As this has nothing to do with Servlets, it's been moved to a more appropriate location.

Use SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy h:mm");
Date date = format.parse("25/10/2010 1:09");


For more information on the argument for SimpleDateFormat see the link

Date only has a format for debugging purposes. You can use the DateFormat to get it in format that you want.

First of all, there is an error in line 7 of your code:

This should have been:

Note that you must use "MM" for the month, not "mm", because "mm" means minutes.

Note that a Date object does not know anything about formatting by itself. If you print a Date object like you are doing in line 9 of your code, then a default format will be used to convert the Date to a String for display. If you want the date to be printed in a specific format, you must use the SimpleDateFormat object again to convert it to a string in the desired format:

Hi Jasper,

Appreciate your response.

Yeah when i format it again it will change to String which cannot be inserted into database because the data field is datetime type.

All I want is converting the String to datetime type so that i can insert into database (MS SQL).

Use a PreparedStatement and its setTimestamp method:
That way there will be no problems with the formatting.
