Mastering Kotlin

By: Nate Ebel

Overview of this book

Using Kotlin without taking advantage of its power and interoperability is like owning a sports car and never taking it out of the garage. While documentation and introductory resources can help you learn the basics of Kotlin, the fact that it’s a new language means that there are limited learning resources and code bases available in comparison to Java and other established languages. This Kotlin book will show you how to leverage software designs and concepts that have made Java the most dominant enterprise programming language. You’ll understand how Kotlin is a modern approach to object-oriented programming (OOP). This book will take you through the vast array of features that Kotlin provides over other languages. These features include seamless interoperability with Java, efficient syntax, built-in functional programming constructs, and support for creating your own DSL. Finally, you will gain an understanding of implementing practical design patterns and best practices to help you master the Kotlin language. By the end of the book, you'll have obtained an advanced understanding of Kotlin in order to be able to build production-grade applications.

Bringing static to Kotlin

Kotlin doesn't have a static keyword like Java does. Kotlin idioms rely on concepts such as top-level functions and properties, extension functions, and compile-time constants to achieve the same functionality without the need for an explicit static keyword. If you're working strictly within a Kotlin code base, this doesn't pose much of a problem, but if you're working across both Java and Kotlin, there may be times when you want to expose properties or methods as static so they can be used more naturally from Java. In this section, we'll learn how to expose Kotlin elements as true JVM static elements so they can be used more naturally from Java.

Where can we use JvmStatic?
