java根据开始时间结束时间计算中间间隔日期的实例代码

java根据开始时间结束时间计算中间间隔日期的实例代码

具体代码如下所述：

import java.text.ParseException;

import java.text.SimpleDateFormat;

import java.util.ArrayList;

import java.util.Calendar;

import java.util.Date;

import java.util.List;

public class Test {

public static List findDates(String stime, String etime)

throws ParseException {

List allDate = new ArrayList();

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

Date dBegin = sdf.parse(stime);

Date dEnd = sdf.parse(etime);

allDate.add(sdf.format(dBegin));

Calendar calBegin = Calendar.getInstance();

// 使用给定的 Date 设置此 Calendar 的时间

calBegin.setTime(dBegin);

Calendar calEnd = Calendar.getInstance();

// 使用给定的 Date 设置此 Calendar 的时间

calEnd.setTime(dEnd);

// 测试此日期是否在指定日期之后

while (dEnd.after(calBegin.getTime())) {

// 根据日历的规则，为给定的日历字段添加或减去指定的时间量

calBegin.add(Calendar.DAY_OF_MONTH, 1);

allDate.add(sdf.format(calBegin.getTime()));

}

return allDate;

}

public static void main(String[] args) {

//测试数据

String stime = "2019-05-01";

String etime = "2019-05-05";

//集合中包含2019-05-01/2019-05-05，不需要可去除

List list = new ArrayList<>();

try {

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

long s = Long.valueOf(sdf.parse(stime).getTime());

long e = Long.valueOf(sdf.parse(etime).getTime());

//只有结束时间大于开始时间时才进行查询

if(s

list = findDates(stime, etime);

}

} catch (ParseException e) {

e.printStackTrace();

}

for(String time : list) {

System.out.println(time);

}

System.out.println("间隔天数：" + list.size());

}

}

ps：下面看下java根据开始时间和结束时间，计算中间天数，并打印

import java.text.SimpleDateFormat;

long diff = (endTime.getTime() - beginTime.getTime()) / (86400 * 1000);

System.out.println("diff = " + diff);

Date sb = null;

Date se = null;

if(diff == 0){

sb = beginTime;

se = endTime;

String ss = String.format("%d> Sb=%s, Se=%s", 1, Coder.DateTimeToStr(sb), Coder.DateTimeToStr(se));

System.out.println(ss);

}else {

int i = 0;

while (i <= diff) {

if (i == 0) {

}

}

}

0> Sb=2015-04-23 12:32:44, Se=2015-04-23 23:59:59
