Add 14 Days to inputted Date

I have a string that gets inputted then printed on the console as a date int the MM/dd/yyyy format. I would like to add another date which would be an approximate ship date. So I need to add 14 days to the order date. I'm not real sure where to start, I have found problems with the month and year changing if the days are to much for the given month. Any help would be appreciated. Thanks
String orderDate;

	

	scanner.useDelimiter(System.getProperty("line.separator"));

				

	System.out.print("Enter the date of order(e.g 11/01/2007):");

	orderDate = scanner.next();

	

	String strFormat = "MM/dd/yyyy";

	String strDate = orderDate;

	DateFormat myDateFormat = new SimpleDateFormat(strFormat);

	Date myDate = null;

	try {

	     myDate = myDateFormat.parse(strDate);

	} catch (Exception e) {

	     System.out.println("Invalid Date ");

	     e.printStackTrace();
 

	}

	

	if (myDate != null) {

	

		String DATE_FORMAT = "MMMM dd, yyyy"; 

		java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(DATE_FORMAT);

		String currentTime = sdf.format(myDate);

System.out.println("         Date Ordered:            "+currentTime);}}}

Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.DATE, 14);
date = cal.getTime();

I know this is going to sound crazy but where would I place this code? And would this give me an additional date from the one I got above? The one above displays the date ordered on the console and I also need to show a shipped date which would be the second date on the console. thanks

Here is the code you require.
Just insert it after you have parsed the date into myDate (after line 13 in your code)
import java.util.Calendar;
 
 
 
 

Calendar calendar = Calendar.getInstance();

calendar.setTime(myDate);

calendar.add(Calendar.DATE, 14);

myDate = calendar.getTime(); // this will be current + 14

put it where you want to calc the new date

      Date shippedDate = null;
      if (myDate != null) {

         Calendar cal = Calendar.getInstance();
         cal.setTime(myDate);
         cal.add(Calendar.DATE, 14);
         shippedDate = cal.getTime();

use the same code you use to format other date

                DateFormat mmddyyyy = new SimpleDateFormat("MM/dd/yyyy");
                String shippedTime = mmddyyyy.format(shippedDate);
