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.

Chapter 3: Understanding Programming Paradigms in Kotlin

  1. What is a programming paradigm?
  • A programming paradigm is a way of classifying a programming language based on common features or patterns of that language.
  1. Can you name three programming paradigms supported by Kotlin?
  • Imperative
  • Functional
  • Object-oriented
  • Reactive
  • Generic
  1. What is the difference between imperative and declarative code?
  • Imperative describes "how" to do something. Declarative describes "what" to do.
  1. Can you name one declarative programming language?
  • SQL
  1. What are the three core principles of object-oriented programming?
  • Encapsulation
  • Polymorphism
  • Inheritance
  1. What are two core principles of functional programming languages?
  • First-class functions
  • Pure functions
  1. What is reactive programming?
  • A style of programming in which computation is done in response to streams...
