How to display difference between two timestamps in Hours

[Hari Kumarkar]

Hi All,
In my application i have two different dates for example
req_date: 2008-12-12 16:54:23
assigned_date: 2008-12-16 19:56:59
Here i want to display the difference between two timestamps in "Hours:minutes:seconds"

Do you have the timestamps as Date objects, or as strings? If they are strings, then first use SimpleDateFormat to parse them into Date objects (see the API documentation of SimpleDateFormat for information on how to do that).

Then, call getTime() on both the Date objects and subtract the return values. This will give you the difference between the two timestamps in milliseconds. With some simple math you can compute how many hours, minutes and seconds that is.

Try writing some code that does what I described above, and if you get stuck, ask more questions here.
