# Value objects

* AKA
  * domain objects
  * anaemic objects
* Just fields, immutable (no setters) never change
  * Equality based on values/properties of object (thus will need to override equals and hashcode) rather than identity
  * No Setters

    * Otherwise return copy in getter
* Can hold behaviour
