Here is the code to parse date and it throws parse exception. Can anyone help to resolve this? I do not want to use any other third party API.
DateFormat df = new SimpleDateFormat("dd-MM-yyyy HH:mm:ssZ");
Date newDate;
try {
newDate = df.parse("28-04-2016 23:59:59 US/Eastern");
df.setTimeZone(TimeZone.getTimeZone("UTC"));
String strdate = df.format(newDate);
System.out.println("The date and time in :: UTC is ::" + strdate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
the Timezone handlling in simple java APIs are not that straightforward and thats why Java included JODA time with Java 8. In order to acheive your problem you can do something like below:
String sourceDateTimeTz = "28-04-2016 23:59:59 US/Eastern";
String sourceDateTime = sourceDateTimeTz.substring(0, 19);
TimeZone sourceTz = TimeZone.getTimeZone(sourceDateTimeTz.substring(20));
DateFormat df = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
Date sourceDate;
try {
sourceDate = df.parse(sourceDateTime);
Calendar sourceCalendar = Calendar.getInstance();
sourceCalendar.setTime(sourceDate);
sourceCalendar.setTimeZone(sourceTz);
Calendar targetCalendar = Calendar.getInstance();
for (int field : new int[] { Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, Calendar.HOUR,
Calendar.MINUTE, Calendar.SECOND, Calendar.MILLISECOND }) {
targetCalendar.set(field, sourceCalendar.get(field));
}
targetCalendar.setTimeZone(TimeZone.getTimeZone("UTC"));
Date targetDate = targetCalendar.getTime();
System.out.println(df.format(targetDate));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

My string date --> 2016-10-02T00:00:00.000Z. I want to get only date from this string. I tried to parse through below coding but it throws me error! I have exactly the same format as mentioned in the string. Any answers?
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
try {
Date myDate = sdf.parse( dateofJoining.replaceAll( "([0-9\\-T]+:[0-9]{2}:[0-9.+]+):([0-9]{2})", "$1$2" ) );
System.out.println("Date only"+ myDate );
} catch (ParseException e) {
e.printStackTrace();
}
I also tired below code,
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
try {
Date date = format.parse(dtStart);
System.out.println(date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
The error which i get
java.text.ParseException: Unparseable date: "2016-10-02T00:00:00.000Z" (at offset 19)
05-12 00:18:36.613 4330-4330/com.vroom.riderb2b W/System.err: at java.text.DateFormat.parse
change the simple date format to use: yyyy-MM-dd'T'HH:mm:ss.SSSZ
in your code:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
try {
Date date = format.parse(dtStart.replaceAll("Z$", "+0000"));
System.out.println(date);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
If you want to get date/mm/yy from it:
use:
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yy");
// use UTC as timezone
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
Log.i("DATE", sdf.format(date)); //previous date object parsed
if you want output format: hour:minute AM/PM
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a", Locale.ENGLISH);
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.out.println(sdf.format(date));
EDIT
More easier option is to split the string in two parts like:
String dateString = "2016-10-02T00:00:00.000Z";
String[] separated = dateString.split("T");
separated[0]; // this will contain "2016-10-02"
separated[1]; // this will contain "00:00:00.000Z"
try with this :
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
Try
Calendar calendar = Calendar.getInstance();
TimeZone localTZ = calendar.getTimeZone();
String format1 = "yyyy-MM-dd"; //will return 2017-01-31
String format2 = "dd"; //will return DAY only like 31
SimpleDateFormat sdf = new SimpleDateFormat(format);
sdf.setTimeZone(localTZ );
String result = sdf.format(your_date);
For me it's worked like this:
textView_last_comm.setText(parseDateFormat(passDetailsModel.getLast_comm(), "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "dd/MM/yy HH:mm"));
public static String parseDateFormat(String dateToFormat, String inputFormat, String outputFormat) {
SimpleDateFormat inputFormat = new SimpleDateFormat(inputFormat);
SimpleDateFormat outputFormat = new SimpleDateFormat(outputFormat);
Date date = null;
String str = null;
try {
date = inputFormat.parse(dateToFormat);
str = outputFormat.format(date);
} catch (ParseException e) {
e.printStackTrace();
}
return str;
}
You can get date easily by using String.substring() method:
String string = "2016-10-02T00:00:00.000Z";
String date = string.substring(0, 10);
Log.d("SUCCESS", "DATE: " + date);
OUTPUT:
D/SUCCESS: DATE: 2016-10-02
I need to convert a UTC time string into my local time, the code works fine in my PC when I run it on Eclipse, however, I get incorrect results on Android. I am stuck, can someone help.
Below is the code I am using, an example input would be "2017-04-24 1:00 AM", this will yield a result of "11:00 AM" which is what I am expecting, however, it always return "10:00 AM" on Android.
public String convertUTCTime(String utcTime) {
Calendar cal = Calendar.getInstance();
TimeZone tz = cal.getTimeZone();
SimpleDateFormat sdf = new SimpleDateFormat("yyy-MM-dd HH:mm a");
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
try {
Date date = sdf.parse(utcTime);
sdf = new SimpleDateFormat("HH:mm a");
sdf.setTimeZone(tz);
String format = sdf.format(date);
return format;
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "Not applicable";
}
Look I prepared function:-
public static String getUTCDate(String timestamp, String DateFormat) {
SimpleDateFormat originalFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm aa", Locale.getDefault());
originalFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
SimpleDateFormat targetFormat = new SimpleDateFormat(DateFormat, Locale.getDefault());
targetFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
Date date = null;
String formattedDate = null;
try {
date = originalFormat.parse(timestamp);
formattedDate = targetFormat.format(date);
} catch (ParseException e) {
e.printStackTrace();
}
return formattedDate;
}
Get the value by calling -
Utils.getUTCDate("2017-04-24 01:00 AM", "HH:mm a")
I'm trying to convert a date (string) extracted from a csv file, convert it to sql timestamp and upload using prepared statement. What I have is:
String test = "8/10/2014 16:59";
DateFormat fromFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm");
fromFormat.setLenient(false);
DateFormat toFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss.SSSSSS");
toFormat.setLenient(false);
Date date2 = null;
try {
date2 = toFormat.parse(test);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//java.sql.Timestamp ts2 = java.sql.Timestamp.valueOf(date2);
//java.sql.Timestamp sqlDate2 = new java.sql.Timestamp(timestamp);
//sql_statement.setTimestamp(1, ts2);
As you can see my code is messy as I'm trying to solve this problem. I'm always getting an error in eclipse:
java.text.ParseException: Unparseable date: "8/10/2014 16:59"

and diff error shows up"

Anyone can help on why the date is unparseable? and how to convert it to a proper sql timestamp? thank you
Your fromFormat format specifier is
dd/MM/yyyy hh:mm
but should be
dd/MM/yyyy HH:mm
And change the toFormat to yyyy-MM-dd HH:mm:ss.SSSSSS
Then your parse code should change from
date2 = toFormat.parse(test);
to
date2 = fromFormat.parse(test);
System.out.println(toFormat.format(date2));
And I get the output
2014-10-08 04:59:00.000000
Please use following code it will serve your need
String test = "8/10/2014 16:59";
Date date2 = null;
SimpleDateFormat fromFormat = new SimpleDateFormat("dd/MM/yyyy hh:mm");
try
{
date2 = fromFormat.parse(test);
Timestamp tt = new Timestamp(date2.getTime());
System.out.println(tt);
} catch (ParseException ex)
{
date2 = null;
}
When you parse a date-string that looks like this:
String test = "8/10/2014 16:59";
you're using 24-hours format (16:59) you should use HH instead of hh.
See the following code snippet:
DateFormat fromFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm");
fromFormat.setLenient(false);
Date date2 = null;
try {
date2 = fromFormat.parse(test);
System.out.println("date2 = " + date2); // prints date2 = Wed Oct 08 16:59:00 PDT 2014
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
So you have a String, and you want to parse it as a Date... Let's see if this example helps you:
import java.util.Date;
import java.text.SimpleDateFormat;
import java.text.ParseException;
public class DateConverter
{
public static void main(String[] args) {
String test = "8/10/2014 16:59";
SimpleDateFormat sdf1 = new SimpleDateFormat("d/MM/yyyy HH:mm"),
sdf2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
/*
'sdf1' will be used to parse your input string as a date
'sdf2' will be used to output a string with your desired date format
*/
Date d;
String formatted_date;
try {
// Parse the string to a date, using the defined format
d = sdf1.parse(test);
// Now, format the date with 'sdf2' and store it in a string
formatted_date = sdf2.format(d);
System.out.println(formatted_date); // The output is: 2014-10-08 16:59:00
} catch(ParseException e) {
System.err.println(e.getMessage());
e.printStackTrace(System.err);
}
}
}
Was able to fix it using the code below:
DateFormat fromFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm");
Date date2 = null;
String def = perRow[cnt].replaceAll("8", "08");
try {
date2 = fromFormat.parse(def);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
long tsTime1 = date2.getTime();
java.sql.Timestamp sqlDate2 = new java.sql.Timestamp(tsTime1);
sql_statement.setTimestamp(2, sqlDate2);
Of course, I don't know if this is the correct or proer way to it as:
1. replace the sting with correct day 'dd'
2. parse to date format
3. convert to long
4. convert to sql date
Anyone knows a better way or idea, thread is open for comments. thank you.
You can convert it using java.sql.Timestamp. Here is a snippet:
String strDate = "15/07/1989 15:30";
SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy hh:mm");
Date date = format.parse(strDate);
System.out.println(date);
java.sql.Timestamp timestamp = new java.sql.Timestamp(date.getTime());
System.out.println(timestamp);
And the output will be:
Sat Jul 15 15:30:00 IST 1989
1989-07-15 15:30:00.0
Simple!
First parse fromDate then format in toDate pattern.
toFormat.format(fromFormat.parse(test));
I am trying to convert a date string of format dd.MM.YYYY into date object as following:
String start_dt = "01.01.2011";
DateFormat formatter = new SimpleDateFormat("dd.MM.YYYY");
Date date = (Date)formatter.parse(start_dt);
System.out.print("Date is : "+date);
But I am getting this result Date is : Sun Dec 26 00:00:00 MST 2010
I tried it in different ides and even on compileonline.com , still same result.
So Am I doing anything wrong here, because its not suppose to behave like this.
Please help.
The pattern for year is incorrect. You need to say:
DateFormat formatter = new SimpleDateFormat("dd.MM.yyyy");
The correct representation is yyyy
String start_dt = "01.01.2011";
DateFormat formatter = new SimpleDateFormat("dd.MM.yyyy");
Date date = null;
try {
date = (Date)formatter.parse(start_dt);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.print("Date is : "+date);
public static void main(String[] args) {
try {
String start_dt = "01.01.2011";
DateFormat formatter = new SimpleDateFormat("dd.MM.yyyy");
Date date = (Date)formatter.parse(start_dt);
System.out.print("Date is : "+date);
} catch (ParseException ex) {
Logger.getLogger(NewClass.class.getName()).log(Level.SEVERE, null, ex);
}
}
you should learn about DateFormat from here link1 and link2, you will realize that your code should be like that (year should be written in small letters).
String start_dt = "01.01.2011";
DateFormat formatter = new SimpleDateFormat("dd.MM.yyyy");
Date date = (Date)formatter.parse(start_dt);
System.out.print("Date is : "+date);
String myDate = new String("2011-06-23T00:00:00");
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
this.thedate = format.parse(myDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I'm not sure what I'm doing, but I have a timestamp that will be a string and I want to parse out the year and month. This is what I have so far.
You need to use "yyyy-MM-dd'T'HH:mm:ss" as a pattern for the SimpleDateFormat:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
I guess format should be this:
format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
