在Clojure或Java中使用正则表达式时，如何使用命名捕获组？

(let [regex #"^(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})$"
      input "2022-01-01"
      result (re-matches regex input)]
  (if result
    (println "Year:" (:year result) "Month:" (:month result) "Day:" (:day result))
    (println "No match found.")))

import java.util.regex.*;

public class RegexExample {
    public static void main(String[] args) {
        String regex = "^(?<year>\\d{4})-(?<month>\\d{2})-(?<day>\\d{2})$";
        String input = "2022-01-01";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(input);
        
        if (matcher.matches()) {
            System.out.println("Year: " + matcher.group("year"));
            System.out.println("Month: " + matcher.group("month"));
            System.out.println("Day: " + matcher.group("day"));
        } else {
            System.out.println("No match found.");
        }
    }
}
