Kotlin Primer

Overview

Kotlin is a fantastic new language that we'll be using to create our Android Applications. In this module, we'll quickly explore the basics of the language from a Java perspective.

During the rest of the course, I'll often explain some of these concepts in more detail.

In this module, the Kotlin samples are live! I'm using Kotlin Playground to execute each sample when you press the green arrow to the right. You can even edit the samples if you want to try something a little different (reload the page to go back to the original sample).

Note

Not all code snippets are runnable, and those won't have the green arrow. If you don't see the green arrow buttons on any samples, press F5 to reload the page. There are sometimes caching issues when I make changes to the pages.

fun main() {
    println("Hello!")
}
