Java 9 Regular Expressions

Method - boolean matches(String regex)

This method attempts to match a given regular expression against the complete subject String and returns true/false, indicating whether the match is successful or not. The following are a few important points to note:

• Regular expression is applied against the entire String; there is no partial matching
• Regular expression does not need to be anchored using ^ and $, since it is matched against the entire input
• The equivalent of Pattern.matches(String regex, CharSequenceinput) method (will be covered later)
