Question

Given the following Groovy code switch statement:

def vehicleSelection = "Car Selected: Toyota"

switch (vehicleSelection) {
   case ~/Car Selected: (.*)/:

      println "The car model selected is "  + ??[0][1] 
}

Is it possible to extract the word “Toyota” without defining a new (def) variable?

Answer 1

This is possible using the lastMatcher method added to Matcher by Groovy:

import java.util.regex.Matcher

def vehicleSelection = 'Car Selected: Toyota'

switch( vehicleSelection ) {
   case ~/Car Selected: (.*)/: 
     println "The car model selected is ${Matcher.lastMatcher[0][1]}"
}
