Become a Kotlin Developer able to create professional programs. Dramatically increase your career options.
We assume you have never programmed before in this course and start from scratch and show you step by step how to download and install the tools, through to writing your first programs, and from there we move to more and more of parts of the Kotlin language that you need to understand.
If you are already a programmer, you will still find value in this course – It’s very common for programmers to want to learn a second or third programming language, and doing so makes you more valuable and opens up career opportunities.
As this is a crash course you can get skilled in Kotlin, fast.
Here is what a student said about another of the instructors courses.
“Above expectations because bunch of other people don’t do as good on this topic. Goran, Congratz, you’ve always done a clear and excellent job. You aren’t lazy. I always take few courses on same topic so i can compare content and quality of explaining, really, thank you.” – cris S.
What version of Kotlin will I learn?
All videos in the course have been recorded using the very latest version of Kotlin. It’s recommended that you follow along with that version, but if you have an older version most of the course should work just fine.
Keep in mind there are constant updates to Kotlin. So if you see a newer version when you are installing it, then use that version.
What will you learn in the course?
You’ll learn the essential Kotlin skills needed to become employable as a Kotlin developer.
- Creating a Kotlin basic program
- All about the setting up and running Kotlin programs
- Data Types, Variables, Conditional Processing, Loops, Classes, Operators, Expressions – all the good stuff.
- Check out the curriculum on this page for a list of what is covered in the course.
In the course you will work with a lot of Kotlin example code. You will start with Kotlin code that was badly written. You’ll see why it’s bad, and then as you progress through the course, you will improve it and make the code bug free.
This approach, along with smaller snippers of code will help you become a programmer as well as think as a programmer. And as a result you will learn how to get the most out of Kotlin.
What you’ll learn
- Learn the core Kotlin skills needed to apply for Kotlin developer positions in just 15 hours.
- Have a fundamental understanding of the Kotlin programming language.
- Understand how to create your own Kotlin programs.
- Have the skills and understanding of Kotlin to confidently apply for Kotlin programming jobs.
- Be able to demonstrate industry best practices in the Kotlin code you write.
- Obtain a solid understanding of what debugging and refactoring is and how to do it.
