I am trying to get the current date in a Talend job and I am using this as my context variable:
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Date date = new Date();
context.dateout = dateFormat.format(date);
System.out.println(context.dateout);
However, the type of the result is a String and not a Date.
How should I correct it?
Thank you very much!!
Try to do that according the following code:
String string = "2016-03-15";
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
try {
Date date = dateFormat.parse(string);
System.out.println(date);
} catch (ParseException ex) {
System.out.println(ex);
}
I don't know what your context.dateout means.
Note the difference between parse and format.
This is to create a string from a date:
dateFormat.format(date);
This is to create a date from a string:
dateFormat.parse(dateString);

I am getting response string 2018-10-03T09:00:36.845+0000
and i have to parse it for PrettyTime some min ago .
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
its not working, can you tell me Dateformat string to add in SimpleDateFormat ?
Here is My code
:
try {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
long time = sdf.parse(device_for_bottomviews.get(i).lastupdate).getTime();
PrettyTime prettyTime = new PrettyTime(Locale.getDefault());
String ago = prettyTime.format(new Date(time));
lastupdate.setText(ago);
}
catch (Exception e)
{
e.printStackTrace();
lastupdate.setText(device_for_bottomviews.get(i).lastupdate);
}
exception i am getting

You can use this format as pattern
yyyy-MM-dd'T'HH:mm:ss.SSSX
You don't need to quote the 'zone' part of the date format string, here is a corrected version:
"yyyy-MM-dd'T'HH:mm:ss.SSSZ"
I am trying to convert string value to date but its not working
Date dat1;
System.out.println("String date is "+tdate);// this shows 20141015
try{
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
dat1 = dateFormat.parse(tdate);
}
catch(Exception e){
System.out.println("error");
}
tdate is String variable. The code did not show any error it runs fine but
it prints error of catch block and does not execute the code in try
please help thanks.
Use this
SimpleDateFormat formatter = new SimpleDateFormat("yyyyMMdd");
Date date = formatter.parse(tdate);
The format does not match the way the date is written. Use this instead:
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
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:

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);
I have a date in(string) in dd-mon-yyyy format and I want to compare this date with system date.
eg.
I have 12-OCT-2010
and I want to compere this with system date in same format
You can use the SystemDateFormat class to parse your String, for example
final DateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
final Date input = fmt.parse("12-OCT-2010");
if (input.before(new Date()) {
// do something
}
Note that SimpleDateFormat is not threadsafe, so needs to be wrapped in a ThreadLocal if you have more than one thread accessing your code.
You may also be interested in Joda, which provides a better date API
Use SimpleDateFormat http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html
SimpleDateFormat f = new SimpleDateFormat("dd-MMM-yyyy");
String d = "12-OCT-2010";
try {
Date formatted = f.parse(d);
Date sysDate = new Date();
System.out.println(formatted);
System.out.println(sysDate);
if(formatted.before(sysDate)){
System.out.println("Formatted Date is older");
}
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I would recommend using Joda Time. You can parse that String into a LocalDate object very simply, and then construct another LocalDate from the system clock. You can then compare these dates.
Using simpledateformat -
String df = "dd-MMM-yyyy";
SimpleDateFormat sdf = new SimpleDateFormat(df);
Calendar cal = Calendar.getInstance();
/* system date */
String systemdate = sdf.format(cal.getTime());
/* the date you want to compare in string format */
String yourdate = "12-Oct-2010";
Date ydate = null;
try {
ydate = sdf.parse(yourdate);
} catch (ParseException e) {
e.printStackTrace();
}
yourdate = sdf.format(ydate);
System.out.println(systemdate.equals(yourdate) ? "true" : "false");
