How do I format JDateChooser into dd-mm-yyyy?

I am trying to output the current date format into:
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");, but it is outputting like this:
Fri Dec 02 14:03:59 AEST 2016
Here is my code:
JDateChooser datePurchased = new JDateChooser();
DateFormat dateFormat = new SimpleDateFormat("dd-mm-yyyy");
Date newDate = new Date();
datePurchased.setDate(newDate);
I am now printing the result like this:
System.out.println(newDate.toString());
But this does not print out what I want, as per above.
My goal output is: 02/12/2016, how do I go about doing this, I've tried looking around but I cannot find the likes to solve my problem.
Thank you in advance.

The first part is simple enough, a Date is a representation in epoch time and doesn't have a modifiable format. Instead, you format it when you want to display it (or otherwise obtain a String representation). Additionally, you need M for months (m is minutes) and if you want / use that instead of -. For example,
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date newDate = new Date();
System.out.println(dateFormat.format(newDate));

You are printing the date but no using the formatter, you need to do:
String pattern = "dd-MM-yyyy";
DateFormat formatter = new SimpleDateFormat(pattern);
System.out.println(formatter.format(newDate));
edit:
if your goal output is: 02/12/2016
then in the pattern in the format incorrect, you will need to use slash and not hyphens
use instead dd/mm/yyyy

Use this simple code:
bill_date.setDateFormatString("yyyy-MM-dd");
In here bill_date is instance of the JDateChooser.

Oneliner to get a string representation of Day of week, day of month and time according to default locale

I'm using a combination of DateFormat and SimpleDateFormat to achive following string from a Date object:
fre 20 22:48
This snippet produces the outcome above:
DateFormat localizedTimeFormatter = DateFormat.getTimeInstance(DateFormat.SHORT, Locale.getDefault());
String str = new SimpleDateFormat("EE d", Locale.getDefault()).format(date) + " " + localizedTimeFormatter.format(date);
The outcome is exactly as I want, but I think there are improvements that could be done. I would like to use only the SimpleDateFormat to achieve this and getting shortname for day in week and day of month are not the problem. The problem is getting time in only hours and minutes according to locale, or more correctly, 12 or 24 hour format. I've checked out the documentation on the SimpleDateFormat Javadoc SimpleDateFormat
but as I can see there are no way of getting a time(hhmm) in 12 or 24hour format just by setting a format string to the SimpleDateFormat? Are there any way to achieve this by only using SimpleDateFormat as a oneliner, or do I have to do it the way I have done already, or are there a completely different way of solving this little issue?

How about
SimpleDateFormat sdf = new SimpleDateFormat("EE d HH:mm", Locale.getDefault());
or
SimpleDateFormat sdf = new SimpleDateFormat("EE d hh:mm", Locale.getDefault());

Your method is on the right track.
However, I didn't need to use the DateFormatter.
I got your expected result in this line itself.
String str = new SimpleDateFormat("EEE, d, k:m", Locale.getDefault()).format(Calendar.getInstance().getTime());
Output is:
Mon, 30, 19:5
The pattern you use in the first argument to SimpleDateFormat is the key here I think.
The meaning of the individual alphabets and their combination is already mentioned in the link you gave.
Hope this helps.

SimpleDateFormat parsing date string incorrectly

I'm trying to parse a String into a Date and then format that Date into a different String format for outputting.
My date formatting code is as follows:
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat dateParser = new SimpleDateFormat("d/M/yyyy h:m:s a");
String formattedDocumentDate = dateFormatter.format(dateParser.parse(sysObj.getString("document_date")));
The result of sysObj.getString("document_date") is 1/31/2013 12:00:01 AM. And when I check the value of formattedDocumentDate I get 01/07/2015.
Any help is much appreciated.

You are parsing days 31 as months. SimpleDateFormat tries to give you a valid date. Therefore It adds to 1/0/2013 31 months. This is 2 years and 7 month. So you get your result 01/07/2015. So SimpleDateFormat works correct.
One solution for you is to change your date pattern to M/d/yyyy h:m:s a or your input data.
To avoid these tries you have to switch off SimpleDateFormat lenient mode. Then you will get an exception if the format does not fit.

It looks like your input format is actually months first, then days. So should be "MM/dd/yyyy".
So:
SimpleDateFormat dateFormatter = new SimpleDateFormat("dd/M/yyyy");
SimpleDateFormat dateParser = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a");
String formattedDocumentDate = dateFormatter.format(dateParser.parse(sysObj.getString("document_date")));

Another example like this
SimpleDateFormat sdfInput = new SimpleDateFormat("yyyyMMdd");
System.out.println("date is:"+new java.sql.Date( sdfInput.parse("20164129").getTime() ));
Output is: 2019-05-29
I expect to throw parse exception but not (41)is not a valid month value.
on the other hand if I gave 20170229, system can recognize the February of 2017 doesn't have a lap year and return 2017-03-01 interesting.

Date converter in JAVA [duplicate]

This question already has answers here:
How to parse a date? [duplicate]

Closed 9 years ago.
I have date like Tue Mar 19 00:41:00 GMT 2013, how to convert it to 2013-03-19 06:13:00?
final DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
final Date date = bdate;
Date ndate = formatter.parse(formatter.format(date));
System.out.println(ndate);
gives the same date.

Use two SimpleDateFormat objects with appropriate formats and use the first to parse the string into a date and the second to format the date into a string again.

As the first answer says. First parse your date with SimpleDateFormat like this:
Date from = new SimpleDateFormat("E M d hh:mm:ss z yyyy").parse("Tue Mar 19 00:41:00 GMT 2013");
Then use that to format the resulting date object with another instance of SimpleDateFormat like this:
String to = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(from);
See the javadoc of SimpleDateFormat here. Hope that helps.

One major thing that the others have left out is dealing with the timezone (TZ). Anytime you use a SimpleDateFormat to go to/from a string representation of the date, you really need to be aware of what TZ you're dealing with. Unless you explicitly set the TZ on the SimpleDateFormat, it will use the default TZ when formatting/parsing. Unless you only deal with date strings in the default timezone, you'll run into problems.
Your input date is representing a date in GMT. Assuming that you also want the output to be formatted as GMT, you need to make sure to set the TZ on the SimpleDateFormat:
public static void main(String[] args) throws Exception
{
String inputDate = "Tue Mar 19 00:41:00 GMT 2013";
// Initialize with format of input
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
// Configure the TZ on the date formatter. Not sure why it doesn't get set
// automatically when parsing the date since the input includes the TZ name,
// but it doesn't. One of many reasons to use Joda instead
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
Date date = sdf.parse(inputDate);
// re-initialize the pattern with format of desired output. Alternatively,
// you could use a new SimpleDateFormat instance as long as you set the TZ
// correctly
sdf.applyPattern("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(date));
}

Use SimpleDateFormat in this way:
final DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
final Date date = new Date();
System.out.println(formatter.format(date));

If you do any calculations or parsing with dates please use JodaTime because the standard JAVA date support is really buggy

java Date and time format

how to format "2011-10-25T13:00:00Z" string into date and time
i used simple date format class
SimpleDateFormat sim=new SimpleDateFormat("yyyy-MM-dd");
but it only giving the date value. not time values
please help me to solve this problem

Use the format "yyyy-MM-dd'T'HH:mm:ss'Z'" for parsing this date format. See the documentation of SimpleDateFormat for more info. Code will look like this
String dateStr = "2011-09-19T15:57:11Z";
String pattern = "yyyy-MM-dd'T'HH:mm:ss'Z'";
Date date = new SimpleDateFormat(pattern).parse(dateStr);

This is because "yyyy-MM-dd" only mentions year (yyyy), month (MM) and date (dd). Try adding hh:mm if you want hours and minutes.
Example:
SimpleDateFormat sim = new SimpleDateFormat("yyyy-MM-dd hh:mm");
System.out.println(sim.format(new Date())); // prints "2011-10-27 01:56"
The full documentation of the format-string and its parts is found here. The documentation includes this example:
"yyyy-MM-dd'T'HH:mm:ss.SSSZ" - 2001-07-04T12:08:56.235-0700
Perhaps it's something like that you're looking for.
