Your speaking accent is so clear and easy-to-listen. As an non-native English speaker, I really understand what you are explain. Thank you for your lesson for us.
I'm so happy to hear you've been able to follow along and have found it useful 😀
Same this great job
Arie, please share it with millions of Indian bloggers, who speak English so terrible that it impossible to listen to that Udemy courses.
@@eugenenovikov671 I think he is an Indonesian not Indians
@@jessica-tv6ep no matter, they all speak undistinguishable if such word exists, i dont buy their courses cause it impossible to understand
This is amazing, really condensed a lot of information in less than 3h. One of the best programming tutorials that I've followed, Thank you
Man, you've done really great work. Great material, normal micro, awesome voice. And, despite the big deal of subscribers, no ad. I wanna say that we appreciate your work and thanks.
This basic overview was simply amazing.
Thanks, Nate!
You're very welcome! Thanks for watching
I have watched many “tutorials” explaining programming languages. By far, yours is not only an actual tutorial, but a very good one indeed!
It has all the core values a good tutorial must have: starts from the basic elements and slowly makes its way up the ladder into more complex functionality, it is slowly and carefully explained with simple examples (I have seen people using frameworks for a graphic user interface just for a hello world in a new language...) and shows the result for both the valid cases and invalid cases as well as ways to tackle common problems that may appear.
I had zero knowledge about Kotlin walking into this tutorial and I have quite a good idea of how it works now by only watching the video (when I start actually writing code, this will be consolidated) also thanks for all the Java analogies, they really helped understanding some of the last concepts.
11/10 on this tutorial, 11/10!
Seriously.....? Actually even I have just started my course so before starting this video I decided to go through the comment section for checking how good this video is because I have zero knowledge about kotlin so thanks a lot for your review it means a lot for me.......
Hi Nate, your tutorial is awesome! It's just what I needed - clear and simple explanations, going from easy to more complicated stuff and on top of it your accent is very easy to listen! Thumbs up!
Happy to hear you enjoyed it 👍
A very concise and flowing explanation where everything comes up in the right moment and at the right place makes of this explanation a really nice introduction to this new and beautiful language. Thank you! The only section where I got puzzled was that concerning the sealed classes, but I hope everything will go clear giving it another look.
Thank god you exist !! World would have been difficult place to live without you .
Best tutorial to start with learning kotlin, crisp, no ad, more practical. thanks
😀👍👍 Glad you enjoyed
I did this course for 4 days with interval of last session with 1 week ... Damn ... That was the longest motivation to learn some language .. I'm comming from python and the lucid syntax of kotlin really really makes me learn more of it
glad to find this course, there are so many courses aout there about android development using kotling without really digging in or teaching the basics of the language that you end up understanding NOTHING of what one is doing!!! Thank U SO MUCH!!!
I can't believe how easy Kotlin really is. Coming from someone who codes in Go and Javascript, this language is like the best combination of both worlds.
Have you tried .NET 7? It's easier than all the languages you mentioned.
I viewed it as a combination of Java and Python
Hello, thanks for the awesome tutorial. I love the way you speak slowly and clearly so even if I am not a native English speaker, I can understand everything. Plus your tutorial really helped me out with an intro to Kotlin. Great job
Who else is learning Kotlin for Android development?
i am learning it to help with uniciv
No, I am learning how the "SkIDE" works.
@@JohnJohn-nu7tr how was it? :D
And now I submitted pull requests!
I am learning it newly
You are awesome! Best tutorial on Kotlin there is out there ! Thank you!
I was looking for a good intro to Kotlin. This is perfect! Thanks!

Thanks for this. Definitely one of the better tutorials I've seen on Kotlin. Well done.
Glad you enjoyed 👍👍
Very good tutorial. Concise and Clear. This is my first tutorial on Kotin and I would to thank you for putting this together and allowing free access to developers new to Kotlin.
Glad you enjoyed it! You can find more Kotlin tutorials on my TH-cam channel as well
This is the best free Kotlin tutorial I have ever seen. Well done! I don't know what's up with the 26 dislikes... how could you possibly dislike this?
😀. That's very kind of you to say. Glad to hear you enjoyed it 👍👍
Excellent tutorial. I'm quite excited about this language.Never looked at it before but it looks good
🙂 I'd encourage you to give it a look. It's really quite nice, and can be used in a variety of domains
Have just finished this course. It's very good for getting started with Kotlin. Many thanks to the author!
You're very welcome! Glad it was helpful 💯
Thanks for the tutorial! I thought I could do it all in one day, but it toke me 3 days to do it
There's a lot to take in. Doing it all in one day would be a lot for anyone. Great job on sticking with it and making it through! 👍👍
Thank you for the content. Straight to the point, well explained, and no fluff.
Glad you enjoyed 👍
Just finished watching and coding. The tutorial is simple and very neat. All the basic concepts which are needed are covered. Thanks a lot, mate :)
You're very welcome! Thanks for watching.
you became a programer in kotlin
I wish you would put ads, you deserve compensation for your great work, I would gladly watch the ads.

People are allowed to do stuff for free and just to give back to the community lol
Great video, compressed and displayed in clear and concise way, thanks a lot!
You rock. Theres so many things kt can do, it made me sleepy just seeing all your examples. It gets complex, kinda hard to read a times. But you rocked it
Definitely a lot there! Thanks for sticking through it 😀 Hope it helped 👍
ppl having issues on SDK / JDK:
I had the same issue but that is bc when you were creating a new project you selected Kotlin but instead choose Java then select Kotlin/jvm. This should set up the same environment as the presenter:)
Thank you for saving few hours I was going to spend figuring out IntelliJ and my sanity
This is EXACTLY what I needed. Thank you.
Glad to hear it... Hope it helps 👍👍
Such a great Vid! Thanks! I look forward to more content about Kotlin!
You've covered so many topics others have not. This is really well done. By referencing how it's done in Java, it really speeds up the learning process for experienced developers.
What a wonderful language, everything is thought through while designing the language constructs. Highly recommended course. Beautifully explained. Thank you.
As a non native speaker and not even fluent I can say: Your way to speak is very clean, concise and easy to understand
happy to hear it!
Great tutorial dude, also the content section about the course is amazing
This tutorial is close to the perfection! I can't point out even a small improvement in this! Thanks much!!
@1:41:59
just because we wanted to use the same function defined in the interface
which takes in a parameter in the form of its read only property aka "val"
we need to make multiple inheritance and override the property in the respective implementing classes
Tutorial is precise, understandable and beautifully presented. Thank you so much 😊🙏🏻
You're very welcome! Glad you enjoyed it!
Just started learning it, what a beautiful language
An excellent tutorial for an excellent language. Thank you for this video! It really managed to explain a lot in a short amount of time.
this video is the best tutorial that I have ever seen, thank you so muchhhhhhh
Wow! very high praise. I'm happy to hear you found it useful!
I got tired of searching how to code videos so now im trying it for real!
😀 Good luck 👍
@Que_Rico Learning a language on its own likely won't land you a job. I think it's more helpful to think about what you can build with a language. Learning Kotlin can enable you to build a variety of things that likely have different demand in the job market. If you learn to build Android apps with Kotlin there are many jobs out there. Writing backend code with Kotlin could help find a job as well. I'd encourage you to think of what types of projects you want to work on, then determine if Kotlin is a viable tool for that project. If it is, and there's a demand for that work in the job market, then Kotlin would definitely be a positive step towards landing a job.
Your course content links is the most considerate idea especially for learning. One can go back again and again until the tricky topics are well understood. I would also like to say thank you sir.
😃 👍👍
Excellent! Thanks! Great tutorial. I'm convinced ;) I'll spend a bit of time getting the hang of Kotlin to save time in the future.
Love how you keep mentioning the differences to Java. Had you on 1.5x speed for the first half, then switched back to regular ;)
Kotlin is really similar to python and is really easy, very good explanation Nate sir, you are a legend :)
so thats good for me because at first i was trying to go with kivy given that i kind of know python but ive heard its better to go with kotlin if i want to make proper app
it is just so good, i do not speak good englisch, i watched it in 2x speed and could still understand everything. thank you :))
Glad to hear you enjoyed it 👍
hahaha
Finally some proper content for beginner developers! Thanks!
My first time doing Kotlin and you made it an easy journey for me - Thank you :-)
This is a great course!! if you know any C++/Java everything just makes sense
Very true. Once you know 1 language, it becomes a whole lot easier to understand others.
Hey Nate, great tutorial. Was really easy to follow along and you did a great job explaining the concepts. Thank you!
You're very welcome! Glad you enjoyed it!
It is a big one to get started with Kotlin, thank you very much.
Very informative straight to the point tutorial! Thanks a lot Nate ;)
You're very welcome 👍
Great clear steps and a very logical approach. Thank you for your hard work with this.
Great video. I'm just under an hour in so far and coming from a C# background and I am finding your tutorial so clear and easy to follow that I am considering learning Kotlin now to have it as another tool in my commercial development toolbox. As others have said you articulate ideas clearly and should really be doing tutorials professionally. Have you considered signing up with pluralsight and become a tutor on there?
Thank you so much. That's a great compliment. I actually am working on a Pluralsight course right now.
Man your way of teaching, your voice is tooooo good. I really appreciate it.♥️
Thanks for watching! 😀
Thanks for the lucid explanation, a great intro to Kotlin.
Tq soo much i waited for ur video for so long i love u for making kotlin at right time tq sooooo much
I hope it's helpful for you 😀 👍
@@goobar yes sir it is and tq again u r a life saver
It seems that I've fallen in love with Kotlin. Thanks for such easy-to-understand tutorial!
Very happy to hear you're enjoying Kotlin 😀👍👍
There are no words to thank guys like n8ebel... they make our life so much easier. I need to learn Kotlin quickly for job purposes and it's like a boost to learn from a video like this, without the need to read an entire book or documentation/articles. Books, docs, and articles will be very important, in the future, but the get an entire overview of the language this is awesome. I can't imagine the time that he, and guys like him, spend to makes this happen. Thank you so much!
You're very welcome! I'm glad to hear it helped. I agree with you. It's amazing how many people out there are willing to help us all learn!
Very very nice Kotlin introduction. Neither too basic nor too complex. 👍
Yea, Nate 😎
Yea, Florian 😎
Is it me, or does Kotlin just seem like a language that satisfies the unknown need all developers have deep down
haha. I can't speak for others, but I've certainly enjoyed learning and using it
Good luck
The code reads not too different than Python with { } instead of tabbing and camelCase instead of snake_case. Not quite as concise as python but far better than regular java.
_this one sparks joy_
Java is better
Thank you! This was a great tutorial with a detailed explanation.
So happy to hear that!
Great tutorial Nate! Keep it up!
Really it`s an amazing tutorial I loved it every minute in the video is important but I see that u should mention that this tutorial is for anyone who has at least some experience about any oop language like java
Yeah. That's a very fair point. The target audience should have been called out more clearly
Wao... Amazing language for app development.💐💐💐💐💐💐💐💐💐
Not only
Sadly it cant compile as exe
@@sefovsky Sure you can... target Kotlin native. Throw Android Studio to the trash bin
Kotlin native has been measured slower than Kotlin JVM. Which is sad :(
@@sefovsky Eh, just use the JVM. It will give you support for both Java and Kotlin.
you and your team are doing a great work
Your explanation was excellent! Thanks for the tutorial.
I find it interesting that with Kotlin they moved away from the pure class style of Java, and moved to a C++ sort of mixture between procedural and class programming.
I bet you have not try type script/JS, they created a whole set of functional programming features set aside the object-oriented methodology. When I working on a 2-year-old project, I feel like I need to rewrite every single component. And what do you think c++ is moving toward? My understand is Python...
I can relate to this!! As soon as I saw fun main() { println() } it made me immediately think of C++ for some reason. Glad i'm not the only one,
@@jgdevelops8440lool same😂
This tutorial is great for people who have already worked with Java, but not really for beginners or people who know a language with a very different syntax (like Python). I recommend explaining some things like getters, setters, maps, and when-statements in further detail (or at least put a disclaimer at the beginning of the video that this requires prior knowledge on some of these topics).
yes, it is!
Great job man, really a great video to start with!
Hi, Thanks for such a wonderful tutorial..Just cleared some of my kotlin doubts. Hope u add couple more interesting kotlin fundamental
videos
Why tf don’t you put ads your content is so great!!!! I’m happy I found you 😭❤️
Thanks for the tutorial. Your explanations are easy to understand. I hope future tutorials will have a better sound quality. You sound a bit muffled in this one.
Really interesting, simple and gives so much basic knowledge about kotlin, very well done , thanks a lot 👏
Absolutely Amazing Content! 5 Stars
Well it was not my plan to learn Kotlin, I itend to learn Java, but this course is so good, I don't have other choice hahaha
Haha. You could always learn both 😀
Java sucks
I tried Java too...still stock on a darn tree exercise lol so this is encouraging.
Is this dadjoke popular? "Declaring functions in Kotlin is fun" :D
It is with me 😀. I gave a conference talk once titled simply "fun() talk"... it was all about functions it Kotlin
🤣🤣🤣
fun begins ()
It is where fun begins
@@Sunny-zh6go yep the Fun also a funtion so to make something fun it must funtion properly 😂😂
sometimes it's private fun...
mind blowing tutorial!! fallen in
😀 👍👍
Great work! The high order functions examples was really good
Glad to hear it
Within the first 30 minutes, this seems like a blend of Java and C++. My only complaint, if you could say, is it seems like the compiler does a looooot of work, I would like to see examples of how the compiler expands things and see what is actually going on. I imagine there is somewhere to see that in android-studio
The syntax also has a decent chunk of Pascal in it.
Any compiler does a looooot of work. What is the problem with that?
C for microcontrolers would be interesting to watch.
Thank you so much for such a detailed tutorial.
amazing sir keep it up and we are waiting for your more tuts
UPDATE:WORST TUTORIAL FOR BEGINNERS THE WHOLE VIDEO IS ASSUMING YOU ARE A JAVA EXPERT. I DON'T LIKE JAVA THAT'S WHY I AM LEARNING KOTLIN IN FIRST PLACE.........
When I first watched it with no prior programming experience, I didn't understand a thing. Now after having learned OOP, Array, Classes, Main function, fundamentals, etc, from Python, Js, React, I finally understand it. It is a very good tutorial but in my personal opinion it is a too fast paced. But still a great tutorial for Kotlin. To anyone watching this without any programming experience or knowledge please try to learn the fundamentals like "if-else" Before watching this video
Make a video on Android studio
Omg what an awesome tutorial! Thanks a lot
Great tutorial, thank you!
Hey Nate, awesome course! What is the name of the IntelliJ theme/plugin used in this video?
Found it. For anyone looking for this, it's the Material Theme UI plugin.
Looks like you found it 🙂. Using Material Theme UI plugin with the Night Owl editor theme I believe
@@goobar You're right, but it is version Darker. You can see theme name on bottom right of his screen. I prefer Deep Ocean.
Thanks
Please upload TCP / IP course
Thank you for this wonderful instructive video! Appreciate your efforts! :D
Glad you enjoyed it 🙂👍👍
I can't really get started because my intellij are very different from yours
Thank you very much for such a great tutorial!
I've learned Java (love it) and to be honest, I'm a bit terrified with that amount of flexibility in Kotlin. All I can think about is "That
could be such a mess".
The flexibility definitely has potential to be abused. I think a good rule of thumb is to take advantage of features to make the code concise, but not so concise that it's no longer easily readable.
the flexibility is mind blowing........
Phew! That was a lot! Thanks so much for doing this!!!
You're very welcome! Hope it was helpful!
This is beautiful. It looks like someone took the best features of C# and added them to Java, and Kotlin was born.
I do believe there are c# influences from JetBrains having worked on c# tooling for years and wanting to pull in the best parts of various languages.
I'm really confused, I think some of the things in IntelliJ are different for the newer version, please could you make an updated tutorial.
There is no Kotlin in the IDE, only Kotlin Multiplatform. Fell st the first hurdle.
@@funky-twig oh ok
Thank you for your great tutorial. However, I wonder why the Chinese subtitles have so many English words. It is better to remove this poor Chinese subtitle.
I think the subtitle is from your end because I am getting english subtitles only........there is a subtitles option u can go on that choose ur subtitles or u can even switch off subtitles.......
Exceptional, thank you!
Greatly explained! Thanks for sharing such great teaching skills!
You're very welcome! Glad it was helpful 👍👍
