Trouble parsing Java Date Object?

I am receiving a Java Date formatted like so: "Sun Sep 14 02:00:00 PDT 2014" into a yyyy-MM-dd format but I can't seem to parse it. What I tried is the following:
String time = "Sun Sep 14 02:00:00 PDT 2014";
SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd");
Date contractEffectiveDateFormat = f.parse(time);
System.out.println("Date: " + contractEffectiveDateFormat);
However, I get an error saying that this date is unparsable. I'm not sure how to go about parsing this date because if I try to parse the date using the following:
DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
which is how to actually parse the date correctly into a Date object,
the string would turn into a Date object, but I can't seem to do anything with it from there. I want to turn it in so that it looks like 2014-09-14. Any ideas on how to do so? Thanks!

Use two DateFormat(s) one for input and for output,
String time = "Sun Sep 14 02:00:00 PDT 2014";
DateFormat out = new SimpleDateFormat("yyyy-MM-dd");
DateFormat in = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
try {
Date effectiveDate = in.parse(time);
System.out.println("Date: " + out.format(effectiveDate));
} catch (ParseException e) {
e.printStackTrace();
}
Output is the requested
Date: 2014-09-14

Your incoming string is this String time = "Sun Sep 14 02:00:00 PDT 2014";
which means the SimpleDateFormat pattern should match the incoming String pattern so you need to use SimpleDateFormat like this
DateFormat inFormat=new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy",Locale.ENGLISH);
Then when you called parse() on inFormat it will give you Date Object which doesnot have particular format associated with it. So in order to format the Date again you need to create SimpleDateFormat object specifying the format you want which is this
DateFormat outFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
Ultimately bind all together
One more thing always specify the Locale
String time = "Sun Sep 14 02:00:00 PDT 2014";
DateFormat outFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
// good practice to specify the locale
DateFormat inFormat=new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy",Locale.ENGLISH);
try {
Date parsedDate = inFormat.parse(time);
System.out.println("Required Formatted Date: " + outFormat.format(effectiveDate));
} catch (ParseException e) {
e.printStackTrace();
}

Simply add another SimpleDateFormat that'll allow you to present the Date object the way you want:
public static void main(String[] args) throws ParseException {
String time = "Sun Sep 14 02:00:00 PDT 2014";
DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy");
Date contractEffectiveDateFormat = df.parse(time);
System.out.println("Date: " + contractEffectiveDateFormat);
SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(f.format(contractEffectiveDateFormat)); // prints 2014-09-14
}

Convert string to date Android

I'm trying to convert a String that represents a date stored in SQLITE.
The date was stored into sqlite as follows:
Date date;
date.toString();
According with Java documentation, toString() method:
Returns a string representation of this Date. The formatting is
equivalent to using a SimpleDateFormat with the format string "EEE MMM
dd HH:mm:ss zzz yyyy", which looks something like "Tue Jun 22 13:07:00
PDT 1999". The current default time zone and locale are used. If you
need control over the time zone or locale, use SimpleDateFormat
instead.
Until here, it's fine but, when I try to get the String and convert it to date again, Java throws an exception.
The String comes from sqlite:
Mon Jan 20 18:26:25 BRT 2014
So, I do:
SimpleDateFormat sdf = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy", Locale.US);
Date date= sdf.parse("Mon Jan 20 18:26:25 BRT 2014");
What I'm doing wrong?
Thanks.

try this code
String dateString = "here your date";
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date convertedDate = new Date();
try {
convertedDate = dateFormat.parse(dateString);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(convertedDate);

Try this:
String w = "Mon Jan 20 18:26:25 BRT 2014";
SimpleDateFormat pre = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzz yyyy");
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
try{
Date date = pre.parse(w);
System.out.println(sdf.format(date));
}catch(Exception e){
e.printStackTrace();
}
Output:
20/01/2014

Formatter for storing and restoring data value in format dd/MM/yyyy
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy");
Storing data
String dataAsString = simpleDateFormat.format(date); // 20/01/2014
Restoring data
Date data = simpleDateFormat.parse(dataAsString);

how to format time using java with flex?

I'm getting in flex String Sat Aug 4 13:10:00 GMT+0530 2012 so in my Java program I'm converting like this
try {
String str_date = "Sat Aug 4 13:10:00 GMT+0530 2012";
DateFormat formatter = new SimpleDateFormat(
"EEE MMM dd HH:mm:ss zzzz yyyy");
Date date = (Date) formatter.parse(str_date);
System.out.println(date);
} catch (ParseException e) {
System.out.println("Exception :" + e);
}
but it gives
`Exception :java.text.ParseException: Unparseable date: "Sat Aug 4 13:10:00 GMT+0530 2012"`

#Florent's answer is good, but since that was written Java has gained new date/time packages. This is one way to do it in Java 8 and later:
import java.time.format.DateTimeFormatter;
import java.time.LocalDateTime;
// ...
String input = "Sat Aug 4 13:10:00 GMT+0530 2012";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEE MMM dd HH:mm:ss 'GMT'Z yyyy");
LocalDateTime dateTime = LocalDateTime.parse(input, formatter);
The dateTime object can then be used for date/time calculations, or rendered as a string using another formatter, or whatever you need to do.

This formatter works:
DateFormat formatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss 'GMT'Z yyyy");

convert string into java.util.date format in java

am having a string like this.
Thu Oct 07 11:31:50 IST 2010
I want to convert this into its exact date time format to store it in SQL.
Am familiar with so many string to date conversions like the following.
String dateString = "2001/03/09";
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/mm/dd");
Date convertedDate = dateFormat.parse(dateString);
But i need to convert a string like Thu Oct 07 11:31:50 IST 2010
into its Date format with timestamp.
Can anyone explain the proper way of converting this into its java.util.Date format.?

Try this:
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy");
For future reference read up on the SimpleDateFormat class:
http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

Use this format -'EEE MMM dd HH:mm:ss z yyyy'
Date date = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy")
.parse("Thu Oct 07 11:31:50 IST 2010");
System.out.println(date);

Can't you do like below
String str = "Thu Oct 07 11:31:50 IST 2010";
SimpleDateFormat sdf = new SimpleDateFormat("E MMM dd hh:mm:ss 'IST' yyyy");
SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy/MM/dd");
System.out.println(sdf2.format(sdf.parse(str)));

Parse RSS pubDate to Date object in java

How can I parse a pubDate from a RSS feed to a Date object in java.
The format in the RSS feed:
Sat, 24 Apr 2010 14:01:00 GMT
What I have at the moment:
DateFormat dateFormat = DateFormat.getInstance();
Date pubDate = dateFormat.parse(item.getPubDate().getText());
But this code throws an ParseException with the message Unparseable date

You can define the date format you are trying to parse, using the class SimpleDateFormat:
DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz");
Date date = formatter.parse("Sat, 24 Apr 2010 14:01:00 GMT");
Additionally, for non-English Locale's, be sure to use the following when parsing dates in English:
new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz", Locale.ENGLISH);

If you need to have an RFC822 compliant date, try this :
DateFormat dateFormatterRssPubDate = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z", Locale.ENGLISH);

For the lucky one that can use the Java 8 LocalDateTime:
LocalDateTime localDateTime = LocalDateTime.from(DateTimeFormatter.RFC_1123_DATE_TIME.parse("Sat, 24 Apr 2010 14:01:00 GMT"));
