Watched the entire thing as I practiced in IntelliJ. Super helpful. This was my introduction to Kotlin and I cant say enough how simple you made it. Thank you so much Philip.
Great job! That was super informative. The only feedback I'd give, is that when you're declaring a variable of type String or type fun, to use slightly different naming conventions to avoid any confusion. For example, if you're declaring a String, avoid calling it "string" and if you're declaring a function to avoid calling it "function" It just made the lambda and generics section a little bit harder to follow is all. Other than that, this was a 10/10. You did a great job explaining some of these concepts!
Hey Brad, just wanted to let you know that I love your content man, please do some more videos on data structures and algorithms, I need some to ace my upcoming interviews ;)
@@TraversyMedia Thank you really much man, we appreciate it, I read many books and I am still struggling with some of them lol.. Keep up the good work👍
For anyone who finds there is no "File -> New -> Kotlin Class/File" option, you may have to mark the top folder (in the Project pane; with the project path next to it) as being the "Sources Root". Right-click the folder and use the "Mark Directory as... -> Source Root" option. Then the "Kotlin Class/File" option should become available from the "File -> New" menu.
great tutorial, I am a java developer newly entering to the kotlin programming and this covers kind of all the things for me. Thanks and keep up the good work.
For those in need, new version of IJ you go New Project -> select (under nodejs) JVM it is already an IDEA, and the rest is similar to his. As for creation of new kotlin files mark src as root folder by clicking right click on it and then select `Mark Directory as` and `Sources root`. Then in src->main->kotlin create new files by right click->New -> plenty to choose from.
This is an excellent tutorial for beginners to understand basic concepts such as functions if else if etc; as well as for people who have learnt all the advanced concepts before in java but have never used kotlin before and are now moving to kotlin for android dev.
Thanks so much for this, this has got me up to speed enough to make a start on the little project I'm working on! Quick note for anyone new to programming confused by the lambda function syntax around an 01:20:00, "function" and "string" here are just arbitrary names for those objects, not keywords. They could just as easily be anything else.
Damn,,, bro this is crystal 🔮 you have really explained everything to the extent that ,,, even those that do not have an idea what programming is ,can grasp everything... Thank you for this bro keep up💙🤜🤛🙏
Bro, you are amazing, I have been struggling with Android because almost all tutorials overcomplicate things, yet , you on the other hand, you make it so simple. Thank you, pal
You're an amazing teacher! All of the concepts were masterfully explained, and I grasped them almost immediately. I'll mess around with Kotlin a little to get a hold of its in and outs, and then I'll watch your video lesson on app development. Thanks again!
Awesome dude. I've been meaning to learn Java for a long time. I'm definitely going to be a new subscriber to your channel bud you did a great job on this one.
Thanks a lot! Very nice and thorough introduction. You pointed out some great little nuances about the language that already make me excited to get started. :) For extra credit, the final function you write -- the generic customCount() extension... if we want to be 'clean', we should rename the variable 'string' to something like 'type'. So, "for (type in this)" etc. It pays off to have your variables named properly ;)
@Philipp Lackner so the I (OR) is referred to as the PIPE symbol So II is the Double PIPE. Thanks for sharing your knowledge. Very clear explanations. You go further than most with the syntax and some edge cases and clarifications. Very helpful.
I've never written a single line of kotlin in my life yet I was familiar with everything in this tutorial (coming from a TypeScript background). That emphasizes the golden rule of "focus on programming concepts not the specific language, framework or stack"
This was great for me ! I am coming from Java and wanted to get on board with Kotlin quick, without the unnecessary fat which you can find in most of the other courses. Thanks a a lot !
I've had some trouble making a Kotlin project on the new IntelliJ IDEA 2022.2 version. You have to start with a general New Project, then select Kotlin for the langauge, select IntelliJ for build system, and also tick 'add sample code' to get it to work.
To be fair Java is catching up quite a bit in recent versions. So I'm not sure if Kotlin will ever replace Java or the other way around or if they just continue to coexist. It seems like Oracle accepted the challenge. Nevertheless it is a great achievement for Jetbrains to play at the levels of Google and Oracle. And their IDEs already wiped the floor with their competitors.
If you are not getting the empty folder structure as shown in the video, and the "Kotlin" selection [@8:30] shows additional options not shown in the video, from the "New Project" menu, try instead selecting "Java" -> "Kotlin/JVM".
Great Phillip, really great to see a german developer on the rise. Your presentation is inspiring, very clear and on spot. Hope to see myself in a similar position in some time :-)
Just to put it out there...I was not able to RUN the code initially...it just showed the 'EDIT CONFIGURATIONS' option. The solution was to just press RIGHT CLICK on "src" Folder ---> Mark Directory as ---> Sources Root.
Great video, but there's something missing: if you refer "there will be an error" - you can do one more step to show this error, rather then describing the error.... "see it once is better than hear it 100 times" Thanks again for the video!!!
I know this a general purpose video on Kotlin and not necessarily an Android app video (which is coming next) but I'd imagine the next logical step would be having someone on for a Swift tutorial, no?
@@TheRealLucifer-Morningstar I found there were two differences in what I was seeing and what is in the video. I posted potential solutions to both of them in the comments (sort by newest). HIH
3/16/2021; my version of IntelliJ does not have the same options; from installation as far as @10:43 I'm trying to follow along, but I cannot however, you are an excellent instructor and I approve of this video
If anyone got stuck with the Main.kt file, in IntelliJ 2020.3 (or whatever the version after the video's is), I had to put the file at src/main/kotlin/Main.kt
Thank you, Hali, for the effort you made, and your presence from the beautiful and beloved characters with explanation, and God increased you in his knowledge. I learned Kotlin Android and I went back to learning from the first to verify the information that I learned from the Arabs, so may God reward you with confusion because most of what we have learned is not complete, and thank you very much and good luck. God bless you
I am new to app development and I can see how this crash course can help me. This new version of Intellij IDEA will ask me to choose Target JVM version and Test framework when adding a new project. If you can help me out, that would be really amazing.
54:20 I guess I don't completely understand why are you writing it so differently for the isOdd function? Can the even and isOdd function be written either way?

Oh Wow. Just few hours ago I was searching for Kotlin tutorial, and here it is !
its amazing loud and clear, thanks to Brad for making its easy fr your million subscribers to easily find out about other great teachers.
This is the best kotlin crash course, I've ever found on youtube! Really good video for a refresher
Bro, you are amazing, I have been struggling with Android because almost all tutorials overcomplicate things, yet , you on the other hand, you make it so simple. Thank you, pal
Really loved the way he taught kotlin and explained everything so clearly.
Looking forward to his android crash course.

My advice on programming for the fellow wanna be programmers is this.... Consistency is the key and if i or he can! You can too
Ok

Same story, JS and Python before ;)
Coming from C++ and Python, same here
He explains interfaces like way better than a college professor.
Nice job Philipp! I'm intending to move from Java to Kotlin and I was looking for a nice way to dive in! This video just did the trick! Thanks really!
I've wanted to learn Kotlin for ages! Thank you so much, and a big thank you to Brad!
This was great for me ! I am coming from Java and wanted to get on board with Kotlin quick, without the unnecessary fat which you can find in most of the other courses. Thanks a a lot !
Kotlin is my favourite language of the ones I’ve used. Syntactically it is beautiful and it just makes sense.
Kotiln is currently my preferred programming language. Absolutely beautiful!

Your definition of the word Abstract is the first time its actually made sense. Thanks for that.
Wow 😍
Hi man, your videos introduced me to kotlin and android development. I hope you get featured in brads channel someday. Big thank you @coding_in_flow
Hey Brad, Thanks much for the course. It helped me significantly to jump start Kotlin.
If you are not getting the empty folder structure as shown in the video, and the "Kotlin" selection [@8:30] shows additional options not shown in the video, from the "New Project" menu, try instead selecting "Java" -> "Kotlin/JVM".
Oh my goodness thank you, I just spent the last hour trying to figure this out
I'm really glad that kotlin look 80-90% exactly same as JavaScript which will help web developers learn kotlin easily for native mobile development
Great Phillip, really great to see a german developer on the rise. Your presentation is inspiring, very clear and on spot. Hope to see myself in a similar position in some time :-)
Thank you, wish you the best with your channel! :)
Dumbstruck at how good and huge this channel has grown. Keep it up, Brad 🔥

Perfect introduction of Kotlin for begginners, thank you!
"Real programmers use dark theme" :). Thank you for this crash course, I learned a lot and it was fun. Keep up the good work!
This is such a big help! Thank you!
"Lamborghini, Penthouse, Rolex.... just a normal purchase for a programming TH-camr..." :D :D :D
This was fun... played with Kotlin a couple of years back and this is a good excuse to revisit it... might use it for adventofcode this year.
Thanks for this tutorial. It was exactly what I needed to gain a bit of familiarity with Kotlin quickly.
thanks for making me understand kotlin
I knew phlipp lackner from his channel and im happy hes spreading his knowledge on other channel :)
Very comprehensive Tutorial for a Java familiar Programmer. Good Job.
Great video, but there's something missing: if you refer "there will be an error" - you can do one more step to show this error, rather then describing the error....
"see it once is better than hear it 100 times"
Thanks again for the video!!!
Thanks for this channel. Now I understand Kotlin more where others channels overcomplicate all time.
Your content is crisp, Thanks a lot for that, keep it up.
This video really got me going on kotlin and helped me understand it. Thanks
Very good video for beginners I really liked the examples and the way you explain everything. Keep up the good work.
Best real world explanation of abstract class i ever heard.
very helpful, thanks!
Thank you for this crash course and we need more videos like this.
omg i was thinking of learning kotlin and this popped up, i think its meant to be
If you talked about it next to your phone or computer mic big brother google must have heard it hahahahaha

I like this video because he almost explained every necessary concept in Kotlin
Very informative. I got everything except for the lambda part but that's not a big issue. SHOKRAN!
Done watching the full video of this tutorial! Thank you sir! :)

Having the same issue, when I right click on .src I can't create a .kt file. I can create a .kts file though.
This was a great crash course, thank you very much for putting in the effort :)
wow! I have been waiting for this course!
This is right on time for something I'm working on. Thanks
The best crash course i could find , thank you
fantastic video! :) thank You for putting it together!
Thank you for your amazing explanation .I am beginner but i am fully satisfied with your class.sir please keep on
The JDK has moved and intellaJ has changed. Could you do a modern video ?
Thanks a lot. One of the best in TH-cam.
I'm not good at English but you are so amazing but Your explanation is really simple
thank you so much
Thanks Phillipp it was an awsome course!
If anyone got stuck with the Main.kt file, in IntelliJ 2020.3 (or whatever the version after the video's is), I had to put the file at src/main/kotlin/Main.kt
Up you go!

- Kotlin not configured
- No option for .kt
- Won't run "Hello World!"
- Red everywhere.
I love code :)))))

Well done. Very precise for beginners!
Very good introduction to Kotlin
kotlin all the way.Would love to learn more on ktor language
Is Kotlin easier than Java with a bit of modern day syntax?
I wouldn't say learning Kotlin is easier or harder than Java, but once you know it, you can do things easier than in Java and in less code
Awesome video man, thanks a bunch!
I love Kotlin!!!
