Question

How do I add/subtract two time objects. I have two time objects (arrival and departure) in format of “yyyy/MMM/dd HH:mm:ss”. I need to print the difference between departure and arrival time. I am generating time ad below:

public String getTime() {
    Calendar currentDate = Calendar.getInstance();
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MMM/dd HH:mm:ss");
    return formatter.format(currentDate.getTime());
}

Can I get time in mills and than format it when I needed to print ?

Answer 1

something like this…..

public long getTimeDiff() throws Exception {
    String arrival = "2011/Nov/10 13:15:24";
    String departure = "2011/Jan/10 13:15:24";

    SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MMM/dd HH:mm:ss");

    java.util.Date date1 = formatter.parse(arrival);
    java.util.Date date2 = formatter.parse(departure);

    return date2.getTime() - date1.getTime();
}
