Object-Oriented Programming in Kotlin (Kotlin Tutorial #4)

Object-Oriented Programming (OOP) is a paradigm that uses “objects” to design applications and computer programs.

It utilizes several techniques from previously established paradigms, including modularity, polymorphism, and encapsulation.

Kotlin, a statically typed programming language developed by JetBrains, has become increasingly popular for its concise syntax, interoperability with Java, and its support for functional programming features.

However, its capabilities in object-oriented programming are particularly noteworthy and offer a modern touch to this traditional paradigm.

Understanding the Basics of OOP in Kotlin

Classes and Objects

In Kotlin, everything is an object, which means every entity is an instance of a class. A class in Kotlin is defined using the `class` keyword. It can contain data members (properties) and member functions (methods). Kotlin also allows for concise syntax, where a class with no body can omit the curly braces.

class Car(val make: String, val model: String)

Here, `Car` is a simple class with properties `make` and `model`. Kotlin automatically provides a default constructor with these properties.
