LocalDateTime取年月日

以下是使用LocalDateTime获取年月日的方法：

import java.time.LocalDateTime;

public class Main {
    public static void main(String[] args) {
        LocalDateTime localDateTime = LocalDateTime.now();

        int year = localDateTime.getYear();
        int month = localDateTime.getMonthValue();
        int day = localDateTime.getDayOfMonth();

        System.out.println("Year: " + year);
        System.out.println("Month: " + month);
        System.out.println("Day: " + day);
    }
}

输出结果：

Year: 2021
Month: 10
Day: 20
