/*
> () in regex means captured groups.
> If regex="(A)(B)", group() or group(0) shows the entire matched string. group(1) shows the corresponding match to pattern "A" and group(2) shows the corresponding match to pattern "B".
> (?:)--Here "?:" is added after ( to mean that this is a non-captured group. means it is not stored within group(index).

------------"https?://(?:ww[w2]\\.)?([a-z0-9-]+(?:\\.[a-z0-9-]+)+)"------
Example: http://www.hydrogencars-now.com.uk.org/blog2/index.php
Required domain: hydrogencars-now.com.uk.org

> http
> s? means s may or may not be present just once.
> ://

> \\. denotes the original dot.
> (?:) denotes a non-captured group.
> (?:ww[w2]\\.)? means non-captured group to get www/ww2 followed by dot. 
    This may or may not be present just once.
    
> ([a-z0-9-]+(?:\\.[a-z0-9-]+)+) means required output. that is, group(1).
> This means required domain is of the form "word.word.word...." 
> Here each word may consists of letters, numbers or hyphen only.
> [a-z0-9-]+ means this word.
> (?:\\.[a-z0-9-]+)+ means the combination ".word", one or more times. that is ".word.word.word..."
> \\. denotes the original dot
