在Java中计算两个日期间的天数,大致有2种方法:一是使用原生JDK进行计算,在JDK8中提供了更为直接和完善的方法;二是使用第三方库。 1、使用原生的JDK privatestaticlong daysBetween(Date one, Date two) { long difference = (one.getTime()-two.getTime())/86400000; ...
在Java中,可以使用compareTo()方法来比较两个日期的大小。 import java.time.LocalDate; public class CompareDates { public static void main(String[] args) { LocalDate date1 = LocalDate.of(2021, 1, 1); LocalDate date2 = LocalDate.of(2022, 1, 1); int result = date1.compareTo(date2);...
