I get datetime data from soap web service to get string:2020-05-03T00:00:00.
Is there a way to split the string into dd / mm / yyyy, and if it is null then omitted?
I am using a substring(0,10) , but it doesn't work very well.
You can do it this way.
Parse the input string.
LocalDateTime dateTime = LocalDateTime.parse("2020-05-03T00:00:00");
Generate text representing the value of that LocalDateTime object.
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
String dateTimeString = dateTime.format(formatter);
System.out.println(dateTimeString);
03/05/2020
For early Android before 26, see the ThreeTenABP & ThreeTen-Backport projects, a back-port of most of the java.time functionality.
try with this
try {
SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = null;
date = inputFormat.parse("2020-05-03T00:00:00");
String formattedDate = outputFormat.format(date);
System.out.println("coverted: "+formattedDate);
} catch (ParseException e) {
e.printStackTrace();
}
Output: 03-05-2020
You can use java Calendar class to get Date, Month and Year as shown in below
String s = "2020-05-03T00:00:00";
Calendar calendar = new GregorianCalendar();
DateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date dateObj = null;
try {
dateObj = format.parse(s);
calendar.setTime(dateObj);
int date = calendar.get(Calendar.DATE);
int month = calendar.get(Calendar.MONTH) + 1;// As start from 0
int year = calendar.get(Calendar.YEAR);
System.out.println("Formatted Date -> "+ date + "/" + month + "/" +year);
} catch (ParseException e) {
e.printStackTrace();
}
You can do many more thing after converting it to Calendar class object, like hour, minutes, day of week etc

Datetime parsing error
(2 answers)
Closed 5 years ago.
I am struggling with a date string, I need to parse into the java ‘Date’ object.
Here is what I have got so far:
try {
String value = "2017-11-23T14:00:49.184000000Z";
String pattern = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSSS'Z'";
SimpleDateFormat parser = new SimpleDateFormat(pattern);
Date date = parser.parse(value);
} catch (ParseException e) {e.printStackTrace();}
It currently throws a ParseException “Unparseable date” and I can’t get it to work.
Any help is highly appreciated!
Thanks
Use Instant from java.time package (java 8) instead, it should look like below
String value = "2017-11-23T14:00:49.184000000Z";
Instant instant = Instant.parse(value);
Date date = Date.from(instant);
System.out.println(date);
you can use timeZone as well like this as another solution.
TimeZone tz = TimeZone.getTimeZone("Asia/Calcutta");
Calendar cal = Calendar.getInstance(tz);
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSSSSSSS'Z'");
sdf.setCalendar(cal);
cal.setTime(sdf.parse("2017-11-23T14:58:00.184000000Z"));
Date date = cal.getTime();
System.out.println(date);

Getting wrong month when using SimpleDateFormat.parse
(3 answers)
Closed 5 years ago.
I am trying to convert string of format yyyy-mm-dd to dd-MMM-yy. I am getting correct year and days but for month it is showing only jan irrespective of my input. How to fix it?
String input = "2013-09-14";
SimpleDateFormat format1 = new SimpleDateFormat("yyyy-mm-dd");
SimpleDateFormat format2 = new SimpleDateFormat("dd-MMM-yy");
Date date = null;
try {
date = format1.parse(input);
String temp = format2.format(date);
System.out.println(temp);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Output:
14-Jan-13
But I should get:
14-Oct-13
mm is for minute
you need MM or MMM for month.
See SimpleDateFormat for reference.
mm is for minutes. MM is for months.
SimpleDateFormat format1 = new SimpleDateFormat("yyyy-MM-dd");
I would suggest latest API LocalDate which not requires try/catch and which is easier to use :
String input = "2013-09-14";
LocalDate inputDate = LocalDate.parse(input, DateTimeFormatter.ISO_DATE);
String format = inputDate.format(DateTimeFormatter.ofPattern("dd-MMM-yy"));
System.out.println(format);
DateTimeFormatter.ISO_DATE is shortcut for DateTimeFormatter.ofPattern("yyyy-MM-dd");
LocalDate inputDate = LocalDate.parse(input); would also work because ISO_DATE the default format
DateTimeFormatter doc (patterns)
The pattern is case sensitive:
MM is month, mm is Minute:
SimpleDateFormat format1 = new SimpleDateFormat("yyyy-MM-dd");
For more Information read The javadoc of SimpleDateFormat
personally i used a pattern to do this,
LocalTime w = LocalTime.MIDNIGHT.plus(d);
s = DateTimeFormatter.ofPattern("HH:mm:ss").format(w);
and i advise you to use java 8 date type instead

android java parse date from string

Closed 5 years ago.
I have a date string in this format '20161201'.
How to make this a datetime string to be july 2016?
I want to show 6 months before that datetime string.
Is it possible?
Also how do I convert just '20161201' to Dec 2016?
you change the format using the following code,
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMdd", Locale.getDefault());
SimpleDateFormat expectedSDF = new SimpleDateFormat("MMMM yyyy", Locale.getDefault());
Date date = simpleDateFormat.parse(dateString);
String newFormatString = expectedSDF.format(date);
And for the countdown, use CountDownTimer
https://developer.android.com/reference/android/os/CountDownTimer.html
For convert '20161201' to 'Dec 2016':
//Convert string to date
String dateString = "20161201";
SimpleDateFormat parseDateFormat = new SimpleDateFormat("yyyyMMdd");
Date convertedDate = new Date();
try {
convertedDate = parseDateFormat.parse(dateString);
} catch (ParseException e) {
e.printStackTrace();
}
//Convert date to string
SimpleDateFormat outputDateFormat = new SimpleDateFormat("MMM yyyy");
String result = outputDateFormat.format(convertedDate);
//Print the result
System.out.println(result);
In '6 months' to millisecond is 15778476000. You can get the date after 6 months in millisecond by using
long resultdate = convertedDate.getTime() - 15778476000L;
and then
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(resultdate);
String result = outputDateFormat.format(calendar.getTime());
to get the result
https://developer.android.com/reference/java/text/SimpleDateFormat.html
https://developer.android.com/reference/java/util/Date.html
https://developer.android.com/reference/java/util/Calendar.html#setTimeInMillis(long)
how to make this datetime string to be july 2016
I want to show 6 months before that datetime string
July is 5 months...
Here's the 6 month answer
java.util.Calendar c = java.util.Calendar.getInstance();
c.setTime(new SimpleDateFormat("yyyyMMdd").parse("20161201"));
c.set(Calendar.MONTH, c.get(Calendar.MONTH)-6);
String output = new SimpleDateFormat("MMMM yyyy").format(c.getTime()));
// June 2016

Calculating the difference between two Java date instances
(45 answers)
Closed 7 years ago.
I need to get difference between two dates using Java. I need my result to be in months and year of month.
Example:
Startdate = 2015-04-03 enddate = 2015-05-03 Result should be APR-MAY 2015
Startdate = 2015-12-03 enddate = 2015-01-03 Result should be DEC-2015,JAn-2016
i need to set that value into textview how can i set this plz help me .
String startdate = "2015-11-30";
String enddate = "2016-1-30";
DateFormat formater = new SimpleDateFormat("yyyy-MM-dd");
DateFormat outputFormater = new SimpleDateFormat("MMM-yyyy");
Calendar beginCalendar = Calendar.getInstance();
Calendar finishCalendar = Calendar.getInstance();
try {
beginCalendar.setTime(formater.parse(startdate));
finishCalendar.setTime(formater.parse(enddate));
if (beginCalendar.get(Calendar.MONTH) != finishCalendar.get(Calendar.MONTH)){
beginCalendar.set(Calendar.DAY_OF_MONTH, 1);
finishCalendar.set(Calendar.DAY_OF_MONTH, 2);
}
do {
// add one month to date per loop
String month_year = outputFormater.format(beginCalendar.getTime());
Log.d("Date_Range", month_year);
beginCalendar.add(Calendar.MONTH, 1);
} while (beginCalendar.before(finishCalendar));
} catch (ParseException e) {
e.printStackTrace();
}
So by this you will get month and year between start date and end date in MMM-yyyy format. You can handle the result in the way you want by splitting month_year string # "-" separator.
You can use SimpleDateFormat.
EDIT: Try this
SimpleDateFormat formatter = new SimpleDateFormat("yyyy");
Check if your dates are in the same year by getting the year of the calendar.
int year1=Integer.pareInt(formatter.format(calendar1.getTime()));
int year2=Integer.pareInt(formatter.format(calendar2.getTime()));
year=year1-year2;
and then print result based on the year
formatter=new SimpleDateFormat("MMM");
if(year==0)
System.out.println(formatter.format(calendar1)+"-"+formatter.format(calendar2)+" "+ year);
else
System.out.println(formatter.format(calendar1)+"-"+year1+","+formatter.format(calendar2)+"-"+year2);

Change date format in a Java string

I have a object that giving date and time in this format "2014-06-11 16:32:36.828".
I want to remove millisec .828.
In my db that object is in time stamp format but whenever i am showing i am converting it to tostring().
so how to remove millisec please help me
The following code convert "2014-06-11 16:32:36.828" into "2014-06-11 16:32:36"
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").parse("2014-06-11 16:32:36.828"));
Explanation:
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").parse("2014-06-11 16:32:36.828") parse the input string into
Wed Jun 11 16:32:36 IST 2014
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) format the input date into specified structure.
I would use DateUtils.truncate(date, Calendar.SECOND)
Date d = SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(yourString);
Calendar c = Calendar.getInstance();
c.setTime(d);
c.set(Calendar.MILLISECOND, 0);
return c.getTime();
I remember there is a way to directly read Date off your timestamp field but I don't do that in my everyday coding. So I'd left for others to post so. Nevertheless, you can use the same above code to translate your date from that timestamp into a date without MILLISECOND.
If you receive it as a Timestamp, you should use the appropriate formatter when converting it to a string:
String s = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(timestamp);
Note: this will use the default time zone of the local computer.
Extract epoch millis from the original Date object and do integer division by 1000 followed by multiplication by 1000. Create Date object with the time zone of the original object and the millis calculated the above suggested way.
You can get the system time as follows without milliseconds
import java.text.SimpleDateFormat;
import java.util.Calendar;
And the code
Calendar currentDate = Calendar.getInstance();
SimpleDateFormat formatter= new SimpleDateFormat("dd-MM-YYYY-hh:mm:ss");
String dateNow = formatter.format(currentDate.getTime());
System.out.println(dateNow);
if you want to mantain the format try something like that:
public static String getFechaTimestampToString (Timestamp timestamp) {
String date = "";
Calendar cal = Calendar.getInstance();
cal.setTime(new Date(timestamp.getTime()));
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH)+1;
int day = cal.get(Calendar.DAY_OF_MONTH);
String monthstr = "";
String daystr = "";
if(month<10)
monthstr = "0"+month;
else
monthstr = ""+month;
if(day<10)
daystr = "0"+day;
else
daystr = ""+day;
date = year + "-" + monthstr + "-" + daystr ;
return date;
}
To reverse data to database:
public static Timestamp getFechaStringToTimestamp (String strDate) {
Timestamp timestamp = null;
strDate = strDate + " 00:00:00";
timestamp = Timestamp.valueOf(strDate);
return timestamp;
}
