You have to obtain the to dates in Date instances. From there you get two milliseconds using Date.getTime. After that obtain the difference in milliseconds and with the difference create a new Date. Using SimpleDateFormat you cand print the difference.
So, as a rule of thumb, obtain milliseconds and do calculations in milliseconds. Don't parse or use Strings, is too complicated.
