如何获得两个Java LocalDate之间的天，月和年？
设置两个Java日期：
LocalDate date1 = LocalDate.of(2019, 3, 25); LocalDate date2 = LocalDate.of(2019, 4, 29);
现在，使用Period类between()方法获取两个日期之间的差：
Period p = Period.between(date1, date2);
现在，获取年，月和日：
p.getYears() p.getMonths() p.getDays()
示例
import java.time.LocalDate;
import java.time.Period;
public class Demo {
public static void main(String[] args) {
LocalDate date1 = LocalDate.of(2019, 3, 25);
LocalDate date2 = LocalDate.of(2019, 4, 29);
System.out.println("Date 1 = "+date1);
System.out.println("Date 2 = "+date2);
Period p = Period.between(date1, date2);
System.out.println("Period = "+p);
System.out.println("Years (Difference) = "+p.getYears());
System.out.println("Month (Difference) = "+p.getMonths());
System.out.println("Days (Difference) = "+p.getDays());
}
}输出结果
Date 1 = 2019-03-25 Date 2 = 2019-04-29 Period = P1M4D Years (Difference) = 0 Month (Difference) = 1 Days (Difference) = 4
