Idiomatic way to generate a random alphanumeric string in Kotlin
Solution 1:
Since Kotlin 1.3 you can do this:
fun getRandomString(length: Int) : String {
val allowedChars = ('A'..'Z') + ('a'..'z') + ('0'..'9')
return (1..length)
.map { allowedChars.random() }
.joinToString("")
}
Solution 2:
Lazy folks would just do
java.util.UUID.randomUUID().toString()
You can not restrict the character range here, but I guess it's fine in many situations anyway.
