JAVA时间日期处理类实例

本文实例讲述了JAVA时间日期处理类，主要用来遍历两个日期之间的每一天。分享给大家供大家参考。具体如下：

import java.text.DecimalFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class AccountDate {
 private static transient int gregorianCutoverYear = 1582;
 
 private static final int[] DAYS_P_MONTH_LY= {31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
 
 private static final int[] DAYS_P_MONTH_CY= {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
 
 private static final int Y = 0, M = 1, D = 2;
 
 public static int[] splitYMD(String date){
  date = date.replace("-", "");
  int[] ymd = {0, 0, 0};
  ymd[Y] = Integer.parseInt(date.substring(0, 4));
  ymd[M] = Integer.parseInt(date.substring(4, 6));
  ymd[D] = Integer.parseInt(date.substring(6, 8));
  return ymd;
 }
 
 public static boolean isLeapYear(int year) {
  return year >= gregorianCutoverYear ?
   ((year%4 == 0) && ((year%100 != 0) || (year%400 == 0))) : (year%4 == 0); 
 }
 
 private static int[] addoneDay(int year, int month, int day){
  if(isLeapYear( year )){
   day++;
   if( day > DAYS_P_MONTH_LY[month -1 ] ){
    month++;
    if(month > 12){
     year++;
     month = 1;
    }
    day = 1;
   }
  }else{
   day++;
   if( day > DAYS_P_MONTH_CY[month -1 ] ){
    month++;
    if(month > 12){
     year++;
     month = 1;
    }
    day = 1;
   }
  }
  int[] ymd = {year, month, day};
  return ymd;
 }
 
 public static String formatMonthDay(int decimal){
  DecimalFormat df = new DecimalFormat("00");
  return df.format( decimal );
 }
 
 public static String formatYear(int decimal){
  DecimalFormat df = new DecimalFormat("0000");
  return df.format( decimal );
 }
 
 public static long countDay(String begin,String end){
   SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
   Date beginDate , endDate;
   long day = 0;
   try {
   beginDate= format.parse(begin);
   endDate= format.parse(end);
   day=(endDate.getTime()-beginDate.getTime())/(24*60*60*1000); 
  } catch (ParseException e) {
   e.printStackTrace();
  }    
   return day;
 }
 
 public static List getEveryday(String beginDate , String endDate){
  long days = countDay(beginDate, endDate);
  int[] ymd = splitYMD( beginDate );
  List everyDays = new ArrayList();
  everyDays.add(beginDate);
  for(int i = 0; i < days; i++){
   ymd = addoneDay(ymd[Y], ymd[M], ymd[D]);
   everyDays.add(formatYear(ymd[Y])+"-"+formatMonthDay(ymd[M])+"-"+formatMonthDay(ymd[D]));
  }
  return everyDays;
 }
 public static void main(String[] args) {
  List list = AccountDate.getEveryday("2008-08-29", "2008-09-02");
  for (String result : list) {
   System.out.println(result);
  }
 }
}

希望本文所述对大家的java程序设计有所帮助。
