If you not only want to know what “Object-Oriented Programming” means, but are also interested in its origins and what it can achieve, start here, at the very beginning. Let Francesco take you on a journey. Learn about the essence of good objects and write good stories that those objects can tell.
This Training is organized in six courses.
"Isn't it the Model-View-Control (MVC) Pattern?" "No!"
There is much, much more to it than that.
The basic dynamic of this pattern is extremely interesting. The message inversion mechanism that characterises this design pattern is so relevant that if taken to an extreme, it can lead to leaving the Object-Oriented Paradigm and entering the Event-Driven Paradigm.
In this course, Francesco Cirillo explores the basic dynamics of message inversion typical of this pattern. He begins by showing how to implement simple functional behaviours with this dynamic.
Francesco then addresses a number of significant variations of the pattern. Not only architectural variations are shown: for example MVC and Subscription-Publishing. He also shows the variations that make the pattern's dynamics useful for implementing and simplifying the development of complex functional behaviours.
We need two projects to fully understand how to implement this design pattern.
The first project we apply a pattern to is the Calculator. This is the classic domain for applying Strategy or Commands. Is it possible to effectively implement the logic of a Calculator with the Observer pattern? The definition of effective we use is reducing the cost curve of change.
The second project is related to the Visicalc Challenge. One of the most useful functions of a spreadsheet is recalculation. Change the value of a cell and the whole sheet magically updates. Is it possible to apply the Observer pattern to solve this functionality? Or is this one of those cases where this pattern makes the system more complex? If so, what other patterns might be more effective in reducing the cost of change?
"Isn't it an Adapter?" "NO!"
The Bridge pattern has the reputation of being a "difficult," unclear pattern. It is a somewhat obsolete "architectural" pattern to be used at a low level for the development of user interface components. The Bridge pattern is one of those 'mysterious' patterns, along with the Flyweight of the Gang of Four's 23 that developers never used. This pattern can actually be very effective for demultiplying the complexity of numerous user stories and not only for non-functional matters.
The first objective of this course is to clarify the dynamic difference between this pattern and other patterns such as the Adapter Pattern or the EnvelopeLetter or ShieldPattern idiom that are often confused with the Bridge. We then deal with variations of the Bridge pattern. Yes, there are quite a few. And often the variations coincide with different applications.
The Bridge Pattern requires development to be understood.
We apply the Bridge Pattern to develop a... Video Game!
And let me be clear: we do not apply it to solve the low-level user interface or some kind of platform issue. We use the Bridge Pattern to solve and implement a functional issue related to a certain Video Game.
"Isn't it to clone objects?" "Well, it’s not only for that!"
Actually, the Prototype pattern is extremely fascinating: it might represent the future of objects and programming. In fact, languages such as Self and Javascript were born on the basis of this pattern.
The Prototype pattern is another little known and used pattern. Those who know a little more about design patterns apply it to clone objects.
The first thing we study is the dynamics of this pattern. This allows us to consider interesting variations of this pattern.
"How about Self?""
When I had to think about an application of this pattern, I had no doubts.
How can we implement some behaviour to develop a mini-Self language by applying the Prototype pattern?
And maybe build a simple video game?

Francesco Cirillo has worked at the forefront of the software industry for more than 30 years. In a career spanning startups, corporations and freelance consulting, he has mentored thousands of professionals, developers, managers and software teams.
In the 1990s he worked as a Senior Consultant and Mentor for Sun Microsystem, expert in Software Architectures and Software Development Processes and Java and Object-Oriented Evangelist.
Francesco is one of the pioneers of Agile Methods. He started working on XP and TDD in 1999. He was chosen by Kent Beck to develop the XP community in Europe and as reviewer of the second edition of the book Extreme Programming Explained. In 2000 he created XPLabs, the first company in Europe to offer comprehensive services on XP: software development, training and consulting.
In 2007 he created the Anti-IF Campaign to raise awareness in the international community of software developers to apply good design principles to grow software in a sustainable way.
Since 2008 Francesco stopped actively working on Agile Methods and started to develop RRP, a new method of software development. In 2013 he created Cirillo Consulting based in Berlin to offer professional training and consulting on productivity and software development.
Francesco invented the Pomodoro® Technique, a renowned time-management method used by millions of people all over the world, while being a university student looking for a way to get more done in less time.
