Closed 9 years ago.
I have a string and i need to convert it to date in the "YYYY-mm-dd" format which i'm unable to do. I checked the similar post on stckoverflow but didnt help so i'm posting this query.
String stringDate = "Dec 13, 2013";
I need this to be convert to
Date reportDate = 2013-12-13";
when i use simpledateformat i got unparsable date. Please help
Check this out:
try {
SimpleDateFormat format1 = new SimpleDateFormat("MMM dd, yyyy");
SimpleDateFormat format2 = new SimpleDateFormat("yyyy-MM-dd");
String stringDate = "Dec 13, 2013";
Date date = format1.parse(stringDate);
System.out.println(format2.format(date));
} catch (ParseException exp) {
// Take appropriate action
}
Output: 2013-12-13
In programming a very important skill is taking information that is close to what you need and using it to find what you do need.
Look at the link in the comments and you can see:
http://download.oracle.com/javase/1.5.0/docs/api/java/text/SimpleDateFormat.html
Read that and you have what you need to adjust the answer there to give the results you want.
Use SimpleDateFormat as here:
new_date is your Date
String stringDate = "Dec 13, 2013";
SimpleDateFormat format = new SimpleDateFormat("YYYY-MM-DD");
Date new_date=format.parse(stringDate);
String date="Your date";
SimpleDateFormat format = new SimpleDateFormat("MMM DD, YYYY");
Date d= format.parse(date);
DateFormat newFormat = new SimpleDateFormat("YYYY-MM-DD");
System.out.println(newFormat.format(d));
I would do something like:
SimpleDateFormat parser = new SimpleDateFormat("MMM dd, yyyy");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date reportDate = parser.parse(stringDate)
String result = formatter.format(reportDate);

Change date format in a Java string

I was trying to convert date string 08-12-2017 to 2017-12-08(LocalDate). Here is what I tried-
String startDateString = "08-12-2017";
LocalDate date = LocalDate.parse(startDateString);
System.out.println(date);
Also tried using formatter, but getting same result, an DateTimeParseException.
How can I get an output like 2017-12-08, without getting an exception?
Try this (see update below)
try {
String startDateString = "08-12-2017";
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(sdf2.format(sdf.parse(startDateString)));
} catch (ParseException e) {
e.printStackTrace();
}
Update - Java 8
String startDateString = "08-12-2017";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");
DateTimeFormatter formatter2 = DateTimeFormatter.ofPattern("yyyy-MM-dd");
System.out.println(LocalDate.parse(startDateString, formatter).format(formatter2));
First you have to parse the string representation of your date-time into a Date object.
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = (Date)formatter.parse("2011-11-29 12:34:25");
Then you format the Date object back into a String in your preferred format.
DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
String mydate = dateFormat.format(date);

I have a date in the format 11-NOV-13
When i convert the date i get the value Sat Nov 11 00:00:00 IST 13.
But i want the converted date to be in the format Sat Nov 11 00:00:00 IST 2013.
Though i have used the dateformat it is not taking it. Can anyone point me where i am wrong?
Below is the code i have been working on
DateFormat format = new SimpleDateFormat("dd-MMM-yyyy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
Change the format to:
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
You need to make the year 2 numbers:
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
You can reference the docs here.
As you are not providing the full year you need
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
System.out.println(myDate);
Change to this format:
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
DateFormat format = new SimpleDateFormat("dd-MMM-yy", Locale.ENGLISH);
Date myDate = format.parse("11-NOV-13");
String formattedDate = sdf.format(myDate);
I have this:
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
Date result = dateFormat.parse(this.getCreatedTime());
Basically I want to convert a string like "2016-09-27T09:19:57Z" into something like "September 27, 2016 at 9:19 AM".
If I use the code above I end up with a Date object, but all the methods are deprecated. So how do I achieve this?
You can use DateFormat again as #Thomas wrote:
DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
Date inputDate = inputFormat.parse(this.getCreatedTime());
DateFormat outputFormat = new SimpleDateFormat("outputFormat");
String output = outputFormat.format(inputDate);
You should do research before posting any question here.
Use this to get Date from your required pattern
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());
Date date = null;
try {
date = format.parse(unformattedDate);
} catch (ParseException e) {
e.printStackTrace();
}
Make new instance of your desired patter.
format = new SimpleDateFormat("MMMM dd, yyyy 'at' HH:mm a", Locale.getDefault());
String formattedDate = format.format(date);

I have date in string object. I want to convert into Date object.
Date getDateFmString(String dateString)
{
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date convertedCurrentDate = sdf.parse(dateString);
return convertedCurrentDate ;
}
above function returning following output.
Fri Apr 22 00:00:00 IST 2016
but I want output in this format '2016-03-01' only
function should take string only.
function should return Date object.
I have done lot of research over web, but I got solution from one Expert.
Date getDateFrmString(String dDate)
{
java.sql.Date dDate = new java.sql.Date(new SimpleDateFormat("yyyy-MM-dd").parse(sDate).getTime());
return dDate;
}
this is what I want.
Change the date format from
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
to
SimpleDateFormat sdf = new SimpleDateFormat("dd-mm-yyyy");
Hope this works
See this example
public Class DateFormatDemo{
public static void main (String args[]) {
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy);
String dateInString = "01/01/2015";
try{
Date date = formatter.parse(dateInString);
System.out.println(date);
System.out.println(formatter.format(date));
}catch(ParseException e){
e.printStackTrace();
}
}
}
This link might help you with string to date object conversions
You are parsing with the wrong format try
String dateString="01-01-2016";
SimpleDateFormat sdfP = new SimpleDateFormat("dd-MM-yyyy");
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date convertedCurrentDate = sdfP .parse(dateString);
String date=sdf.format(convertedCurrentDate );
System.out.println(date);
Output:
2016-01-01
DEMO1
And if you want the format to dd-MM-yyyy then no need to define seperate SimpleDateFormat object.
String dateString="01-01-2016";
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
Date convertedCurrentDate = sdf.parse(dateString);
String date=sdf.format(convertedCurrentDate );
System.out.println(date);
OUTPUT:
01-01-2016
DEMO2
To format the string date you have to first parse the String to Date object using the same format of date which the String have then format it using the desired format as seen in the above code.
Date objects don't have a format. Only a String does. A Date object will be output with whatever format you tell it to be format as. It all depends on what the format of the DateFormat object is when you call .format(). Calling the toString() method on a Date object uses a DateFormat of "dow mon dd hh:mm:ss zzz yyyy".
Let's do it step by step:
You have a date as String in dd-MM-yyyy format.
You want to convert it into date. (for this you are using SimpleDateFormat)
Now you are printing the date. Question here is are you printing the converted date object or input string?
If its a date object then toString method is called of date class.
As per comment on java.util.Date class it's:
dow mon dd hh:mm:ss zzz yyyy
similar to
Fri Apr 22 00:00:00 IST 2016
So that coincides with what you get in output in the second approach. But how is that code even running is strange.
String inputStr = "11-11-2012";
DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date inputDate = dateFormat.parse(input);
Variable 'input' is not defined.
What are the possible solutions:
While printing date, convert it back to String using SimpleDateFormat as per the requirement.
Date d =new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String dStr = sdf.format(dateString);
System.out.printn(dStr);
Extending class java.util.Date and override toString, but that would be a bad idea.

how can i make Date data type from String in java?
input: String "2014/01/01 18:02:02" => output: Date 2014/01/01 18:02:02
You could use a DateFormat to parse and format (they're reciprocal functions) the String. Something like,
String str = "2014/01/01 18:02:02";
DateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
try {
Date d = df.parse(str);
System.out.println(df.format(d));
} catch (ParseException e) {
e.printStackTrace();
}
Output is (as requested)
2014/01/01 18:02:02
please use SimpleDateFormat to parse String To Date.
In there you can find suitable DateFormat to convert this String to Date.
you can try this
String dateString = "2014/01/01 18:02:02";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");
LocalDateTime StringAsDate = LocalDateTime.parse(dateString, formatter);
I would recommend using Time(java.time) API instead of java.util for your Date & Time needs as it is new and exclusively added to java for Date & Time operations.
You can use the following code snippet -
String dateString = "10-11-2014";
DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date inputDate = dateFormat.parse(dateString);
You can try this too.
SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
String dateInString = "2014/01/01 18:02:02";
Date date = formatter.parse(dateInString);
System.out.println(date);
System.out.println(formatter.format(date));
It is a working and it is also suitable to you as it is not complicated. you will get this output:
Wed Jan 01 18:02:02 IST 2014
2014/01/01 18:02:02
For your date following code should work :-
String myString = "2014/01/01 18:02:02";
DateFormat myDateFormat = new SimpleDateFormat("yyyy/MM/dd hh:mm:ss");
Date myDate = myDateFormat.parse(myString);
For more details, see the documentation for SimpleDateFormat. Just make sure you use capital "MM" for month and small "mm" for minute.
