Compate Dates

Question

I want to compare two dates. Say Purchase Date and Manufacturing Date, If the difference between purchase date is more than 100 days from the manufacturing date, it should return true else false.
I tried with creating 2 Date Objects and then comparing with Calendar object, but in any case it returns true.
Please provide a solution.
Thanks.

Here's another way to do it (I've shown all the math ... so check that to make sure I've got it right)
GregorianCalendar cal1 = new GregorianCalendar(2001,12,12); // 12/12/2001
GregorianCalendar cal2 = new GregorianCalendar(2002,5,12); // 5/12/2002
long milli1 = cal1.getTimeInMillis();
long milli2 = cal2.getTimeInMillis();
long secs = (milli2-milli1)/1000; // to seconds
long mins = secs/60; // to minutes
long hours = mins/60; // to hours
long days = hours/24; // to days
System.err.println("Number of days between :"+ days);
