This project is an introduction to the Kotlin programming language. It covers many language features from nullable properties to extension functions and Java interoperability.

1. Getting Started
2. Project Structure
3. Lessons

This course requires the following to get started:

• Git
• Java 1.8
• IntelliJ Community Edition 2020.2 or later

Clone the repo into your desired location like so:

git clone https://github.com/AOrobator/IntroToKotlin.git

Next, open the IntroToKotlin project with IntelliJ.

You should now be able to run L0_HelloWorld.kt via a green play button in the gutter.

• This is a Kotlin only project that is broken into several packages. Each package goes over a specific concept in Kotlin. Even though this is a Kotlin only project, some Android concepts are covered.
• Most lessons have a main lesson file that goes over the concept being taught. Then there are labs that test understanding of each concept. Solutions are located on the master branch, but make sure to fully attempt each question before looking at the solutions.
