In object-oriented programming, classes and objects are the key concepts to understand how we model elements of reality and define their structure and behaviour within software. Let’s look in detail at the anatomy of a class, how to create objects from it to use their properties and methods, and other key details of their relationship.
One of the fundamental pillars of object-oriented programming is encapsulation. This powerful characteristic allows us to control access to class members, hiding implementation details and protecting the state of our objects. In this article we will delve into the concept of encapsulation, the usefulness of getters, setters, public/private properties and methods, and the important benefits this provides us as developers.
