This tutorial was inspired by the awesome Scala Cookbook.

Create String



In [39]:

    
// Create a string value
val text: String = "27 aircraft"

Create Regex Pattern



In [40]:

    
// Create a regex with two pattern matches (one number and one word)
val pattern = "([0-9]+) ([A-Za-z]+)".r

Extract Substrings That Match Regex



In [41]:

    
// Apply the regex pattern such that each of the two pattern matches is assigned to a seperate value
val pattern(vehicle_number, vehicle_type) = text

View Output



In [42]:

    
// View the value
vehicle_number









    Out[42]:





27



In [43]:

    
// View the value
vehicle_type









    Out[43]:
