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) {
// 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


输出量


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
