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.

Embracing Kotlin idioms

When introducing Kotlin to an existing code base, it's beneficial to be aware of common Kotlin idioms. Many of these common idioms can be used without a direct impact on interoperability; however, there are some common patterns in Kotlin that can impact interop, and you should be aware of them.

Goodbye helpers – embracing top-level and extension functions and properties

A common pattern in Java is to have the helper and util classes that exist solely for the purpose of storing static methods and data that needs to be accessible to the code base. These are classes such as StringUtils, DateUtils, and ViewHelpers. In Kotlin, we have another option.

Top-level functions and properties allow us...
