Kotlin Essentials

Overview

Discover why Google has pinned Kotlin as the preferred language for Android development with this 2-day course. You will learn Kotlin development techniques and language principles, and will walk away knowing how to migrate existing Java projects to Kotlin.

Who Should Take This Course

• Developers who are looking to explore the Kotlin language.

• Developers who wish to see both object-oriented and functional programming paradigms implemented in a modern JVM language.

• Developers interested in learning a language with multi-platform applications.

• Android developers who want to learn new skills to advance their career.

• Teams looking to upgrade their applications from Java to Kotlin.

 

Syllabus

The Basics

• Understand writable and read-only properties and take a look at Kotlin’s type system.

• Work with control flow statements as assignable expressions.

• Learn about defining class- and file-level functions and specifying their return types.

• Leverage Kotlin’s built-in numeric and string types.

• Differentiate nullable and non-nullable types and how to work with null safely.

• Understand safe exception handling in Kotlin.

Collections and Functional Programming

• Learn how to represent series of data with mutable and read-only collection types.

• Take a closer look at collections, including destructuring, type checking, smart casting, and type parameter constraints.

• See how to pass functions as arguments, lambda notation, and function references.

• Use functional programming paradigms to write complex algorithms using just a few operations, including map, flatMap, associate, filter, zip, and fold.

• See Kotlin’s scope functions — apply, let, run, with, also, takeIf, and takeUnless — and use them to write more concise and idiomatic Kotlin code.

Objects Oriented Programming

• Apply object-oriented programming concepts in Kotlin to define your own types.

• Learn about constructors, preconditions, and initialization requirements for object creation.

• Inherit and override class behavior using abstract and open classes.

• Define general sets of behaviors using interfaces.

• Learn how to use data classes and object declarations to create data wrappers and singletons with implementations that are automatically generated at compile time.

• Learn how to define algebraic data types with enums and sealed classes.

• See how to define value classes to create more efficient classes that wrap a single property.

Advanced Kotlin

• Understand type variance and generic type parameters.

• Use extensions to add functionality to a type without modifying the original class.

• Leverage coroutines to efficiently and safely move work between threads.
