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 8

  1. Interoperability refers to the ability to use both Java and Kotlin languages in a single project. We can call Kotlin functions in Java, as well as Java methods and variables in Kotlin code. This gives us the advantage of code reusability. For example, if we have an existing Java project with classes and functions, then we do not need to rewrite everything in Kotlin from scratch. Instead, we can use each and every line of Java code in Kotlin.
  2. JVM annotations are used to make the Kotlin code simple and clean for Java developers. @file: JvmName helps us to use another Kotlin filename. jvmName(functionName) is used to assign a new name to the existing function, and @JvmStatic helps to call static functions from Kotlin.
