pattern property
Java style regex pattern. Do not include the typical /
at start or end of regex in some languages. Given an example your code is: 12345
the pattern to extract match looks like code is: (\\d{6})
. This will return an array of matches with the first matching the entire pattern and the subsequent matching the groups: ['code is: 123456', '123456']
See https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html for more information of available patterns.
