Hello,
Seeing a tutorial about java.util.regex (I isn't Java programmer), find a
feature interesting for character classes. See below:

[a-z&&[def]]    d, e, or f (intersection) 
[a-z&&[^bc]]    a through z, except for b and c: [ad-z] (subtraction) 
[a-z&&[^m-p]]   a through z, and not m through p: [a-lq-z] (subtraction)

How about that?
