title: Is it necessary to have getters and setters in POJO's
body: <p>I have been going through clean code book which states that the class should not expose the internal state of its data and only should be exposing the behavior. In case of a very simpl and dumb java bean exposing the internal state which getter's and setters, is it not worth just removing them and make the private members public? Or just treat the class as a data structure?</p>
