Kotlin Workshop

Kotlin Logo

A Kotlin workshop intended to be taught in two days.


This workshop is divided into two parts

  • Introduction to Kotlin
  • Advanced Kotlin

It consists of

  • Instructor Project: Used to explain concepts, with existing code samples
  • Student Project: For students to complete
  • Presentations: For the instructor to use
  • Questions: For students to complete

Both the Instructor Project and the slides have Introduction and Advanced modules included. While the Introduction has a lot of pre-built examples, it also serves as a canvas to show more code while teaching. However, please make sure that if you're a contributing author to this project, that you do not check-in any ad-hoc code. It's also recommended to use Scratch files in IntelliJ IDEA for this purpose.


Slides for the workshop lead by Hadi Hariri can be found here.

Presentations used for the workshop at KotlinConf:

  1. Intro
  2. Nullable Types
  3. Object-Oriented Programming in Kotlin
  4. Kotlin Types
  5. Functional Programming in Kotlin
  6. The Power of inline
  7. Lambda With Receiver
  8. Conventions
  9. Intro to Coroutines


Questions can be found here. The keys to the questions are in the module instructor/quizzes.
