Java正则表达式将日期格式提取到月份和年份

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

public class DateExtractor {
    public static void main(String[] args) {
        String date = "Today is 2022-01-01";
        String pattern = "(\\d{4})-(\\d{2})-\\d{2}";

        Pattern regex = Pattern.compile(pattern);
        Matcher matcher = regex.matcher(date);

        if (matcher.find()) {
            String year = matcher.group(1);
            String month = matcher.group(2);
            System.out.println("Year: " + year);
            System.out.println("Month: " + month);
        }
    }
}

Year: 2022
Month: 01
