Hi all
i have a question about kotlin loop foreach
In Kotlin, is it possible for an instruction after a forEach loop to be executed before the forEach loop finishes its execution?
Thanks!

You could use forEachIndexed and perform some operations before or after the last iteration.

Thank's but I want to avoid check in every iteration if it is possible.

Only other option I can think of is to drop the last item, and then process the last item after the forEach.

I think my question was not clear .

val list = listOf(1, 2, 3, 4, 5)

list.forEach { element ->
    println(element)
}
println("Done")

with this code i want to know if the foreach is synchrone (compiler execute all print of foreach elements before printing done)?

[mkrussel]

Then yes, done will not be printed before all the elements in the list have been processed.

Thank's very much @Shahzad Ansari @mkrussel
