Remove time part from java.util.Date()

[Mahesh Kedari]

Hi,
I want to get only the date part of java.util.Date() resetting time to 00.

Let me make it more clear. When I am initializing the date object as

java.util.Date date = new java.util.Date();

I am getting the date object with value as "Thu May 27 12:13:49 IST 2010"
I just want to set the time part of this object to "00:00:00"
I dont want to get the output as String using DateFormat class.
The output should be a java.util.Date object only.

In java.util.Date, setHours, setMinutes and setSeconds functions are deprecated.
What alternative I can use instead of those function?

Can anyone please help me for this?

The answer is in the Date class API. Can you find it ?

It might be helpful to realize that java.util.Date is essentially nothing more than a wrapper for a long value that represents the milliseconds that have passed since January 1st 1970.
Formatting that long value as a human readable String is no longer its responsibility. If you look at the documentation of some of its deprecated methods that used to offer this kind of behaviour (toGMTString() / toLocaleString()), you'll find that DateFormat should indeed be used for this purpose. What's your reason for not wanting to use the DateFormat class?

Edit: Oh, nevermind, I misunderstood your question.

You can use the Calendar class, which is much more flexible than the Date class:

Date date = ...;

// Get Calendar object set to the date and time of the given Date object
Calendar cal = Calendar.getInstance();
cal.setTime(date);

// Set time fields to zero
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

// Put it back in the Date object
date = cal.getTime();
