Question

I was looking thru java Date libraries
1. java.util.Date,
2. Date4J
3. Joda-time

to find out whether I can perform time subtraction to two Date Objects, to the precision of milliseconds.

I receive 2011-05-29T22:50:12.692 as a String, and convert it into a Date object by parsing it with SimpleDateFormat.

The other Date object will also be received a String. and I want to subtract from two Date objects.

Any ideas?

Basically i want to get an interval between the two Date objects, to the precision of milliseconds.

Answer 1

Try using Date.getTime()

long timeBetweenInMillis = d2.getTime() - d1.getTime();

EDIT

This assumes that d2 is chronologically after d1.
