Program to remove all whitespaces from the string in Kotlin

In this program, at first, we are reading a string and them replacing all whitespaces using the replace() function.

package com.includehelp.basic

import java.util.*

//Main Function, entry Point of Program
fun main(args: Array<String>) {
    // InputStream to get Input
    val scanner = Scanner(System.`in`)

    //Input String
    print("Enter String : ")
    var str = scanner.nextLine()

    //Replace character with Empty String
    val newStr=str.replace("\\s".toRegex(),"")

    //Print String after Replacement
    println("String after Removed WhiteSpaces : $newStr ")
}

Output

Run 1:
Enter String : Hello includehelp how are you ?
String after Removed WhiteSpaces : Helloincludehelphowareyou?
---
Run 2:
Enter String : Covid -19 [pandimic spread all over the world
String after Removed WhiteSpaces : Covid-19[pandimicspreadallovertheworld
