下面给出一个示例,演示了如何使用DateUtils类来判断一个日期是否是今天: importjava.util.Date;publicclassMain{publicstaticvoidmain(String[]args){Datedate=newDate();if(DateUtils.isToday(date)){System.out.println("The date is today.");}else{System.out.println("The date is not today.");}}} 1...
另外,如果我们使用java.time.LocalDate来表示日期,获取当前日期的天数将更加简洁: importjava.time.LocalDate;publicclassMain{publicstaticvoidmain(String[]args){LocalDatecurrentDate=LocalDate.now();intday=currentDate.getDayOfMonth();System.out.println("Today's day is: "+day);}} 1. 2. 3. 4. 5...
另一种比较日期的方法是使用java.util.Date.getTime() (注意:应该使用long而不是int)，而不是上面...
//创建Date类,构造的时候填入当前的日期 Datedate=newDate(); System.out.println(date); //获得秒 finallongtime=date.getTime(); System.out.println(time); //将Date转换成更好识别的日期字符串 finalSimpleDateFormatformat=newSimpleDateFormat("yyyy年MM月dd日 HH:mm:ss E a"); finalStringformat1=...
import java.time.LocalDate;import java.time.temporal.ChronoUnit; public class Demo08 {public static void main(String[] args) {LocalDate today = LocalDate.now;System.out.println("今天的日期为:"+today);LocalDate nextWeek = today.plus(1, ChronoUnit.WEEKS);System.out.println("一周后的日期为...
The ISO-8601 calendar system is the modern civil calendar system used today in most of the world. It is equivalent to the proleptic Gregorian calendar system, in which today's rules for leap years are applied for all time. For most applications written today, the ISO-8601 rules are entirely...
