Learn Kotlin Programming - Second Edition

By: Stephen Samuel, Stefan Bocutiu

Overview of this book

Kotlin is a general-purpose programming language used for developing cross-platform applications. Complete with a comprehensive introduction and projects covering the full set of Kotlin programming features, this book will take you through the fundamentals of Kotlin and get you up to speed in no time. Learn Kotlin Programming covers the installation, tools, and how to write basic programs in Kotlin. You'll learn how to implement object-oriented programming in Kotlin and easily reuse your program or parts of it. The book explains DSL construction, serialization, null safety aspects, and type parameterization to help you build robust apps. You'll learn how to destructure expressions and write your own. You'll then get to grips with building scalable apps by exploring advanced topics such as testing, concurrency, microservices, coroutines, and Kotlin DSL builders. Furthermore, you'll be introduced to the kotlinx.serialization framework, which is used to persist objects in JSON, Protobuf, and other formats. By the end of this book, you'll be well versed with all the new features in Kotlin and will be able to build robust applications skillfully.

Summary

In this chapter, you learned how a microservice architecture recommends building a system as a collection of small and isolated services, where each service owns its own data and can be independently scaled to provide resilience to failure. These services interact with each other to form a cohesive system. We also learned Lagom, which is the new framework for developing reactive microservices on the JVM. There is far more to talk about when it comes to Lagom. It is a book on its own. Hopefully, this quick introduction has given you the appetite to go and learn more about it. You have seen how to enable Kotlin for the Lagom project, and now you can go on and utilize all the benefits of Kotlin to more quickly develop your next distributed system.

Chapter 13, Concurrency, of this book will be an introduction to concurrency. It will go over the terminology and how common concurrency...
