Get data between last three years,

Question

I'm try to load data between lasst three years. i want to get data between current datetime and last 3 years back.

eg:-FROM 1/19/2009 TO current time (1/19/2012)

I get the current time as below.

String date= DateFormat.getDateInstance().format(new Date());

Could someone please tell me the way to do this? If you have any worked through examples, that would be a real help!
