Object-Oriented Design Patterns Explained with Stories from Harry Potter

Here is a book that takes the sting out of learning
object-oriented design patterns! Using vignettes from the fictional
world of Harry Potter, author Avinash C. Kak provides a refreshing
alternative to the typically abstract and dry object-oriented
design literature.



Designing with Objects is unique. It explains design
patterns using the short-story medium instead of sterile examples.
It is the third volume in a trilogy by Avinash C. Kak, following
Programming with Objects (Wiley, 2003) and Scripting with Objects
(Wiley, 2008). Designing with Objects confronts how
difficult it is for students to learn complex patterns based on
conventional scenarios that they may not be able to relate to. In
contrast, it shows that stories from the fictional world of Harry
Potter provide highly relatable and engaging models. After
explaining core notions in a pattern and its typical use in
real-world applications, each chapter shows how a pattern can be
mapped to a Harry Potter story. The next step is an explanation of
the pattern through its Java implementation. The following patterns
appear in three sections: Abstract Factory, Builder, Factory
Method, Prototype, and Singleton; Adapter, Bridge, Composite,
Decorator, Facade, Flyweight, and Proxy; and the Chain of
Responsibility, Command, Interpreter, Iterator, Mediator, Memento,
Observer, State, Strategy, Template Method, and Visitor. For
readers? use, Java code for each pattern is included in the
book?s companion website.

• All code examples in the book are available for download on a
  companion website with resources for readers and instructors.


• A refreshing alternative to the abstract and dry explanations
  of the object-oriented design patterns in much of the existing
  literature on the subject.


• In 24 chapters, Designing with Objects explains well-known
  design patterns by relating them to stories from the fictional
  Harry Potter series
