This is the same examples as in the recording, with the exception of using packages instead of inner classes.
Dependency from model to view
An example of a dependency from the model to the view. This is NOT what we want and it is a violation of the model-view separation principle
A view class ConsolePersonPrinter is used as an argument to Person.print this creates a dependency from Person to ConsolePersonPrinter.
view Responsibility in model
In this example the model class Person has some responsibility (functionality) that should rather be a part of some view class (Person.getName()). This is tricker to spot as it does not form a direct dependency. Common signs are custom formatting of strings (as in the example), use of user interface api:s (e.g. 'system.out.println'), or even helper methods that cater for a specific view funtionality only.
This is NOT what we want and it is a violation of the model-view separation principle

Reading
The influential software architecture paper describing different architectural views for a system. Note that in this paper an old noation (Booch-notation) is used, i.e. it was written before the method-wars was over and before UML was an accepted standard notation. You need of course not know this notation. Architectural Blueprints—The “4+1” View Model of Software Architecture
A book about architectural software patterns, like Layers, Model-View-Controller etc.
