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.

Crossing Over – Working across Java and Kotlin

This chapter will explore the practical ramifications of adding Kotlin to an existing Java code base. Because rewriting an application from scratch in a new language is a risky and rare endeavor, this chapter details how to work with both Java and Kotlin in a single code base. It explores some of the challenges associated with adding Kotlin to an existing Java code base, such as the differences in the null handling and the lack of Kotlin features in Java. Finally, it will examine common Kotlin idioms and how they affect the way you write code with both Kotlin and Java.

The following topics will be covered in this chapter:

  • Working with Kotlin from Java
  • Working with Java from Kotlin
  • Impacts and considerations when working with both Java and Kotlin in the same code base
  • Embracing Kotlin idioms
