How to replace multiple spaces in a string with a single space between words in Kotlin

Answer 1

fun replaceMultipleSpaces(str: String): String {
    // Use a regular expression to replace multiple spaces with a single space
    val result = str.replace("\\s+".toRegex(), " ")

    // Optionally trim leading and trailing spaces
    return result.trim()
}

fun main() {
    val str = "   This   is    a   string   with   multiple    spaces   "
    val output = replaceMultipleSpaces(str)

    println("\"$output\"")
}

   
      
/*
run:
   
"This is a string with multiple spaces"
  
*/
