to reuse of the Service classes outside the given context at hand.
