如何获得年月日时分秒

package com.gaofeng.controller;

import java.time.LocalDateTime;
import java.util.Calendar;

public class Test {
public static void main(String[] args) {
//方法一：
Calendar calendar=Calendar.getInstance();
System.out.println(calendar.get(Calendar.YEAR));
System.out.println(calendar.get(Calendar.MONTH));
System.out.println(calendar.get(Calendar.DATE));
System.out.println(calendar.get(Calendar.HOUR_OF_DAY));
System.out.println(calendar.get(Calendar.MINUTE));
System.out.println(calendar.get(Calendar.MINUTE));

//方法二：
    LocalDateTime localDateTime=LocalDateTime.now();
    System.out.println(localDateTime.getYear());
    System.out.println(localDateTime.getMonth());
    System.out.println(localDateTime.getHour());
    System.out.println(localDateTime.getMinute());
    System.out.println(localDateTime.getSecond());

}

}
