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 2

  1. A class is a well-defined idea that explains the existence of an entity. A class is a template that contains lists of two things—attributes and behaviors. The object is an instance of a class, an entity that contains all attributes and behaviors that a class describes.
  2. Every class contains a number of attributes and behaviors. Attributes are the characteristics of the class that help to distinguish it from others. Behaviors are the tasks an object should perform.
  3. A constructor is a special type of function used to initialize the properties of the class. Kotlin provides three constructors—a default constructor, a primary constructor, and a secondary constructor.
  4. Function overloading is a feature where a class can have more than one function with similar names. Each function is uniquely identified by its parameters.
  5. Data classes are special types of classes...
