Kotlin Programming Fundamentals Tutorial - Full Course

[@josphatkariuki3906]

People like this gentleman give me HOPE in life honestly speaking.... Thank Ryan for this.

[@MarcMcRae]

One of THE cleanest, gargon free starts..brilliantly explained. I'm a hobbyist, so for me it's the fun of learning to make something elegant. Thank you for this!

[@jonathancheli5842]

really Ryan? no degrees? no certificates? you are the best teacher ive ever had ahhaa.. man..do you have any ... Kotlin course for more advance/complex projects? you rock with your work! you are super clear!!! and really professional! this course s been a blast!

[@sohailpathan1436]

Loved this tutorial :D My takeaways: /** * Maintain the architecture of your application so that it will become open for extension and close for modification. * Always separate your code logic from the UI part. * Dependency injection is something that every developer should use in their application. **/ Thanks

[@InaAgapito]

If you are watching this in 2022 and using the intelliJ IDE don't worry when you run the application and get an error. Try it: 1. Remove the parameters in the main; 2. Rewrite de val operatorSymbol to receive an input from user: val operatorSymbol = readln() 3. Run it! So now it' should work normally 😉

Today I'm starting this course without any programming knowledge. Exactly 2 years from now I'll come back and post If I still code.

[@templeOfChrist1994]

At 37:03 I was like Bro? Your not serious right now... You had me fooled but 39:15 is so true, I programmed a small application to take in user input to an Array in both languages and wrote a lot less code in Kotlin

[@Rin-qj7zt]

Some feedback: I have a problem with your version of the "learning by doing" method. Its incredibly hard to retain information for me procedurally. Some people are okay with that, they happily learn how to do things while being unaware of the function and purpose they use it for. Ive seen someone install a garage light. This involves punching a preprared hole in the light casing like a soda can. When they got to the nand when they got to the next one they reasoned that it couldn't be done because a joist was in the way. They said someone had to come in and move or modify the joist. I took one look at it and saw that we could just use one of the other two prefabricated holes. They were so used to procedurally doing the process that they could not adapt once something came up. They didn't understand what they were doing, they just know how to go through the steps. More to the point, i need to understand _why_ before doing. I need to make those connections. I also genuinely believe that learning why, and _then_ doing is much more effective than simply doing and trusting that you will explain things later. One thing at a time. Theres no reason to postpone the explanation. Nobody needs to write code they didn't receive an explanation for first.

Thank you freeCodeCamp and thank you Rayn for this vid

[@b.k4142]

I write my first elvis operator fun main() { var a = 5 var b: Int = 10 val max = if(a>b) a else b println(max) val max2 = if (a > b ?: a) {println(max)} else {print(b)} }

val name : string = "bob" is so confusing way of coding, why Kotlin didn't followed the same principle as java and c#: =

[@olajideoluniyi6125]

Evening sensei.I am a newbie in the coding world and I absolutely love your teaching method..I have a challange ,the first code did not execute (intellij).. error index [0] is is out of bounds for length 0.. Please do you have any socialmedia handle...Twitter especially. Thank you

[@DavidMadrigalHernandez]

Not the guy in the video, but I can help you with that: ` error: index [0] is is out of bounds for length 0` So, for starters, we have to know what this is referring to. In this case, it is talking about the variable "index", which judging by the [0] after it, is likely being recognized as an array (think of it as a list of values that the computers indexes (or counts), and can look for. The "[0]" says "Item in the array in position 0". Confusing at first, but keep in mind that computers start counting from 0, not 1 like we humans do. SO that translates to "item at the beginning of the list". Finally, the last bit, "out of bounds for length 0" is pretty straightforward: the item cannot be referenced because it doesn't exits. Basically, its saying "I can't find the item at the beginning of the list because I have nothing in that list to look at." Hope that helps.

[@baovu4062]

hope you fixed it already. If not, it is out of bounds because you didn't give it any argument. Ways to fix it: ----- Way 1 (you need to change arguments in configuration) : - In ItelliJ > Run > Edit Configuration > * If there is alreay a Kotlin configuration for Main.kt then add arguments for the app in "Program arguments". * If there is no configuration then Create a new one from template (Kotlin), name it, add "Main class" = Main.kt and add arguments > then Run --- Way 2 (run program in terminal as .jar and give arguments in command line ): - In IntelliJ > File > Project Structure > Artifacts > Add ( + symbol) > JAR > From modules with dependencies > Choose "Main Class" (if there is any class)> OK - Build > Build Artifacts - In terminal, locate where .jar file is (usually in out/artifacts), make it executable (for Linux: chmod +x file_name.jar) and run it with java (java -jar file_name_or_path_to_the_file.jar some_arguments)

[@TurtlesWithAutism]

go to your run configuration and then in the program arguments type in either + - * / and hit apply, then run the code again and it should work.

[@b.k4142]

I know it s possible to modifie object stored in val ! how about variable ? May be i think for variable we have mutable variable and immutable variable for collection variable.

37:43 How do you pass the / symbol when running java -jar chap_six.jar / ? I get an error Same problem with * symbol edit : Seems that you need to escape / with / java -jar chap_six.jar // >1.25 Still doesn't work with the *

[@jocharles57]

Four months late, but maybe it'll help others. I didn't have trouble with / but did with *. Surround the symbol with quotes on the command line: java -jar chap_six.jar "*" java -jar chap_six.jar "/"

Hey everyone! I am absolutely beginner and having some problem with runing my code in Android Studio. It works in the online enviroment but I don't know how to run it on my PC. I wrote it in a new Kotlin Script, when I run it the additional command bar pops up, I enter the command let's say "+" and then it shows an error mesage. I would really appreciate some help. Thanks in advance

[@hitec1691]

please use dark theme in the IDE. its easy on the eyes

[@JulienReszka]

You shouldn't stay in a dark room it's bad for your eyes. Light Theme is the best theme, it's adapted to good working conditions, with good lighting in the room.

[@aymansyria4303]

You can go to Preferences -> Kotlin Compiler or Preferences -> Build,Execution -> Compiler and add additional command line options

[@Osmanity]

Here you have some constructive criticism for educating purposes: The event driven part was really poorly "explained" (and many other parts as well), the way you jumping around is so confusing and not a good way of teaching, this whole video feels more like show off rather then educating... redo the video in the sence that you are teaching explaining the small stuff too, ask other some maybe family member that does not know how to code for video review and then you would se the holes you might have not notice to explain...

[@Osmanity]

where did the "good way of coding example of seperation of concern" go???, if you show bad way of coding show the other way of coding in correct manners...

[@Osmanity]

why do you not prove your code by simply running it and test it, dont just talk and talk show the result by testing, is that really so hard?
