Kotlin – Iterate through all files in a directory

We shall use the extension functions  of java.io.File : walk(), walkBottomUp, walkTopDown()  to generate kotlin.io.FileTreeWalk on which we use iterator to traverse the directory and its contents. The functionality of the three functions is almost same except the order in which they iterate through contents.

Kotlin Examples – Traverse or iterate through all files in a directory using Kotlin

Traverse or iterate through all files in a directory using Kotlin - Kotlin Example - Kotlin Tutorial - www.tutorialkart.com

walk() – using java.io.File.walk()

walkBottomUp() – using java.io.File.walkBottomUp()

walkTopDown() – using java.io.File.walkTopDown()

Conclusion :

In this Kotlin Tutorial, we have learnt to use java.io.File.walk(), java.io.File.walkTopDown() or java.io.File.walkBottomUp() functions traverse or iterate through all files in a directory with the help of Kotlin Examples.
