What is procedural code? Program flow is focused on methods Methods are also..  Functions  Sub (VB notation)  Procedures Public methods must get all their needed parameters:  Mostly by arguments  Sometimes as configuration Demo...

What is procedural code? Implementation details are exposed to programmers Example: Fetching data from an external resource:  Transport: HTTP? FTP? POP3?  Username, password?

What is OOP code? Program flow is focused on interfaces and events Implementation details are hidden from the programmer Changing the implementation is (or should be) easy The hard part: Modeling Demo...

Procedural Code Indicators Static methods Singletons Code heavily relies on configuration

OOP – The Good Maintainability Testability Programmers focus on interfaces and not on implementation  Program flow is clear Loose coupling

OOP – The Bad Over engineering  Lots of files  We might end up with nano services Modeling might be hard, or difficult to change  We sometimes need for an architect or seniors

Is this OOP? In general – yes C# is a static language.. .. and so is Java.. We get class oriented programming:  Lots of classes to handle
