Description

If you want to learn to program in Kotlin in far less time than you previously thought possible then read on.

The world today is a hectic place.  Most of us have very little spare time. Once we have worked (or studied), slept, spent some time with friends and family there is little time left to think about a career.

In order to become a software developer you need programming skills.  But how can you get those skills in the minimum amount of time and still have a life along the way?

This course was designed to teach you the essential Kotlin programming skills you need to get your first programming job, or perhaps a promotion to a more senior position.  And to do it in the shortest possible amount of time.

Do I need to learn 100% of the Kotlin language?

No!  To understand how this course can help you, there is a need to understand how programming languages are constructed.  The creators of these languages try and add every single feature they think someone might need, ever.

A large part of the language rarely gets used, and sometimes not at all.  It's the same with software.  If you have used a spreadsheet in the past, I'd lay odds that you use it for basic spreadsheet work, and you rarely, if ever go into some of the advanced functionality.  The basic functions of the spreadsheet are what most people use.

Imagine if you had to learn every feature of the spreadsheet program?  How long would it take, and would most of that information be useful to you?  Especially if you were learning it to get a job and that job only required basic spreadsheet skills.

Switching back to programming, if your goal is to get your first programming job, then why not only learn what you need to achieve that goal.  And worry about the other stuff if and when you need it.

That's what this course is all about - giving you the skills you need quickly without any fluff or useless information.


The course is aimed at complete beginners.  
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 about the instructors?

Your instructor Goran has been a software developer for over 14 years (12 commercially), creating Desktop, Web, and Mobile applications during this time.

He is a fully certified Java Developer (Java Oracle Certificate Associate programmer Java SE 8) and have a lot of experience with Java, Kotlin, JPA, Java Enterprise Edition, Spring, Spring Boot, Maven, Gradle, and JavaFX.

In addition, he has been heavily involved in game development and frameworks used to create games. He is also a Unity Certified Expert Programmer.

Here is another comment from a student in one of Goran's Udemy courses.

"Amazing , above expectation. All lectures are supported with essential examples showing the secrets of Java.I think I understand everything that Goran explains.I would really like to ask him a question, but for now I just understand everything. Very clear and precise instructions on what and how it happens.Goran reveals tricky questions that the examiners like to ask in the exam. Still, we are all here to prepare so well that we pass the exam with a minimum of 80 %, why not 100 %. I believe in myself and my own strength.Great job on making it halfway!I am keep learning!I love Udemy." - Valentin G.

What about if you have questions?

As if this course wasn’t complete enough, Goran offers  full support, answering any questions you have 7 days a week (whereas many instructors answer just once per week, or not at all).

This means you’ll never find yourself stuck on one lesson for days on end. With his hand-holding guidance, you’ll progress smoothly through this course without any major roadblocks.

Student Quote: "This is one of the best Unity and C# courses I've done on Udemy, and I've done a lot.

I initially didn't bother with the C# lectures since I've been programming with C# since 2003, but I decided to go back over the list of lectures after finishing the Game Development sections to see if there were areas of C# I wasn't 100% sure about, since it's continually changing.

I found the C# lectures I watched were all excellent. Goran is very good at explaining the more complicated C# topics, and I learnt a lot from them and came away feeling like I'd learnt a lot from them.” - Keith L.

There’s no risk either!

This course comes with a full 30 day money-back guarantee. Meaning if you are not completely satisfied with the course or your progress, simply let the instructors know and they will refund you 100%, every last penny no questions asked.

You either end up with Kotlin skills, go on to develop great programs and potentially make an awesome career for yourself, or you try the course and simply get all your money back if you don’t like it…

You literally can’t lose.
