consider editing your videos and planning out what you want to say before saying it. you speak very slowly and say uhh all the time.This couldve been a 10 minute video.
Thank you so much for this! This is the best tutorial I've seen thus far on youtube after all these years
Ugly ass color and/or font settings ... jezus ... i use light too but thaat looks to much noooob. contrasts are totally off too..
thx🖐
Dude this is so amazingly helpful.
Use dark mode for fucks sake
Thank you for making this crash course. It was just what I was looking for (while ramping up on a Kotlin project, and being an absolute n00b to the language)
Thank you for making a concise no fluff tutorial.
Excellent Tutorial! As a seasoned Java developer, I found it exciting without the fluff.
Thanks! This was much better than the extreme beginner tutorials explaining what a bracket is (useful, but not really my cup of tea after years of coding)
good tutorial, I just would like if you had used dark theme intellij
Waste of time
Nice tutorial. Thanks, alot.
Keep making more videos
You made everything crystal clear..Thanks for the help
Brilliant video, thank you. What is the best way to use multiple endpoints of an API without using a library?
😍🔥
1. Functions don't have to be in a class. 2. Functions are defined using "fun". E.g.: with main: fun main() { ... } (same as public static void main() in Java if not in a kotlin class) 3. Semicolons are optional. 4. val for final, var for changeable variables. val test = "string" -> final String test = "string" 5. Automatic type inference. Force with: var test: String = "string" 6. Nullable types. Use ? to make a variable nullable. e.g.: var test: String? = "string" 7. String joining with + works just like in Java, C# etc., but there are also string templates: println("Test ${5 + 5}") -> with { for complex expressions println("Test $name") -> without { for just referencing a variable 8. Arrays. Accesing is the same as in java. Creating with: val testArray = arrayOf(1, 2, 3, 4)
Thanks sir!
If you get 403 for connection.getResponseCode(); Just type: connection.addRequestProperty("User-Agent", "Mozilla"); You basically just need to authorize yourself for the website. Most websites have this security.
even the first second already looks completly different and makes this tutorial outdated. In create new project there is no such thing as Kotlin stuff you showed. And src folder is missing, ok I created it. But then I can only create .kts or .ws.kts files, but no .kt file ........
The software part might be different, but everything regarding code (which is the important part anyways) is the same.
Enjoyed your video but had to stop halfway cause I cannot keep straining my eyes, do well to increase the font next time
Danke
Nice tutorial. Is there a part 2 for it where you explain the advanced features ?
Perfect at x2 speed.
You have a very understandable and simple English and cool explaining ability! Thank you!!!
Gracias muchas gracias >:,3
Mate, what you call an "immutable variable" has a simple comprehensible name - it's called a CONSTANT. Immutable variable - variable that doesn't mutate, variable that doesn't variate - that's an oxymoron, how did you even come up with this? A CONSTANT - that's what it is.
Nice class.. just increase a font bit
is there a way to do it without the org.json dependencies
perfect/ thank you for such a great tutorial
Thank you so much for making this video!
Excellent intro! Thanks mate!
Thanks a lot for your work , and your English help me to understand more than you think. Good luck, I like your video ♥️
27 minutes to read a json, dude i hate java
Great Tutorial, though the font size is way too small :(
thanks
What is 299 here?
Thank you for the great tutorial!
This is very helpful video. I searched lots of video about like that but i couldn’t. That’s why thanks a lot.
Excellent! Thanks for this.
Thank you! Nice job :)
how to use Put Request ?
Love u hogya
Thanks a lot for the excellent explanation
Joined a new team and needed to ramp up on Kotlin. This tutorial is really useful. Thank you to the creator :)
how can I make it so that the parse method returns an array or array list of the data that I want? I see that currently there is a String return type. If we did return a string, where would that go? How do I receive that in the main program?
The screen is kinda small.
but how to you get a usable output from the lambda method? Like an object array or something that you could manipulate further
Thank you very much , very helpful
