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.



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.

What our students have to say

I did the swift and iOS bootcamp in Georgia. It was incredible and totally worth it. I had only played around and pieced together iOS apps before I went to the bootcamp. After everything made so much more sense and I was able to create and publish new iOS apps with ease.

Anna Sherman, Developer, Carbon Five

I used other online free courses to learn basic Kotlin and some advanced topics. It was nice to have the classroom setting, with the Kotlin Essentials course, to gain better-detailed knowledge. I do feel more confident with the basics of Kotlin, and I am looking forward to taking the more advanced courses.

I was able to start my research lab, HealthHawks, because Big Nerd Ranch gave me the skills to build software on mobile applications. I equip medical professionals with software that they test to be able to determine if it helps clinical outcomes. It is awesome. Big Nerd Ranch taught me how to change the world for the better, one line of code at a time.
