Date Time additions/parsing

[Carla]

Hi,
I have a GUI which has a departure date field (text), departure time
field (text), and once the user enters information about these, I have
to add the estimated time of journey to the departure date-time to
calculate arrival date-time.

Can someone help me, please?

I am getting the date from the departure date field in the following
manner.

String str_date = departdateField.getText();
DateFormat formatter;
Date date;
formatter = new SimpleDateFormat("dd-MMM-yy");
date = (Date) formatter.parse(str_date);
System.out.println("Today is " + date);

Use the Calendar class.

Can you give me a short example to start with? for date-arithmatic I
mean.

Calendar cal = Calendar.getInstance();
cal.setTime(depart);
cal.add(Calendar.MINUTE, journeyHours * 60 + journeyMinutes);

if (destination == Airport.CHICAGO_OHARE)
cal.add(Calendar.MINUTE, 2 * 60 + 30); // congestion
