10 KOTLIN TUTORIALS FOR BEGINNERS: DIVE INTO KOTLIN PROGRAMMING [VIDEO COURSE]


There is a serious lack of Kotlin tutorials for beginnersThe first Kotlin tutorial for beginners. You only find experienced Java developers hacking down Kotlin code in record time. Don’t get me wrong — those are really great for other experienced developers and I enjoy watching them. But for beginners, they are just voodoo code appearing on the screen like magic.

Kotlin is actually a great language to learn first, if only the necessary tutorials were out there. So I decided to create a course that even total beginners can follow. Check out the first 10 Kotlin tutorials below or check out the whole course (it’s $10 with the 95% reader discount).

#1: A Brief Overview of Kotlin

Learn where Kotlin comes from, the language concepts it incorporates, and why you should learn it.

 #2: Try It Out in 30 Seconds

This is a quick video for those who cannot wait to dive into code. Learn how to use the Kotlin online editor to try out some of the language basics.

#3: Installing the JDK

If you already have the Java Development Kit (JDK) installed, you can happily skip this step. If not, just follow this video and use this link that is mentioned in the video.

#4: Installing IntelliJ

If you don’t already have IntelliJ, you should change that right away — I really learned to love this powerful IDE. This tutorial guides you through the download and installation process. And here’s the link mentioned in the video.

#5: Setting Up IntelliJ

This tutorial covers just the most basic layout settings: how you can adjust the theme and font in IntelliJ to your favorite style.

#6: Using Kotlin Interactively in The REPL

The Kotlin REPL allows us to use Kotlin interpreter-style, so that we can put in an expression (or any line of code) and see what Kotlin does with it. It’s great to try out some basic expressions and calculations.

#7: Variables

It’s time to learn about variables in Kotlin. This tutorial covers how to create and use variables of different types and the differences of the val and var keywords (to create immutable and mutable variables, respectively).

#8: Basic Types & Strings

This tutorial covers all the basic types in Kotlin including strings. In the video, I go through the differences between the different data types for storing integer values, floating point numbers, text and logical values.

#9: Nullable Variables

Kotlin gets rid of the worst enemy of all Java developers — the NullPointerException. In Kotlin, you can use nullable types to decide which variables can be set to null and which cannot. By default, a variable just cannot be assigned to null.

#10: Your First Standalone Application

This tutorial covers how you can create a main() function in Kotlin to define the entry-point to your applications. Once you have made it through this lecture, you’re ready to go and really dive into development with Kotlin.
