Hands-On Design Patterns with Kotlin

By: Alexey Soshin

Overview of this book

Design patterns enable you as a developer to speed up the development process by providing you with proven development paradigms. Reusing design patterns helps prevent complex issues that can cause major problems, improves your code base, promotes code reuse, and makes an architecture more robust. The mission of this book is to ease the adoption of design patterns in Kotlin and provide good practices for programmers. The book begins by showing you the practical aspects of smarter coding in Kotlin, explaining the basic Kotlin syntax and the impact of design patterns. From there, the book provides an in-depth explanation of the classical design patterns of creational, structural, and behavioral families, before heading into functional programming. It then takes you through reactive and concurrent patterns, teaching you about using streams, threads, and coroutines to write better code along the way By the end of the book, you will be able to efficiently address common problems faced while developing applications and be comfortable working on scalable and maintainable projects of any size.

Summary

So, in this chapter, we covered the main goals of the Kotlin programming language.

We went through the variables that are defined, such as val, var, null safety, and type inference. We observed how program flow is controlled by commands such as if, when, for, and while, and we also took a look at the different keywords used to define classes and interfaces: class, interface, data, and abstract class. We learned how to construct new classes and how we inherit from interfaces and implement classes. And finally, we learned what design patterns are good for, and why we need them in Kotlin.

In the next chapter, we'll start discussing the first of the three design pattern families: creation patterns.
