, or with String class constructor String()
.

The syntax to create an empty String using String constructor is

Main.kt
fun main(args: Array<String>) { var myStr = "" println("Is the String empty : ${myStr.isEmpty()}") }
Output
Is the String empty : true
In the following program, we will create an empty String using String constructor.
Main.kt
fun main(args: Array<String>) { var myStr = String() println("Is the String empty : ${myStr.isEmpty()}") }
Output
Is the String empty : true
