Kotlin – Convert char array to string

To convert a character array to string in Kotlin, use String() constructor. String() constructor can take a Char Array as argument and return a new string formed with the characters in the given array.

String(chars)

In the following example, we take an array of characters, and convert this character array to string using String().

Main.kt

fun main(args: Array<String>) {
    val chars = charArrayOf('a', 'p', 'p', 'l', 'e')
    val str = String(chars)
    println(str)
}
