How do you convert a String in yyyyMMddHHmmss format to a Calendar value so it can be edited?

I've been looking at the SimpleDateFormat, the Calendar and the Date APIs and haven't been able to figure out how to do it

What is the format I use for formatting the String to whatever it is that Calendar can read?

So, I have temp, which grabs the attribute data from an XML file, and I'm trying to convert it to a Date so it can be converted into a Calendar (I'm not sure if this is the correct approach):

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyyMMddHHmmss");
SimpleDateFormat timeFormatStored = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String temp = frontSplitString((attr.getValue(i).toString()).trim());
java.util.Date date1 = null;
try {
     date1 = inputFormat.parse(temp);
} catch (ParseException e) {
Calendar startthis = date1.getDate();
However, I get an error when I try this saything that I cannot convert from int to Calendar.

I've also tried:
Calendar startthis = timeFormatStored.format(date1).getDate();
But I get this error: The method getDate() is undefined for the type String

And also:
Calendar startthis = timeFormatStored.parse(temp);
Error: Cannot cast from Date to Calendar

Calendar startthis = Timestamp.valueOf(temp);
That doesn't work either.
Error: Type mismatch: cannot convert from Timestamp to Calendar

Where does the problem lay? Or, what am I missing? What is the code that makes it work?
