Converting a String to Date

I have a String in which i am storing the date which I have retrieved from database. How can I convert this String to a Date object and use Comparator for sorting.
String strCreatedDate1 = ((CVendorEmployees) vendoremployee1).getCreatedDate().toUpperCase();The date format which I will retrieve from String is mm/dd/yyyy.
I want to convert this into date and use it for sorting.
Thanx.

Date dtTmp = new
SimpleDateFormat("dd-MM-yyyy").parse(((CVendorEmployee
s) vendoremployee1).getCreatedDate());
Calendar calendar = Calendar.getInstance();
calendar.setTime(dtTmp);
Now you have the date object do what ever you wish toBetter make thatnew SimpleDateFormat("MM/dd/yyyy")And no need for the Calendar stuff if all you want is a Date object.

How to convert a string to date and then compare it with todays date???

Hello.
I want to set a format first for my dates
DateFormate df = new SimpleDateFormate("yyyy-mm-dd");
once this is done then I want to convert any string to date object in the above formate
String str="2001-07-19";
Date d = null;
try{
d = df.parse(s);
}catch(ParseException pe) {
pe.printStackTrace();
First of all there is something wrong above,cus what I get for this is
Fri Jan 19 00:07:00 MST 2001
where as it should have been
2001-07-19... to my understanding.
once this part is done I need to get current date in the above set format and compare the
current date and the date I set.
I will appreciate the help.
Thanks

for the output part:
a date is a point in time
the output depends on the format you specify for output
using for example a SimpleDateFormat.
You only specified the format for parsing (which is independent for that of output) so java uses some default format ... see the DateFormat.format() method for details.
for the comparison stuff, I just posted a little code snippet in this forum a few minutes ago.
the hint is: Date.getTime() returns milliseconds after a fixed date

Problem in converting the String to Date with time zone GMT

Hi,
When I tried to convert the string 12/05/2009 to Date, the time zone is set to BST.On the other hand, for the date 12/12/2009, the time zone is set to GMT. What should I do to get the time zone as GMT all the time.?
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = "12/05/2009";
System.out.println(myDate.toString());

I think you are all missing the point. java.util.Date objects always alway always store the date as the number of milliseconds since 1/1/1970 UTC so the only TimeZone they have its the implicit UTC. When you use the Date.toString() method the toString() method gets the default time zone from your environment and formats the data accordingly. This means that the same Date object will, by default, produce a different result for France and Australia and the US.
So, if you have the date "12/5/2009" as a String then to convert it to a java.util.Date you must specify what TimeZone is implied. If it is your system time zone then you can just create a SimpleDateFormat object with the correct format and then use the parse() method to create the java.util.Date object and this will automatically be converted to UTC. If the date String represents some other time zone then you must explicitly set the time zone of the SimpleDateFormat object before parsing the string.
The same approach applies when converting a java.util.Date object to a String. If you want anything other than your system time zone then you must explicitly tell the SimpleDateFormat what time zone you want the result formatted for.

Red Line? Sounds ominous. I wonder what it means.

Convert from String to Date for storing in SQL Server 2000

Hi,
I've accepted some values from a user using a form in HTML.Now using Servlets I transfer the value to my java code .
I want to know how can I convert a DATE accepted from the user thats presently in "String" format to the "datetime" format for SQL Server2000.
Please guide me with some steps and I shall be grateful.
Thanks

The java.text.SImpleDateFormat class is most probably of use.
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
String enteredDate = "25/12/2006";
java.util.Date utilDate = sdf.parse(enteredDate);
java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());You can then use the java.sql.Date with the "setDate()" method of a prepared statement. This method would be database independant, as you are setting an actual date, not depending on a specific format on the database end.

Convert a string to date, so that i can insert it on SQL database

Hi, me again..
i have this variable
date.getText()
i want to convert it to date, so i did this:
d = (Date) DateFormat.parse(date.getText());
but it says "Cannot make a static reference to the non-static method parse(String) from the type DateFormat"
what the hell is that?
can someone help? i want the date to correspond to the variable format on my database (DATETIME (yyyy-mm-dd))

GMX750 wrote:
OK, like this?:

i did this, but the IDE says the same thing
: \If you don't know the difference between static and non-static methods, or how to instantiate an object, you're not ready to be messing with JDBC yet. Sorry if that sounds harsh, but it's the truth. If you keep trying to go down this path without getting a handle on the fundamentals, you're just setting yourself up for more frustration and a poor excuse for an education.

Hello,
The best way is to use the HEX to decimal coversion VI in the string pallette. Then, write this decimal directly to your chart. If you are doing it a point at a time put it into a while loop.

Convert a string to JAva.sql.date..

I am having a string with the value as follows..
String fval="03-10-2001"..
I am using this value in a rs.updateDate method where I need to convert it to a different format as
2001-10-03...can anybody give me the syntax..

You should hold dates as Date instances. But if you want to convert between Strings and Dates then you should use a DateFormat:
String originalDateString = "31-10-2001";
// Convert the original string to a date
DateFormat originalDateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = originalDateFormat.parse(originalDateString);
// Get a representation of the date in the new format
DateFormat newDateFormat = new SimpleDateFormat("yyyy-MM-dd");
String newDateString = newDateFormat.format(date);(Excuse the quirky formatting that the Java code filter applies!)
Hope this helps.

Converting String to Date

Hi All,
I am having a String value which is having date in the format 'Mon Apr 14 16:07:52 IST 2008'
Now I want to convert this String to Date with format 'mm/dd/yyyy' , to display as 04/14/2008
Also I want to add 5 days to this date and display the new date 04/19/2008
I don't know How to convert the string which is having date in 'Mon Apr 14 16:07:52 IST 2008' format to format I need.
Please help me.

Hi ,
I wrote a class that tries to parse a String Date and converts it to object. However, I found a very interesting thing while testing this code. I was trying to paarse "2008:03:04 16:21:05" string by using
DateFormat.getDateFromString(null,"2008:03:04 16:21:05" )
It should by pass all try loop accept the one with yyyy:MM:dd HH:mm:ss format. But it went inside the try loop which had MM:dd:yyyy HH:mm:ss format and gave me a wrong date object with year 0171, april 03.
Could any one help me to understand why it is happening? as a work around I put MM:dd:yyyy HH:mm:ss at the end of the program and it is giving me correct object as it did not have to go that far before matching the format.
Thanks,
AL-Amin
