@madhu: You should be able to use that answer together with the Java docs to easily fix your problem as well. Did you try anything at all? — Keppil, Jan 10 '14 at 10:58

Check this out:

    try {
        SimpleDateFormat format1 = new SimpleDateFormat("MMM dd, yyyy");
        SimpleDateFormat format2 = new SimpleDateFormat("yyyy-MM-dd");
        String stringDate = "Dec 13, 2013";

        Date date = format1.parse(stringDate);

        System.out.println(format2.format(date));
    } catch (ParseException exp) {
        // Take appropriate action
    }

Output: 2013-12-13

You need to enclose `format1.parse(stringDate)` inside try catch block otherwise it will give you ParseException. – Qadir Hussain Jan 10 '14 at 11:03
@Qadir: Thats true. I have modified the post. – Ankur Shanbhag Jan 10 '14 at 11:08

Use SimpleDateFormat as here: new_date is your Date

String stringDate = "Dec 13, 2013";
SimpleDateFormat format = new SimpleDateFormat("YYYY-MM-DD"); 
Date new_date=format.parse(stringDate);

In programming a very important skill is taking information that is close to what you need and using it to find what you do need.

Look at the link in the comments and you can see:

http://download.oracle.com/javase/1.5.0/docs/api/java/text/SimpleDateFormat.html

Read that and you have what you need to adjust the answer there to give the results you want.

I would do something like:

SimpleDateFormat parser = new SimpleDateFormat("MMM dd, yyyy");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date reportDate = parser.parse(stringDate)
String result = formatter.format(reportDate);

String date="Your date";
SimpleDateFormat format = new SimpleDateFormat("MMM DD, YYYY"); 
Date d= format.parse(date);
DateFormat newFormat = new SimpleDateFormat("YYYY-MM-DD");
System.out.println(newFormat.format(d));
