java获取日期之间天数的方法
本文实例讲述了java获取日期之间天数的方法。分享给大家供大家参考。具体实现方法如下：
privateintdaysBetween(Datenow,DatereturnDate){
CalendarcNow=Calendar.getInstance();
CalendarcReturnDate=Calendar.getInstance();
cNow.setTime(now);
cReturnDate.setTime(returnDate);
setTimeToMidnight(cNow);
setTimeToMidnight(cReturnDate);
longtodayMs=cNow.getTimeInMillis();
longreturnMs=cReturnDate.getTimeInMillis();
longintervalMs=todayMs-returnMs;
returnmillisecondsToDays(intervalMs);
}
privateintmillisecondsToDays(longintervalMs){
return(int)(intervalMs/(1000*86400));
}
privatevoidsetTimeToMidnight(Calendarcalendar){
calendar.set(Calendar.HOUR_OF_DAY,0);
calendar.set(Calendar.MINUTE,0);
calendar.set(Calendar.SECOND,0);
}
希望本文所述对大家的java程序设计有所帮助。
