将字符串转换为日历.什么是最简单的方法？

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;

public class StringToCalendar {
    public static void main(String[] args) {
        String dateString = "2022-01-01";
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        try {
            Calendar calendar = Calendar.getInstance();
            calendar.setTime(sdf.parse(dateString));
            System.out.println("日历对象：" + calendar);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}
