This is a course on the Kotlin programming language. Kotlin is a programming language made by JetBrains which targets the JVM. Kotlin is designed to be a better Java. It is more concise, safer, has better support for functional programming and is designed to speed up everyday development tasks. Kotlin also has great tool support, since it's made by the makers of IntelliJ IDEA, the world leading IDE.

This course is designed for people already familiar with Java who are looking for a more modern, expressive and powerful language for the JVM.

In this course, you will learn about:

• How to install and run Kotlin and why toolability matters (I use IntelliJ)

• Type inference and how it can save you a lot of time

• Smart control flow structures that let you write more succinctly

• Mutability options (val and var), what they mean and how to use them

• Nullability guarantees and how they make your code more safe

• The power of functional literals (nested functions and lambdas)

• Powerful built-in delegation functionality

• How to leverage Kotlin's collection operations to process data sets efficiently

...and a lot more!

This course is completely live-demo based. All the lectures are examples of real code being edited and executed using the IntelliJ IDEA Community Edition IDE.

Update: Google has just announced official support for Kotlin on Android. Congratulations to the Kotlin team!
