get current date in dd-mm-yyyy format - date

how to get current date in DD-MM-YYYY format in BlackBerry
i have already tried the following, but it gives me output of 1318502493
long currentTime = System.currentTimeMillis() / 1000;
System.out.println("Current time in :" + currentTime);


private String pattern = "dd-MM-yyyy";
String dateInString =new SimpleDateFormat(pattern).format(new Date());


DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
return formatter.format(new Date());


Check if you can use SimpleDateFormat. If you can, create an object of this class, and use it in order to format the return provided by System.currentTimeMillis(). Some code below:
import java.util.*;
import java.text.*;
public class DateTest {
public static String getCurrentTimeStamp() {
SimpleDateFormat formDate = new SimpleDateFormat("dd-MM-yyyy");
// String strDate = formDate.format(System.currentTimeMillis()); // option 1
String strDate = formDate.format(new Date()); // option 2
return strDate;
}
public static void main (String args[]) {
System.out.println(getCurrentTimeStamp());
}
}

How correctly create string with formatted date? [duplicate]

I want a list of dates between start date and end date.
The result should be a list of all dates including the start and end date.

java.time Package
If you are using Java 8, there is a much cleaner approach. The new java.time package in Java 8 incorporates the features of the Joda-Time API.
Your requirement can be solved using the below code:
String s = "2014-05-01";
String e = "2014-05-10";
LocalDate start = LocalDate.parse(s);
LocalDate end = LocalDate.parse(e);
List<LocalDate> totalDates = new ArrayList<>();
while (!start.isAfter(end)) {
totalDates.add(start);
start = start.plusDays(1);
}

Back in 2010, I suggested to use Joda-Time for that.
Note that Joda-Time is now in maintenance mode. Since 1.8 (2014), you should use java.time.
Add one day at a time until reaching the end date:
int days = Days.daysBetween(startDate, endDate).getDays();
List<LocalDate> dates = new ArrayList<LocalDate>(days); // Set initial capacity to `days`.
for (int i=0; i < days; i++) {
LocalDate d = startDate.withFieldAdded(DurationFieldType.days(), i);
dates.add(d);
}
It wouldn't be too hard to implement your own iterator to do this as well, that would be even nicer.

Get the number of days between dates, inclusive.
public static List<Date> getDaysBetweenDates(Date startdate, Date enddate)
{
List<Date> dates = new ArrayList<Date>();
Calendar calendar = new GregorianCalendar();
calendar.setTime(startdate);
while (calendar.getTime().before(enddate))
{
Date result = calendar.getTime();
dates.add(result);
calendar.add(Calendar.DATE, 1);
}
return dates;
}

Streams
Edit: Joda-Time is now deprecated, changed the answer to use Java 8 instead.
Here is the Java 8 way, using streams.
List<LocalDate> daysRange = Stream.iterate(startDate, date -> date.plusDays(1)).limit(numOfDays).collect(Collectors.toList());

please find the below code.
List<Date> dates = new ArrayList<Date>();
String str_date ="27/08/2010";
String end_date ="02/09/2010";
DateFormat formatter ;
formatter = new SimpleDateFormat("dd/MM/yyyy");
Date startDate = (Date)formatter.parse(str_date);
Date endDate = (Date)formatter.parse(end_date);
long interval = 24*1000 * 60 * 60; // 1 hour in millis
long endTime =endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
dates.add(new Date(curTime));
curTime += interval;
}
for(int i=0;i<dates.size();i++){
Date lDate =(Date)dates.get(i);
String ds = formatter.format(lDate);
System.out.println(" Date is ..." + ds);
}
output:
Date is ...27/08/2010
Date is ...28/08/2010
Date is ...29/08/2010
Date is ...30/08/2010
Date is ...31/08/2010
Date is ...01/09/2010
Date is ...02/09/2010

Recommending date streams
In Java 9, you can use following new method, LocalDate::datesUntil:
LocalDate start = LocalDate.of(2017, 2, 1);
LocalDate end = LocalDate.of(2017, 2, 28);
Stream<LocalDate> dates = start.datesUntil(end.plusDays(1));
List<LocalDate> list = dates.collect(Collectors.toList());
The new method datesUntil(...) works with an exclusive end date, hence the shown hack to add a day.
Once you have obtained a stream you can exploit all the features offered by java.util.stream- or java.util.function-packages. Working with streams has become so simple compared with earlier approaches based on customized for- or while-loops.
Or if you look for a stream-based solution which operates on inclusive dates by default but can also be configured otherwise then you might find the class DateInterval in my library Time4J interesting because it offers a lot of special features around date streams including a performant spliterator which is faster than in Java-9:
PlainDate start = PlainDate.of(2017, 2, 1);
PlainDate end = start.with(PlainDate.DAY_OF_MONTH.maximized());
Stream<PlainDate> stream = DateInterval.streamDaily(start, end);
Or even simpler in case of full months:
Stream<PlainDate> februaryDates = CalendarMonth.of(2017, 2).streamDaily();
List<LocalDate> list =
februaryDates.map(PlainDate::toTemporalAccessor).collect(Collectors.toList());

With java 8
public Stream<LocalDate> getDaysBetween(LocalDate startDate, LocalDate endDate) {
return IntStream.range(0, (int) DAYS.between(startDate, endDate)).mapToObj(startDate::plusDays);
}

Something like this should definitely work:
private List<Date> getListOfDaysBetweenTwoDates(Date startDate, Date endDate) {
List<Date> result = new ArrayList<Date>();
Calendar start = Calendar.getInstance();
start.setTime(startDate);
Calendar end = Calendar.getInstance();
end.setTime(endDate);
end.add(Calendar.DAY_OF_YEAR, 1); //Add 1 day to endDate to make sure endDate is included into the final list
while (start.before(end)) {
result.add(start.getTime());
start.add(Calendar.DAY_OF_YEAR, 1);
}
return result;
}

With Lamma it looks like this in Java:
for (Date d: Dates.from(2014, 6, 29).to(2014, 7, 1).build()) {
System.out.println(d);
}
and the output is:
Date(2014,6,29)
Date(2014,6,30)
Date(2014,7,1)

public static List<Date> getDaysBetweenDates(Date startDate, Date endDate){
ArrayList<Date> dates = new ArrayList<Date>();
Calendar cal1 = Calendar.getInstance();
cal1.setTime(startDate);
Calendar cal2 = Calendar.getInstance();
cal2.setTime(endDate);
while(cal1.before(cal2) || cal1.equals(cal2))
{
dates.add(cal1.getTime());
cal1.add(Calendar.DATE, 1);
}
return dates;
}

One solution would be to create a Calendar instance, and start a cycle, increasing it's Calendar.DATE field until it reaches the desired date. Also, on each step you should create a Date instance (with corresponding parameters), and put it to your list.
Some dirty code:
public List<Date> getDatesBetween(final Date date1, final Date date2) {
List<Date> dates = new ArrayList<Date>();
Calendar calendar = new GregorianCalendar() {{
set(Calendar.YEAR, date1.getYear());
set(Calendar.MONTH, date1.getMonth());
set(Calendar.DATE, date1.getDate());
}};
while (calendar.get(Calendar.YEAR) != date2.getYear() && calendar.get(Calendar.MONTH) != date2.getMonth() && calendar.get(Calendar.DATE) != date2.getDate()) {
calendar.add(Calendar.DATE, 1);
dates.add(new Date(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DATE)));
}
return dates;
}

You can also look at the Date.getTime() API. That gives a long to which you can add your increment. Then create a new Date.
List<Date> dates = new ArrayList<Date>();
long interval = 1000 * 60 * 60; // 1 hour in millis
long endtime = ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
dates.add(new Date(curTime));
curTime += interval;
}
and maybe apache commons has something like this in DateUtils, or perhaps they have a CalendarUtils too :)
EDIT
including the start and enddate may not be possible if your interval is not perfect :)

List<Date> dates = new ArrayList<Date>();
String str_date = "DD/MM/YYYY";
String end_date = "DD/MM/YYYY";
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
Date startDate = (Date)formatter.parse(str_date);
Date endDate = (Date)formatter.parse(end_date);
long interval = 1000 * 60 * 60; // 1 hour in milliseconds
long endTime = endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
dates.add(new Date(curTime));
curTime += interval;
}
for (int i = 0; i < dates.size(); i++){
Date lDate = (Date)dates.get(i);
String ds = formatter.format(lDate);
System.out.println("Date is ..." + ds);
//Write your code for storing dates to list
}

Like as #folone, but correct
private static List<Date> getDatesBetween(final Date date1, final Date date2) {
List<Date> dates = new ArrayList<>();
Calendar c1 = new GregorianCalendar();
c1.setTime(date1);
Calendar c2 = new GregorianCalendar();
c2.setTime(date2);
int a = c1.get(Calendar.DATE);
int b = c2.get(Calendar.DATE);
while ((c1.get(Calendar.YEAR) != c2.get(Calendar.YEAR)) || (c1.get(Calendar.MONTH) != c2.get(Calendar.MONTH)) || (c1.get(Calendar.DATE) != c2.get(Calendar.DATE))) {
c1.add(Calendar.DATE, 1);
dates.add(new Date(c1.getTimeInMillis()));
}
return dates;
}

With Joda-Time , maybe it's better:
LocalDate dateStart = new LocalDate("2012-01-15");
LocalDate dateEnd = new LocalDate("2012-05-23");
// day by day:
while(dateStart.isBefore(dateEnd)){
System.out.println(dateStart);
dateStart = dateStart.plusDays(1);
}
It's my solution.... very easy :)

This is simple solution for get a list of dates
import java.io.*;
import java.util.*;
import java.text.SimpleDateFormat;
public class DateList
{
public static SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
public static void main (String[] args) throws java.lang.Exception
{
Date dt = new Date();
System.out.println(dt);
List<Date> dates = getDates("2017-01-01",dateFormat.format(new Date()));
//IF you don't want to reverse then remove Collections.reverse(dates);
Collections.reverse(dates);
System.out.println(dates.size());
for(Date date:dates)
{
System.out.println(date);
}
}
public static List<Date> getDates(String fromDate, String toDate)
{
ArrayList<Date> dates = new ArrayList<Date>();
try {
Calendar fromCal = Calendar.getInstance();
fromCal.setTime(dateFormat .parse(fromDate));
Calendar toCal = Calendar.getInstance();
toCal.setTime(dateFormat .parse(toDate));
while(!fromCal.after(toCal))
{
dates.add(fromCal.getTime());
fromCal.add(Calendar.DATE, 1);
}
} catch (Exception e) {
System.out.println(e);
}
return dates;
}
}

As of Java 9, you can use the datesUntil method on LocalDate:
public List<LocalDate> getDatesBetween(
LocalDate startDate, LocalDate endDate) {
return startDate.datesUntil(endDate)
.collect(Collectors.toList());
}

The LocalDateRange class in the ThreeTen-Extra library represents a range of dates, and can be used for this purpose:
LocalDateRange.ofClosed(startDate, endDate).stream().toList();

A tail-recursive version:
public static void datesBetweenRecursive(Date startDate, Date endDate, List<Date> dates) {
if (startDate.before(endDate)) {
dates.add(startDate);
Calendar calendar = Calendar.getInstance();
calendar.setTime(startDate);
calendar.add(Calendar.DATE, 1);
datesBetweenRecursive(calendar.getTime(), endDate, dates);
}
}

Enhancing one of the above solutions. As adding 1 day to end date sometimes adds an extra day beyond the end date.
public static List getDaysBetweenDates(Date startdate, Date enddate)
{
List dates = new ArrayList();
Calendar startDay = new GregorianCalendar();
calendar.setTime(startdate);
Calendar endDay = new GregorianCalendar();
endDay.setTime(enddate);
endDay.add(Calendar.DAY_OF_YEAR, 1);
endDay.set(Calendar.HOUR_OF_DAY, 0);
endDay.set(Calendar.MINUTE, 0);
endDay.set(Calendar.SECOND, 0);
endDay.set(Calendar.MILLISECOND, 0);
while (calendar.getTime().before(endDay.getTime())) {
Date result = startDay.getTime();
dates.add(result);
startDay.add(Calendar.DATE, 1);
}
return dates;
}

Here is my method for getting dates between two dates, including / w.o. including business days. It also takes source and desired date format as parameter.
public static List<String> getAllDatesBetweenTwoDates(String stdate,String enddate,String givenformat,String resultformat,boolean onlybunessdays) throws ParseException{
DateFormat sdf;
DateFormat sdf1;
List<Date> dates = new ArrayList<Date>();
List<String> dateList = new ArrayList<String>();
SimpleDateFormat checkformat = new SimpleDateFormat(resultformat);
checkformat.applyPattern("EEE"); // to get Day of week
try{
sdf = new SimpleDateFormat(givenformat);
sdf1 = new SimpleDateFormat(resultformat);
stdate=sdf1.format(sdf.parse(stdate));
enddate=sdf1.format(sdf.parse(enddate));
Date startDate = (Date)sdf1.parse( stdate);
Date endDate = (Date)sdf1.parse( enddate);
long interval = 24*1000 * 60 * 60; // 1 hour in millis
long endTime =endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
dates.add(new Date(curTime));
curTime += interval;
}
for(int i=0;i<dates.size();i++){
Date lDate =(Date)dates.get(i);
String ds = sdf1.format(lDate);
if(onlybunessdays){
String day= checkformat.format(lDate);
if(!day.equalsIgnoreCase("Sat") && !day.equalsIgnoreCase("Sun")){
dateList.add(ds);
}
}else{
dateList.add(ds);
}
//System.out.println(" Date is ..." + ds);
}
}catch(ParseException e){
e.printStackTrace();
throw e;
}finally{
sdf=null;
sdf1=null;
}
return dateList;
}
And the method call would be like :
public static void main(String aregs[]) throws Exception {
System.out.println(getAllDatesBetweenTwoDates("2015/09/27","2015/10/05","yyyy/MM/dd","dd-MM-yyyy",false));
}
You can find the demo code : Click Here

List<LocalDate> totalDates = new ArrayList<>();
popularDatas(startDate, endDate, totalDates);
System.out.println(totalDates);
private void popularDatas(LocalDate startDate, LocalDate endDate, List<LocalDate> datas) {
if (!startDate.plusDays(1).isAfter(endDate)) {
popularDatas(startDate.plusDays(1), endDate, datas);
}
datas.add(startDate);
}
Recursive solution

This will add all dates between two dates and It will add current dates and then new dates will be added based on loop condition.
private void onDateSet(){
Calendar endDate = Calendar.getInstance(),startDate = Calendar.getInstance();
startDate.set(currentYear,currentMonthOfYear,currentDayOfMonth);
endDate.set(inputYear,inputMonthOfYear,inputDayOfMonth);
datesToAdd(startDate,endDate);
}
//call for get dates list
private List<Date> datesToAdd(Calendar startDate,Calendar endDate){
List<Dates> datesLists = new List<>();
while (startDate.get(Calendar.YEAR) != endDate.get(Calendar.YEAR) ||
startDate.get(Calendar.MONTH) != endDate.get(Calendar.MONTH) ||
startDate.get(Calendar.DAY_OF_MONTH) != endDate.get(Calendar.DAY_OF_MONTH)) {
datesList.add(new Date(startDate.get(Calendar.YEAR), startDate.get(Calendar.MONTH), startDate.get(Calendar.DATE));
startDate.add(Calendar.DATE, 1);//increas dates
}
return datesList;
}

Need to convert my server timestamp string to another timezone in 'yyyy-MM-dd' format in java

I have an input string like :
billDate="2016-03-16T10:48:59+05:30" (please see the T in between).
Now I want to convert this to another timestamp (America/New_York).
My final result should be like 16 march 2016 or 15th march 2016 depending upon the hour value.
I saw many examples but got no hint how I can convert the above long datetime string to another string for America/New_York.
Can somebody help me on this?
I tried below code but it always gives 16 march for any hour value.
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
public class Test {
public static void main(String[] args) {
String output = formatDate("2016-03-1611T:27:58+05:30");
System.out.println(output);
}
public static String formatDate(String inputDate) {
try {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
sdf.setTimeZone(TimeZone.getTimeZone("America/New_York"));
Date parsedDate = sdf.parse(inputDate);
return sdf.format(parsedDate);
}
catch (ParseException e) {
// handle exception
}
return null;
}
}

After trying I finally got the code to solve the issue:
The below code works fine:
import java.util.Date;
import java.util.TimeZone;
import java.text.SimpleDateFormat;
public class Test {
public static final SimpleDateFormat fDateTime = new SimpleDateFormat(
"yyyy-MM-dd'T'HH:mm:ss");
public static void main(String[] args) {
String output = getFormattedDate("2016-03-1611T23:27:58+05:30");
System.out.println(output);
}
public static String getFormattedDate(String inputDate) {
try {
Date dateAfterParsing = fDateTime.parse(inputDate);
fDateTime.setTimeZone(TimeZone.getTimeZone("timeZone"));
return fDateTime.format(dateAfterParsing);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}

Date time library for gwt

I am working on a gwt application which involves advanced manipulations with date times: convert from one timezone to another, etc. Gwt has some low level stuff for working with dates but they are too low level for me. Are there any options similar to joda time or threeten for gwt?

You could look at the following options.
http://code.google.com/p/gwt-time/
http://code.google.com/p/goda-time/
http://github.com/mping/gwt-joda-time

This is my DateTimeUtil class
public class DateTimeUtil {
public static String getYear(Date date) {
return DateTimeFormat.getFormat("yyyy").format(date);
}
public static String getMonth(Date date) {
return DateTimeFormat.getFormat("MM").format(date);
}
public static String getDay(Date date) {
return DateTimeFormat.getFormat("dd").format(date);
}
public static String getHour(Date date) {
return DateTimeFormat.getFormat("HH").format(date);
}
public static String getMinute(Date date) {
return DateTimeFormat.getFormat("mm").format(date);
}
public static String getSecond(Date date) {
return DateTimeFormat.getFormat("ss").format(date);
}
// The String year must to have yyyy format
public static Date getDate(String years, String months, String days, String hours, String minutes, String seconds) {
DateTimeFormat dtf = DateTimeFormat.getFormat("yyyy-MM-dd HH:mm:ss");
Date date = dtf.parse(years + "-" + months + "-" + days + " " + hours + ":" + minutes + ":" + seconds);
GWT.log("date parsed " + date);
return date;
}
}

"Pretty time" for GWT

There is a "Pretty time" library for Java based on this post:
How to calculate "time ago" in Java?
Is there anything like this for GWT?

GWT relative time

I will not recommend you to include some 3-rd parties for this task - there is more simple way.
Just count number of seconds, minutes, hours, ...e.t.c. and then format the result text - use Plural Forms - built in GWT i18n tool for formatting such text as
"one second", "two seconds", e.t.c. So all messages will be localized and stored into i18n resources, no any hardcode.

I coded this for an Android java project. I created a class with 2 methods:
