System.out.println("两个日期相差 "+diffInDays+" 天"); 1. 完整代码示例 将上述步骤整合到一起,我们可以得到以下完整的代码示例: importjava.util.Date;importjava.util.Calendar;publicclassDateDifferenceCalculator{publicstaticvoidmain(String[]args){Datedate1=newDate();// 当前时间Calendarcalendar=Calendar...
ChronoUnit; public class DateDifference { public static void main(String[] args) { // 起始日期 LocalDate startDate = LocalDate.parse("2022-01-01"); // 结束日期 LocalDate endDate = LocalDate.parse("2022-01-10"); // 计算天数差异 long daysDiff = ChronoUnit.DAYS.between(startDate, endDa...
private static long daysBetween(Date one, Date two) { long difference = (one.getTime()-two.getTime())/86400000; return Math.abs(difference); } 这种方式由于计算简单,为广大开发人员所采用。 注意:由于转换成毫秒数计算,如果要获得较为准确的结果,应将日期规整,即将日期的时分秒设置为0:00点整点,避...
Date date2 = new Date(); // 第二个日期 // 计算日期之间的毫秒差值 long differenceInMilliseconds = date2.getTime() - date1.getTime(); // 转换毫秒差值为天数 long differenceInDays = TimeUnit.MILLISECONDS.toDays(differenceInMilliseconds); ...
Date startDate = new Date(); Date endDate = DateUtils.addDays(startDate, 7); long daysDiff = DateUtils.getFragmentInDays(endDate, startDate); System.out.println("Days difference between two dates: " + daysDiff); 复制代码 计算一个日期加上指定天数后的日期: Date currentDate = new Date...
可以使用Java中的Calendar类来计算两个日期之间的差值。下面是一个示例代码,演示如何计算两个日期之间的天数差值: import java.util.Calendar; public class DateDifferenceCalculator { public static void main(String[] args) { Calendar cal1 = Calendar.getInstance(); Calendar cal2 = Calendar.getInstance(); ...
Note that the start date is included, but the end date is excluded. The result of this method can be a negative period if the end is before the start. As stated above, Periodclass represents the time difference in the format of “x years, y months and z days”. So, when we call ...
2.1. Using java.util.Date to Find the Difference in Days Let’s start by using the core Java APIs to do the calculation and determine the number of days between the two dates: @Test public void givenTwoDatesBeforeJava8_whenDifferentiating_thenWeGetSix() throws ParseException { SimpleDateFo...
