REGEX AND SPECIAL CHARACTER

Question

Hi guys, I have a problem!!!!
I am using the java.util.regex.*, when I try use the special character, for example ' \w ' I get a error
Pattern.compile("\w123\w");
The compiler return to me that the \w character is not a valide, the output error are:
"illegal escape character".
What I need do to put this character in my regular expression and don't get the error?!!?
Another question, I use the feloow code
Pattern p = Pattern.compile("isc");
Matcher matcher = p.matcher("Giscard");
if(matcher.matches())
   System.out.println("MATCH");
else
  System.out.println("NOT MATCH");  //The resul is always this, why the regex don't match with my name?Thanks one more time.
Giscard

Answer 1

1)
Pattern.compile("\\w123\\w");To input a single "\" in a Java program you must enter two "\\".
2) read the javadoc
matches()
Attempts to match the entire region against the pattern.
So "isc" only matches "isc", not "Giscard"
You need to use find()
