A greedy qualifier

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MainClass {
  public static void main(String args[]) {
    String regex = "(\\w+)(\\d\\d)(\\w+)";
    Pattern pattern = Pattern.rupile(regex);
    String candidate = "AAA99SuperJava";
    Matcher matcher = pattern.matcher(candidate);
    matcher.find();
    System.out.println(matcher.group(1));
    System.out.println(matcher.group(2));
    System.out.println(matcher.group(3));
  }
}

A Reluctant qualifier

import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MainClass {
  public static void main(String args[]) {
    String regex = "(\\d+?)";
    Pattern pattern = Pattern.rupile(regex);
    String candidate = "1234";
    Matcher matcher = pattern.matcher(candidate);
    System.out.println(matcher.group());
  }
