How to convert current date into string in java?
(9 answers)
Closed 6 years ago.
I really need your help. I have searched and tried every example I could use, but none have worked.
I need to store current date in YYYY-MM-DD format in a text file..the String date has to be a string..
String dateF = "YYYY-MM-DD";
Date dateOnly = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat(dateF);
String date = dateFormat.format(dateOnly);
when I tried that code above.. this the output I got
please|work|2016-04-110|11
please help me...this is my assignment due this Friday ): I just need this date and 2 other things to be done..
thanks :)
your issue comes from the case you used for Y and D. according to the API SimpleDateFormat documentation, you should use d (day in month) instead of D (day in year), in your format definition.
String dateF = "yyyy-MM-dd";
Format being used is incorrect.
YYYY-MM-DD : Capital DD will return Day in the year. So, 11 April corresponds to 110th day in the year.
yyyy-MM-dd : Small dd will return the Day in the month.
Refer: https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
Use this code :
Calendar c = Calendar.getInstance();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
String formattedDate = formatter.format(c.getTime());
The formattedDate contain 2016-04-19
Edit :
In your code change the YYYY to yyyy and DD to dd.

I‘m fetching dates which have the format yyyy-MM-dd.
I have these extracted as a string which would look like this:
String date = "2020-09-05";
Now I want to convert it into a EEE, d MMM yyyy format, so the result should be: Sat, 5 Sep 2020.
I tried reformatting it like this:
Date convertedDate = new SimpleDateFormat(EEE, d MMM yyyy).parse(date);
For some reason this and many tries to get around it all end up with a java.text.ParseException: Unparseable date "2020-09-05".
Can‘t I convert a date from a string like that? Is there a better way to reformat a string into other formats?
You need to make a distinction between parsing the date (turning a String into a Date or LocalDate class) and formatting a date (turning the Date or LocalDate class instance to a String).
To parse the initial string, use:
LocalDate convertedDate = LocalDate.parse(date)
To format the convertedDate, use:
String formattedDate = convertedDate.format(DateTimeFormatter.ofPattern("EEE, d MMM yyyy"))
EDIT: I am assuming you are at least on Java 8, so you can use the newer date/time classes. See https://www.baeldung.com/java-8-date-time-intro for some more info.
You are mixing up parsing and formatting: your code is trying to parse a string given the format. You’re telling Java you’re expecting the date to contain the week name.
You need to first parse your date in the format it’s in. This will give you a date. You next need format your date with the desired format, which will give you a string:
final String dateString = "2020-09-05";
final Date date = new SimpleDateFormat("y-M-d").parse(dateString);
final String converted = new SimpleDateFormat("E, d MMM y").format(date);
ok here's the code:
String sDate1="1998-12-31";
DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date date = sdf.parse(sDate1);
System.out.println("EEE, d MMM yyyy formatted date : " + new SimpleDateFormat("EEE, d MMM yyyy").format(date));

Month issue in SimpleDateFormat class
(6 answers)
Closed 5 years ago.
I am trying to get a Date object in the format YYYY-MM-DD representing the current system date. Below is my attempt:
Date todayDate = Calendar.getInstance().getTime();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-mm-dd");
String todayString = formatter.format(todayDate);
The values are as follows:
todayDate: Mon May 15 16:24:47 GMT+01:00 2017
todayString: 2017-24-15
Having tried this a couple of times I noticed the todayString is not made up of YYYY-MM-DD but YYYY-[minutes][minutes]-DD.
How might I get the current date in the YYYY-MM-DD format?
Change this:
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-mm-dd");
to this:
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
mm stands for the minutes, while MM (capitalized) stands for the month

Java: Date from unix timestamp
(11 answers)
Closed 6 years ago.
I am trying to get dd.MM.yyyy and hh:mm from 1436536800 but only the time is correct, the date is completely wrong. I don't really understand how this is supposed to work
int dt = time.getInt("start")*1000;
Date date = new Date(dt);
startDate = dateFormat.format(date);
If time.getInt("start") is a valid unix timestamp, you must add "000" to the number. Example: 1436536800 * 1000 = 1436536800000. Then you can use the timestamp to get a Date:
final Date date = new Date(Long.parseLong("1436536800000"));
SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy hh:mm");
System.out.println(sdf.format(date));
Console exit: 10.07.2015 09:00
Assuming the time is correct, it's likely the fact that you're multiplying by 1,000. When creating the date the way you are, it takes in milliseconds. Is it possible that your input is already in milliseconds? (Your current method will be ~2 minutes off if so)
Date date=new Date(1436536800);
SimpleDateFormat df2 = new SimpleDateFormat("dd.MM.yyyy");
String dateText = df2.format(date);
Date you are getting is a JSON string value. follow steps below to format it correctly.
First download Moment.js file and add it in your project.
var date1 = "1436536800"; // your long value contain in this variable.
var date2 = moment(date1).format(MMMM Do YYYY);//It will give you formatted date value.

Java Date Format for Locale
(2 answers)
Closed 9 years ago.
Sorry if my question has already been answered, but I can't really find what I am looking for.
So I have this time "1228061700000" and I want to convert it to show only the date, like this 17/6/08.
It would also be good to check for the locale, so for US locale the format to be like this 6/17/08 and for european locale to be 17/6/08... How can I do it?
Use a DateFormat:
DateFormat f = DateFormat.getDateInstance(DateFormat.SHORT, Locale.ENGLISH);
String result = f.format(new Date(millis));
long milliSeconds=1228061700000l;
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); //change your date time formate as required
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(milliSeconds);
System.out.println(formatter.format(calendar.getTime()));
DateFormat.getDateInstance(int style, Locale aLocale)This displays the current date in a locale-specific way.
So, you can try:
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, yourLocale);
String formattedDate = df.format(yourDate);
In this case you can choose what type of yourDate is.
Your locate can be changed to Locale.UK Locale.US and etc.

getting month name wrong with SimpleDateFormat
(2 answers)
Closed 9 years ago.
I want a timestamp field. I tried the below to get time in mmddyyyyhhmmss format.
All the fields give proper data but the month field has improper value.
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("mmddyyyyhhmmss");
String date = simpleDateFormat.format(new Date());
O/P I get is 13132013021331. What I expect is 03133013021331.
Your Month should be MM not mm
mm means Minutes
SimpleDateFormat mmddyyyy returns improper data for month
coz your format for month is wrong.
it should be:
new SimpleDateFormat("MMddyyyyhhmmss");
MM---> Month
mm---> minutes
You need this:
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMddyyyyhhmmss");
String date = simpleDateFormat.format(new Date());
You used "mm" twice - once for month (incorrect) and again for minutes (correct).
