In this question, you will design two classes Flight and Itinerary and write a program to test them. Let's first look at the java.util. GregorianCalendar class which you will use in designing your Flight and Itinerary classes. This class provides the standard calendar system used by most of the world. It has a constructor GregorianCalender (int year, int month, int dayOfMonth, int hour, int minute, int second) which creates a GregorianCalendar object with the given date and time set for the default time zone with the default locale. The month parameter is 0 based, that is, 0 for January. It has a method get TimeInMillis() (inherited from its parent class java.util.Calendar) that returns this Calendar's time in milliseconds (elapsed since midnight, January 1, 1970 GMT) which is in long type. Now let's design the two classes Flight and Itinerary. The Flight class stores the information about a flight with the following members: • A private String data field named flight No for the flight number. • A private GregorianCalendar data field named departureTime. A private GregorianCalendar data field named arrivalTime.

Write the code in java and please dont plagarise or copy from other sources write it on your own and read the question carefully and do what in the question says thank you. 

The ArrayList Class 4. In this question, you will design two classes Flight and Itinerary and write a program to test them. Let's first look at the java.util.GregorianCalendar class which you will use in designing your Flight and Itinerary classes. This class provides the standard calendar system used by most of the world. It has a constructor GregorianCalender (int year, int month, int dayOfMonth, int hour, int minute, int second) which creates a GregorianCalendar object with the given date and time set for the default time zone with the default locale. The month parameter is 0 based, that is, o for January. It has a method get TimeInMillis() (inherited from its parent class java.util.Calendar) that returns this Calendar's time in milliseconds (elapsed since midnight, January 1, 1970 GMT) which is in long type. Now let's design the two classes Flight and Itinerary. The Flight class stores the information about a flight with the following members: • A private String data field named flight No for the flight number. • A private GregorianCalendar data field named departureTime. • A private GregorianCalendar data field named arrivalTime.

Now let's design the two classes Flight and Itinerary. The Flight class stores the information about a flight with the following members: • A private String data field named flight No for the flight number. • A private GregorianCalendar data field named departureTime. • A private GregorianCalendar data field named arrivalTime.
• A constructor that creates a flight with the specified flight number, departure time, and arrival time. • Appropriate getter and setter methods. (Hint: Do we need setter for flight No?) • A method named get Flight Time () that returns the flight time in minutes. Assume the departure Time and arrival Time are in the same time zone. (Hint: Use the method getTime InMillis() to get arrival Time and departureTime in milliseconds, compute their subtraction, and transfer the result from milliseconds to minutes.) The Itinerary class stores the information about itinerary with the following members: • A private ArrayList<Flight> data field named flights that contains the flights for the itinerary in increasing order of departure Time. (Hint: You do not need to do the sorting.) • A constructor that creates an itinerary with the specified flights in ArrayList<Flight> type. • A method named get TotalFlight Time () that returns the total flight time of the itinerary in minutes. (Hint: Invoke the getFlight Time () method for each Flight object.) • A method named get TotalTravelTime () that returns the total travel time in minutes from the departure time of the first flight to the arrival time of the last flight in the itinerary. Assume all the times are in the same time zone. Now write a test program (name the class as TestFlight Itinerary) that has an ArrayList of Flight named flights. Add the following three flights one-by-one to flights: Flight number: "US230" Departure time: 05:05:00 May 5, 2014 (Hint: new GregorianCalendar (2014, 4, 5, 5, 5, 0)) Arrival time: 06:15:00 May 5, 2014 • Flight number: "US235" Departure time: 06:55:00 May 5, 2014 Arrival time: 07:45:00 May 5, 2014 • Flight number: "US237" Departure time: 09:35:00 May 5, 2014 Arrival time: 12:55:00 May 5, 2014 Use flights to create an Itinerary object named itinerary. Print out the total flight time and the total travel time of itinerary.
