Kotlin Newbie To Pro - WHEN - Part 15

[@viktor-leskov]

When expression its most beautiful switch implementation i`ve ever seen

[@younesscoder]

Thanks dude for the tutorial This is my solution: fun main() { val country = readLine()?.lowercase() when(country) { "india" -> println("Namaste") "usa" -> println("Hello") "russia" -> println("Privet") "germany" -> println("Hallo") else -> println("I don't know that") } }

props for making this on Christmas you are truly a legend.

Thanks for the tutorials man? Finished a playlist of yours in 2hrs 😊

Are u sure that it is a good way how to learn programming? I do not think so...

​@pranavchaturvedi2452 what kinda progress you did after this series! It'll be so helpfull

Vanakkam! Love from India! A bit of gen knowledge: Hindi is spoken only by 40% of Indians. India has 22 official languages. Thanks a lot for these awesome tutorials.. I'm loving it!!!!!!!!!!

[@toystoryscarymovie-forkids3323]

thank you phillip but i believe the last question didnt reflect the assumption that the values 0 and 1 already existed in the list. it suggests an empty list question where entering a number >1 is the only input to the list

Thanks for this video, my answer for this homework stay bellow. I don't know it is the best answer, but a cant do it in this form fun main() { println("Where are you from?") val country = readlnOrNull() country?.let { country -> sayHello(country.lowercase()) } } fun sayHello(country: String) { when(country) { "india" -> println("Namaste") "usa" -> println("Hello") "germany" -> println("Hallo") "russia" -> println("Privet") else -> println("I don't know that") } }

[@nicolasvantsis6166]

Hi, for the solution of the first exercise maybe it's easier to do this: println("The 5 numbers in reverse order are:") for (item in list.reversed()) { println(item) } Because we saw this method in the previous video.

[@PhilippLackner]

That's easier, but less performant because you need to reverse the whole list and then print it. In my example we only print it because the index starts at the last number and goes down. But this series is not about performance, so your solution is perfectly fine, good job 👍

[@nicolasvantsis6166]

@@PhilippLackner Ok, thanks. For me it's better to learn the best solution (the one that gives the optimal performance) from the beginning.

[@ruhiyatrp6359]

thank you Philipp, i really love your tutorial, it very simple to understand... //Homework 1 println("Where are you from ?") val country = readLine() val x = country?.toUpperCase() when (x) { "INDIA" -> println("Namaste") "USA","GERMANY" -> println("Hallo") "RUSIA" -> println("Privet") else -> println("I don't know that") }

It is similar to switch case 😅

[@Ilamarea]

You can use boolean conditionals and other variables with a when statement, but then you need to repeat the variable: when{ age > x || age in 5..17 -> println(" ") age == 18 -> println(" ") age in 19..20 -> println(" ") } The important note is that the when statement will execute only one of the expressions and it will always be the first that matches the condition.
