.matcher(String) makes a new Matcher object for the given string, which defines some functions to apply the regex to the string. this includes finding the pattern in the string and scrolling through every occurance (.next and related methods), or checking if the pattern matches the entire string (.matches)
so for every string, you're creating a Matcher, and checking if the Matcher says that the pattern matches the entire string
