Check if a string is blank or doesn't exist in Scala

Question

I have an Option[String].

I want to check if there is a string exists and if it\'s exists its not blank.

def isBlank( input : Option[Strin         


        

Answer 1

This should work as well since filter of an empty Option results in an empty Option

def isBlank( input : Option[String]) : Boolean =  
   input.filter(_.trim.length > 0).isEmpty
