Kotlin: How can I print only string elements from this list !?

Question

My code :
fun main(){
var myList = {"ABC", 42, 100.0, "xyz", "123"}

// Now what should I do to print String elements !?
}

I tried with lambda function, but couldn't find a way.

Answer 1

Gotcha, I just only need to add this :

myList.filterIsInstance<String>().forEach{
Println (it)
}

Answer 2

First of all u need to to use listOf() function, to create the list u want to create in ur question, and then u can easily use filter and forEach method to do this thing, see:

val myList = listOf("ABC", 42, ...)
// this will make List of type of class Any

// Now im checking if the element is String or not, and then printing it

myList.filter{ it is String }.forEach{
println(it)
}

Hope this helps u.
Keep coding in kotlin!!☺👍

You could do this as well.

for(element in myList){
if(element is String){
println(element);
}
}
