Create A String



In [1]:

    
// Create a string value
val text: String = "Lt. Steve Miller will be leading the attack."

Create A Regex Pattern



In [2]:

    
// Create a regex pattern for a name
val find_steve = "Steve Miller".r

Replace Anything That Matches That Pattern With Something Else



In [3]:

    
// Replace all instances of the pattern with a different name
find_steve.replaceAllIn(text, "Peter Jackson")









    Out[3]:





Lt. Peter Jackson will be leading the attack.
