Hands-On Object-Oriented Programming with Kotlin

Class properties

In Kotlin, each class property is considered a first-class citizen, which we discussed in the Properties – A first class citizen section of Chapter 2, Introduction to Object-Oriented Programming. In this section, we will learn more about properties and how to define the getter and setter functions that are explicitly provided by Kotlin. Let's create a Person class with two properties, name and age:

class Person {    var name: String = ""     var age : Int = 0 }
