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));

In Android all Date objects are given in this type of date format "Mon Dec 03 00:13:21 GMT+05:30 2018" when you convert it with SimpleDateFormat.
Is there any possibility of getting a Date object in the "dd-mm-yyyy" format in Android?

You could set the pattern on a SimpleDateFormat and format the date:
new SimpleDateFormat("dd-mm-yyyy").format(new Date());

You could convert Strings into Dates as the following:
String pattern = "dd-mm-yyyy";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
String strDate = simpleDateFormat.format(new Date());//firstly get formatted str
Date newDate = simpleDateFormat.parse(strDate);//then get date object with wanted format

Get current date in YYYY-MM-DD format in Java (Android) [duplicate]

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

how to convert string date to java.util.date in java .
String date="12-12-2014 10:00:00"
Date d=2014-12-12 10:00:00;
Need this string date in date formate

Try this:
String date = "12-12-2014 10:00:00";
DateFormat inputDateFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss");
DateFormat outputDateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
System.out.println(outputDateFormat.format(inputDateFormat.parse(date)));
Output:
2014-12-12 10:00:00
Basically you need to parse your date in the format provided and from one format (inputDateFormat) you need to convert it to the other format (done by outputDateFormat).

Try following code:
String test="12-12-2014 10:00:00";
Date date=new SimpleDateFormat("dd-MM-yyyy HH:mm:ss").parse(test);
String OutputDate=new SimpleDateFormat("yyyy-dd-MM HH:mm:ss").format(date);
System.out.println(OutputDate);
Output :
2014-12-12 10:00:00

Get Date Object with formatted date [duplicate]

Java string to date conversion

I have a Date() object which always gives me date in a particular format (Comes in-built with Java). I want to get store Date in a specified format ("MMMM, dd yyyy HH:mm:ss"). I cam across one similar approach to do that-
Date date = new Date();
String dateFormat = "MMMM, dd yyyy HH:mm:ss";
SimpleDateFormat dt1 = new SimpleDateFormat(dateFormat);
dt1.format(date);
dt1.format(date) returns a formatted date in String data type. I want something similar which will return formatted date in Date data type.

I want something similar which will return formatted date in Date data type.
That is not possible. Date objects do not have a format by themselves, you cannot have a Date object in a specific format. You'll have to find another way to do what you need to do.

Your question is very unclear but I suspect what you want is parse a given String with a date into a Date object? If that is so, this should help: Java string to date conversion.
Given your example code, it would look like this:
String dateString = "June, 01 2014 08:23:51";
String dateFormat = "MMMM, dd yyyy HH:mm:ss";
Date date = new SimpleDateFormat(dateFormat, Locale.ENGLISH).parse(dateString);
