String time; // your string representing the time
SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyyMMddHHmmss");
Date startDate = dateFormatter.parse(time);

and

new Date() 

will give you a date representing the current date and time.

When comparing dates, once you have the date object as shown by kett_chup, use date.getTime() which gives you the milliseconds and you can then easily compare with another date.getTime() to determine if one date came before or after the other.
