Replacing text using regex

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MainClass {
  public static void main(String args[]) {
    String regex = "(\\w)(\\d)(\\w+)";
    Pattern pattern = Pattern.rupile(regex);
    String candidate = "W3C";
    Matcher matcher = pattern.matcher(candidate);
    String tmp = matcher.replaceAll("$33");
    System.out.println("REPLACEMENT: " + tmp);
    System.out.println("ORIGINAL: " + candidate);
  }
}
