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 1

  1. Kotlin's popularity has skyrocketed in recent months due to the fact that it is a simple and concise language that is easy to learn and supports object-oriented and functional programming. Kotlin is a superset of Java that avoids all unwanted Java features, such as verbose, unsafe, and outdated syntax, and includes powerful features from different languages. These features include security, simplicity, and interoperability.
  2. Type inference is a mechanism where the Kotlin compiler plays its role in establishing the type of variable. Kotlin will determine the data type by understanding the value assigned. It intelligently infers the type by the value, and then makes the data type variable respectively.
  3. Null ability is one of the reasons that most applications crash. Kotlin is very strict when it comes to safety. When it comes to applications, users, especially mobile...
