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.

Section 1: Fundamental Concepts in Kotlin

In the first section of the book, you will be introduced to Kotlin. You will learn how to set up your system to write your first Kotlin program and run it. This will include configuring a build system, such as Gradle or Maven, to handle dependencies used by your programs. Then, the core concepts of Kotlin, such as basic syntax for variables and values, expressions, and loops, will be explained, giving you the basic building blocks required to write a non-trivial program. In addition, the types available in Kotlin, and how nulls interact with them, will also be covered. Finally, you will see how the basic constructs of Kotlin can be combined to form objects, and how these objects can interact in what is known as object-oriented programming.

The following chapters will be covered in this section:
