Kotlin – Check if File exists
Kotlin – Check if File exists : In Kotlin, to check if the file already exists, use File.exists(). File.exists() returns a Boolean value. It returns true if the file exists and false if the file does not exist.
Example – Check if File exists
In the following example we shall check if the a file “data.txt” exists.
import java.io.File fun main(args: Array<String>) { val fileName = "data.txt" var file = File(fileName) var fileExists = file.exists() if(fileExists){ print("$fileName does exist.") } else { print("$fileName does not exist.") } } |
data.txt does exist. |
