java date format yyyy-mm-dd.hh.MM.ss.ms
(3 answers)
Closed 5 years ago.
I am trying to parse the date from a given String. My input string is 2017-08-11, which represents Aug 11th 2017 (Basically yyyy-mm-dd format)
However if I run
new SimpleDateFormat("yyyy-mm-dd").parse("2017-08-11")
I get Wed Jan 11 00:08:00 GMT 2017
Why is this? I have created a test program at: http://ideone.com/dHe0ZA
M (capital M) represents month and m (small m) represents minute in java.
So the format you have specified is wrong.
Try
new SimpleDateFormat("yyyy-MM-dd").parse("2017-08-11")
You can see more details about the formats here.

Java SimpleDateFormat always returning January for Month

i tried to convert a date String into a date object, but unfortunately the month is set every time to Jan and I can't figure out why.
String date = "20190522T072424.000Z";
DateFormat sdf = new SimpleDateFormat("yyyyMMDD'T'HHmmss.SSS'Z'");
System.out.println(sdf.parse(date));
Output: Tue Jan 22 07:24:24 CET 2019
As AxelH said, the format DD is for day of the year. If you use yyyyMMdd'T'HHmmss.SSS'Z' you will print Wed May 22 07:24:24 WEST 2019.

I am currently facing a problem when it comes to some Java methods that weren't explained to me in lectures very well. I need to write a program that accepts user-inputted strings (particularly a date) in yyyymmddhhss format, which should then convert to hh:mm Month day, year.
E.g. 201901151500 outputs: "03:00 PM January 15, 2019".
Currently, in my program, I have accepted the user's input and implemented a method that returns an error message if the inputted format is invalid.
Any tips on where to go from here? Advice is greatly appreciated-- thank you!
If you are using Java 8 you can use java.time API like so :
String input = "201901151500";
LocalDateTime dt = LocalDateTime.parse(input, DateTimeFormatter.ofPattern("uuuuMMddHHmm"));
String output = dt.format(DateTimeFormatter.ofPattern("hh:mm a MMMM dd, uuuu"));
>> output = 03:00 PM janvier 15, 2019
Use the DateTimeFormatter as defined here: https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html
Pay attention to the parse method. You can define a formatter that takes in a string and then returns it in a certain way, almost any way you choose.
Here is the LocalDataTime class:
https://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html
Example code:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
LocalDateTime local = LocalDateTime.parse("2004 12 25", formatter);

Change the format of Date Java [closed]

I have the following piece of code:
System.out.println(array[9]);
Date d = df.parse(array[9]);
System.out.println(d.toString());
and the result of this looks like the following:
01.01.2017
Sun Jan 01 00:00:00 CET 2017
My DateFormatter:
DateFormat df = new SimpleDateFormat("dd.MM.yyyy",Locale.GERMANY);
So my question is now why I get the wrong format.
First result is a string, which I must convert to date.
But I got the wrong format, not the German one (dd.MM.yyyy).
What's wrong?
In your example you should use df.format(d) if you plan to convert Date to String. The default Date.toString() method will use the predefined format which you can't control.

I have the output
Mon Feb 19 02:43:13 EST 2018
Which I've obtained from
System.out.println(new Date());//+ some adjustments with the calendar obviously.
I was curious how I would 'reload' the 'date' from the given output
Mon Feb 19 02:43:13 EST 2018
So if I wanted to refer to the date again when I reload my program, I want it to parse the String and set the date based off of those parameters, is this a good way to handle this?
The best idea I would have is storing the date in a document, I have done this in a similar fashion. I had taken the Unix epoch time, stored the value, then had a converter bring it back to the human readable version. Not too complex.

I get a date from a request with this format > 1413972425000
When I execute in JavaScript
new Date(1413972425000)
the result is
Wed Oct 22 2014 11:07:05 GMT+0100 (GMT Daylight Time)
So.. What I want is get the datetime but in Java and I don't know how can I do it.
Thanks.
1413972425000 isn't a int value. It is too large for int. You can use it as a long value. 1413972425000L
You can use
Date date=new Date(1413972425000L); // accept long value.
System.out.println(date);
You can use new Date(1413972425000L) to convert long to date. Note the appended L to the numeric value.
