How do I use reluctant quantifier regex in Java?

The reluctant quantifiers start the matcher at the beginning of the input string, then reluctantly eat one character at a time looking for a match. The last thing they try is the entire input string.

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ReluctantQuantifierDemo {
    public static void main(String[] args) {
        String[] regexs = {
                "x??",
                "x*?",
                "x+?",
                "x{2}?",
                "x{2,}?",
                "x{2,5}?"
        };
        String text = "xxxxxxx";

        for (String r : regexs) {
            Pattern pattern = Pattern.compile(r);
            Matcher matcher = pattern.matcher(text);

            //
            // Find every match and print it
            //
            System.out.println("------------------------------");
            System.out.format("regex:  %s %n", r);
            while (matcher.find()) {
                System.out.format("Text \"%s\" found at %d to %d.%n",
                        matcher.group(), matcher.start(),
                        matcher.end());
            }
        }
    }
}
