How to compare two dates along with time in java

Question

I have two Date objects with the below format.

SimpleDateFormat sdf = new SimpleDateFormat(\"yyyy-MM-dd\'T\'HH:mm:ss\");
String         


        

Answer 1

Since Date implements Comparable, it is as easy as:

date1.compareTo(date2);

As the Comparable contract stipulates, it will return a negative integer/zero/positive integer if date1 is considered less than/the same as/greater than date2 respectively (ie, before/same/after in this case).

Note that Date has also .after() and .before() methods which will return booleans instead.
