        //how to do this?

        // java.util.Date requiredDateDate = feeding requiredDateStr and format

Edit: Question: How to convert this String "10/01/2013 00:00:00" to java.util.Date format?

Ultimately I want to convert this String "10/01/2013 00:00:00" to a java.sql.Date format

It's not clear what you're asking here. You say you want a java.util.Date of a specific format, but java.util.Date isn't in any format at all; it's just a specific instant in time (measured in milliseconds since the epoch) — ComputerDruid, Feb 26 '15 at 17:12
@ComputerDruid you opened my eyes.. Thank you for that information. Yes, I was trying to get a Date of a specific format which is not possible! — spiderman, Feb 26 '15 at 17:41

Use SimpleDateFormat:

SimpleDateFormat df = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss") ;
df.parse("10/01/2013 00:00:00");

See the documentation for more Information about the Format.

For your second question see this thread.

Thanks for the link for my second qn. First one doesn't help me as it gives a Date of some format, where as I was looking for Date of a particular format. For the first one, ComputerDruid well said. If you can append that to your answer, I can accept yours and close this. Thank you for helping me – spiderman Feb 26 '15 at 17:42
@spiderman it gives you the date for the Format you asking for?! – Jens Feb 26 '15 at 17:44
No it doesn't. `java.util.Date` will not. thats what he was explaining – spiderman Feb 26 '15 at 17:49
I was referring to this comment of @ComputerDruid "java.util.Date isn't in any format at all; it's just a specific instant in time (measured in milliseconds since the epoch) " – spiderman Feb 26 '15 at 19:27
@spiderman yes i know. I am not sure what hat this too du with your question? `Question: How to convert this String "10/01/2013 00:00:00" to java.util.Date format?` – Jens Feb 26 '15 at 19:29
Sorry for that, my question title gives more clarity - How to convert this String "10/01/2013 00:00:00" to java.util.Date of the format 'dd/mm/yyyy HH:mm:ss' . If I just do a parse on the dateString, I get a java.util.Date of some format, not exactly in 'dd/mm/yyyy HH:mm:ss' – spiderman Feb 26 '15 at 19:33

convert a String date of format "dd/MM/yyyy HH:mm:ss" to * java.util.Date of format dd/mm/yyyy HH:mm:ss
