How to match the first word after an expression in a string using RegEx with Scala

Answer 1

import scala.util.matching.Regex

object MatchFirstWord {
  def findNextWord(text: String, expression: String): Unit = {
    val escapedExpr = Regex.quote(expression)
    val pattern = new Regex(s"$escapedExpr\\s+(\\w+)")
    pattern.findFirstMatchIn(text) match {
      case Some(m) =>
        println(s"The first word after '$expression' is: ${m.group(1)}")
      case None =>
        println("No match found!")
    }
  }

  def main(args: Array[String]): Unit = {
    val text = "The quick brown fox jumps over the lazy dog."
    val expression = "fox"

    findNextWord(text, expression)
  }
}


 
/*
run:

The first word after 'fox' is: jumps

*/
