How to pad a string on both sides in Scala

Answer 1

def padBoth(s: String, totalLength: Int, padChar: Char = ' '): String = {
  if (s.length >= totalLength) return s
  val padTotal = totalLength - s.length
  val padLeft = padTotal / 2
  val padRight = padTotal - padLeft
  
  padChar.toString * padLeft + s + padChar.toString * padRight
}

println("'" + padBoth("Scala", 10) + "'")
println(padBoth("Scala", 10, '*'))
