JAVA

Create an Itinerary class. This class will represent a travel itinerary containing one or two flights in our system. It should contain two constructors, two instance variables (two different Flights) and seven methods (getFirstFlight, getSecondFlight, hasConnection, getTotalCost, getDeparture, getArrival, toString) [15 points]

overloaded constructor: will take one Flight object and use it to set up the instance variables. The second Flight variable should be set to null.

overloaded constructor: will take two Flight objects and use them to set up the instance variables.

getFirstFlight(): returns the first Flight in the itinerary.

getSecondFlight(): returns the second Flight in the itinerary.

hasConnection(): returns true if the itinerary contains two Flight objects.

getTotalCost(): returns the total cost of all Flights in the itinerary.

getDeparture(): returns the departure time of the first flight in the itinerary.

getArrival(): returns the arrival time of the last flight in the itinerary.

toString(): will return the total cost of the itinerary and the “detailed string” for the Flight or Flights in the itinerary.

Create a FlightManager class. This class will store instances of the Flight class, and support generating a list of potential itineraries. It should contain one constructor, two instance variables (an array of Flights, and something that counts the number of flights in the system), and four methods (addFlight, increaseSize, findItineraries, shrinkItineraries). [25 points]

default constructor: will set up the instances variables with zero flights.

addFlight(…): Adds a flight to the flights array. Uses the increaseSize() method if the array is full.

increaseSize(): Doubles the size of the flights array, while keeping whatever is already there. Make this a private method.

findItineraries(…): Searches the flights based on source airport, destination airport, and departure time, to find 1-flight and 2-flight itineraries meeting those criteria. When searching for 2-flight itineraries, checks that the flights have a connecting city, and that the first arrives in time for the second. Your method should create an array of potential itineraries that can be returned.  (If it helps, you may assume that this method will never find more than 100 itineraries.) Use the shrinkItineraries() method to “clean up” up the potential itineraries array; see below. Hint: use loops to search for all the flights in the flights variable, check if they meet the criteria, and then create a new Itinerary object if the criteria is met.

shrinkItineraries(…). Takes an array of itineraries, where some of the later indices are unused (null), and returns a new array of itineraries where there are no empty indices. Make this a private method.

   java programmingT1. Write a program that models checkout lines at a supermarket; you have to use one of the data

structures being covered in the lectures and explain why your choice of the data structure is well

justified. Several lines of customers should be displayed. You can add a new customer by pressing a

key. You’ll need to determine how the customer will decide which line to join. The checkers will

take random amounts of time to process each customer (presumably depending on how many

groceries the customer has.) Once checked out, the customer is removed from the line. For

simplicity, you may simulate the passing of time by pressing a key. Perhaps every key-press

indicates the passage of one minute. (Java may have more sophisticated ways to handle time.)

• Submit the source code that you have created to complete the assignment, but not the existing

library code (e.g., library code related to data structures and associated algorithms); specify the

origin of the library code you used (e.g., the textbook website) in the report

The report should also contain the text that explains and discusses your work:

1. It should be easily comprehensible to anyone who has taken a module on Data Structures

and Algorithms.

2. One of the main purposes is to convincingly demonstrate that you understand what you are

presenting.

3. It should be self-contained as much as possible and, thus, should contain the key code

fragments rather than merely referring to the submitted full source code.

4. Discuss any (potential) limitations or weakness of your work and how you would improve

if you have more time. Discussing the weakness would not negatively count towards your

mark. It is a recommended practice
