date1:2009-12-31date2:2019-01-31Date1 时间在 Date2 之前 2. Date.before(),Date.after()和Date.equals() 一种语义上比较友好的方法来比较两个java.util.Date 代码语言:javascript 代码运行次数:0 运行 AI代码解释 @TestvoidtestDateCompare2()throws Par
date类型日期的before方法和after方法只能比较大于小于,不能比较大于等于,小于等于,结合equals就可以实现了,如下: 代码语言:javascript 代码运行次数: ifsd1nowsd1&&)||sd2.equals(now))} sd1和sd2是要拿来比较的date类型,now是现在时间 意思就是:sd1<=now<=sd2...

这个方法会比较两个Date对象的毫秒数的差值。 Datedate1=newDate();Datedate2=newDate();intresult=date1.compareTo(date2);if(result==0){System.out.println("Date1 is equal to Date2");}elseif(result<0){System.out.println("Date1 is before Date2");}else{System.out.println("Date1 is afte...
以下程序说明了Java中ChronoLocalDate的 isEqual() 方法。程序1 :// Program to illustrate the isEqual() method import java.util.*; import java.time.*; import java.time.chrono.*; public class GfG { public static void main(String[] args) { // Parses the first date ChronoLocalDate dt1 = ...
compareTo()方法的返回值,date1小于date2返回-1,date1大于date2返回1,相等返回0 方法二:通过Date自带的before()或者after()方法比较 String beginTime = "2018-07-28 14:42:32"; String endTime = "2018-07-29 12:26:32"; SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")...
