Answer 1

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

Answer 2

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:

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

Answer 3

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);

Answer 4

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));

Answer 5

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);
