Object-Oriented Programming Basics
When we start using Java, object-oriented programming (OOP) is one of the most important topics to understand, and lacking a solid foundation can lead to challenges. Even for something as basic as a "Hello World" program in Java, we need to understand the concept of classes and methods. Additionally, concepts such as access modifiers and constructors are just the beginning of the many topics that need to be understood as we dive deeper into Java.
That is why we want to explore some of these concepts in this chapter, taking into account their roles in Kotlin. However, we are also very interested in addressing topics that play a crucial role in getting the benefits of a programming language such as Kotlin, in which the goal is to not only eliminate the verbosity of the code but also to ensure clear and efficient programming.
Conversely, Kotlin introduces elements such as Unit, which differ from Java, and it’s important to examine...
