Problems handling the Date Class.

[Vic Hood]

Hi all,
I had a doubt while trying to manipulate the Date class.I'm retreiving values from the database that are of the form "dd-MMM-yyyy" e.g 06-Jun-2011 .The problem causing code is as below
.

String strdateVar=	rs.getString("REP_DATE");//Output of the Form dd-MMM-yyyy(06-Jun-2011)
System.out.println("Before formatting"+strdateVar);
SimpleDateFormat d1=new SimpleDateFormat("dd-MMM-yyyy");
Date dtVar=d1.parse(strdateVar);
System.out.println("Before setting to bean Date--"+dtVar);// Value is of form Mon Jun 06 00:00:00 IST 2011

Any idea on how I could convert the value in dtVar to the same as that of strdateVar??As the value of dtVar needs to be set into a bean of return type Date.
Thank you for your time.

Note - if you are going to do any date type comparisons you will normally do better to compare java.util.Date objects than String objects.

uh I didnt quite get you .Can you please explain in code the point of using a second SimpleDateFormat instance?

dtVar and strdateVar have the same values. Its just the representation that is different.

As dtVar is a Date object, you can use it directly to set the values of the bean property.

yes ,Sure if it had the right value , if you read my post correctly ..
the value of strdateVar is --06-Jun-2011
The value of dtVar is of the form --Mon Jun 06 00:00:00 IST 2011
So you see I cant use it??

I really don't understand what you are trying to do! java.utl.Date objects store the date as the number of millisecoonds since 1/1/1970 00:00:00 UTC. The value you get from the toString() method is just a human readable form of the date and does not in any way reflect how the data is stored in the java.util.Date.

What are you trying to do?

I dont see how they are different. 06-Jun-2011 and Mon Jun 06 00:00:00 IST 2011 both mean the 6th of June, 2011. Run the below snippet and see the output.

String strdateVar=	rs.getString("REP_DATE");//Output of the Form dd-MMM-yyyy(06-Jun-2011)
System.out.println("Before formatting"+strdateVar);
SimpleDateFormat d1=new SimpleDateFormat("dd-MMM-yyyy");
Date dtVar=d1.parse(strdateVar);
System.out.println("Before setting to bean Date--"+d1.format(dtVar));// Output is 06-Jun-2011

dtVar, like James mentioned, contains the value that you want as a Date object.
