Hands-On Object-Oriented Programming with Kotlin

By: Abid Khan, Igor Kucherenko

Overview of this book

Kotlin is an object-oriented programming language. The book is based on the latest version of Kotlin. The book provides you with a thorough understanding of programming concepts, object-oriented programming techniques, and design patterns. It includes numerous examples, explanation of concepts and keynotes. Where possible, examples and programming exercises are included. The main purpose of the book is to provide a comprehensive coverage of Kotlin features such as classes, data classes, and inheritance. It also provides a good understanding of design pattern and how Kotlin syntax works with object-oriented techniques. You will also gain familiarity with syntax in this book by writing labeled for loop and when as an expression. An introduction to the advanced concepts such as sealed classes and package level functions and coroutines is provided and we will also learn how these concepts can make the software development easy. Supported libraries for serialization, regular expression and testing are also covered in this book. By the end of the book, you would have learnt building robust and maintainable software with object oriented design patterns in Kotlin.

Chapter 3

  1. Inheritance is one of the key concepts in object-oriented programming that helps in avoiding code repetition, especially where different classes have common features and all the classes belong to the same type
  2. Encapsulation is an object-oriented programming technique that involves binding data and functions into one unit, which is called a class. All properties and functions of the class are tightly coupled and combined in a single place.
  3. A visibility modifier helps to set the visibility of functions and properties to achieve encapsulation. A rule of thumb of encapsulation is to restrict those properties accessible to the outside the world and instead implement some functions to access them indirectly. Public, private, protected, and internal are four visibility modifiers provided by Kotlin.
  4. Kotlin provides four different types of inheritance:
    • Single inheritance
    • ...
