javatime

How can I calculate a time difference in Java?

I want to subtract two time periods say 16:00:00 from 19:00:00. Is there any Java function for this? The results can be in milliseconds, seconds, or minutes.

Solution 
  • String time1 = "16:00:00";
String time2 = "19:00:00";

SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
Date date1 = format.parse(time1);
Date date2 = format.parse(time2);
long difference = date2.getTime() - date1.getTime();

    Difference is in milliseconds.
