Behavioral patterns

These design patterns are best practices to identify a simple way to realize relationships between entities in a given situation.

Let's jump on to our selective behavioral patterns one by one in order to see them in detail.

The template method pattern

The template method pattern basically defines the steps of an algorithm inside a class as a contract while deferring some of the steps (methods) to be implemented by the derived classes; hence, it primarily defines the structure via an abstract base class.

We will explain its implementation using an example in continuation of our sample for a GUI app we created earlier for the abstract factory pattern. In fact, within the same example app, we cover abstract factory, builder, and template method...
