How to include symbol of the end of the line ("\n") in regexp

i have regular expression which need to cover multi lines(delete comments from pascal file)

\(\*.*?\*\)|\{.*?\}|\/\/(.*$)

This will match literally everything, including newlines:

Pattern regex = Pattern.compile("[\\s\\S]*");

You are looking for the Pattern.DOTALL flag. Pass it to Pattern.compile like so:

Pattern p = Pattern.compile("regex", Pattern.DOTALL);

You can also set it in the regex with (?s), like: "(?s)regex"
