regular expression in java question

[Chen Yang]

Hi there,

How can i make the Pattern.compile as character '*' and '(' ?
I check the API, and it says:

\cx The control character corresponding to x

And if I write like this:

Pattern p1 = Pattern.compile(".*\\b\\c(\\c*\\b.*");
Matcher m1 = p1.matcher("(* ");
System.out.println(m1.find());


It returns false. Plez help me out with this, thanks in advance.

I check the API, and it says:

You mean you want * and ( treated as literal characters rather than as
magic Regex commands, right?

You must precede them with a \. Since \ has magic meaning in Java
Strings, it must be doubled. So you would say \\* or \\(

See http://mindprod.com/jgloss/regex.html for more details.
