  3. Travel Agents System Java Program

    Travel Agents System Java Program

    Travel Agents System Java Program


    You are to develop program in Java for a small travel agents. The company arranges holidays from four UK airports to five international destinations. Users need to find flight times and costs for journeys between these destinations. The system also provides information on hotels at the destinations (name of hotel and cost per person per night). Information on hotels can only be added, or loaded from file, when the program is running. The following table (Table 1) provides the airport names, destinations, costs and flight times for the journeys Table 1 Information for the travel agents program – the two values represent cost (£) and flight time (hours) respectively – you can make up your own (realistic values) if you wish


    Airport/Destination | New York |Dahab | Rome |Sydney |Tokyo
    East Midlands |200/5.0 |150/4.0 |100/1.0 |500/22.0 |400/12.0
    Birmingham |190/4.8 |140/3.5 |95/1.1 |480/22.5 |380/12.5
    Heathrow |195/4.9 |140/3.6 |95/1.1 |490/23.0 |390/12.5
    Manchester |210/5.5 |145/3.7 |110/1.2 |470/22.7 |370/12.6


    (the above is a data table, where there is a line, represents the cell)


    Your program should have a main menu with four options – Time, Price, Hotels and End (which terminates the program). The Hotels option takes the user to another (Hotel) menu with the following six options – View Hotels; Add Hotel; Delete Hotel; Save Hotels; Retrieve Hotels; Exit (back to the previous menu). Note that your program should include appropriate error trapping – for example, entering an invalid date (eg 30 February).
    Functionality for each of these menu options is explained below:
    Time – Provides the flight time presented in hours.
    Price – The cost of travelling from an airport to a given destination (both selected by the user). Note, if the customer is travelling on the last day of the month the fare should be increased by 5% (and display a message to say that this has been done). The system will therefore need to ask the user the date of travel. It should not simply ask the user if it is the end of the month – but work this out from a date provided by the user.
    Hotels – Takes the user to a Hotels Information Menu.
    Hotels menu
    View Hotels – The user selects a destination and the system displays all available hotels at that destination including the overnight cost per person. If there are no hotels for a destination it should display a message to say so.
    Add Hotel – Allows the user to add a hotel for a given destination. This should add to the list of existing hotels for that destination (if there are any). For example, I might add 'Belle Vue' as a hotel in Sydney at a cost of £50 per person per night.
    Delete Hotel – Allows the user to delete a hotel from a list of hotels at a destination.
    Save Hotels – save all the information on all hotels to a single file in a format of your choosing.
    Retrieve Hotels – read in all the information on hotels from a user selected file (a file saved using the previous option). This should overwrite any existing hotel data in the program when it is running.


    Marking
    The more functionality you add to the program the higher your mark. Begin by getting the menu options in place then add functionality to your program in the following order (make sure that earlier parts of the system are working properly before moving on). Your program should also be structured in an object oriented way. You should try to identify and implement a number of classes for this program.


    Minimum pass (40%)
    The flight time between any airport and destination;
    The cost of travel between any airport and destination;
    Increased cost of travel on the last day of the month and a message to say this has been applied;


    40%-70%
    View hotels – users can view information on all hotels at a chosen destination; Add hotel – the ability for users to add hotels for a destination;
    Sort hotels – users can sort all hotels alphabetically;


    Documentation
    Your coursework should be submitted with appropriate documentation. You should include class diagrams, designs, functionality not completed, functionality working, test plans, evaluation, and program listings. Make sure you include an explanation of how your code should be run (eg. which file should be compiled and run and anything I need to know about using the program – a user guide).

    Special Price: $12.00

    Tracking Contributors Linked List Java Program


    Your first task in developing the application for tracking contributors is to load a list of the people who are helping the cause. Design and develop a linked list, implemented as a stack, to track all of the contributors. You will read the contributor information from a file provided; it is a comma delimited (CSV) file. Your design should include the following:


    Each contributor will have the following Information:
    • Name: String; //the name of the contributor
    • City: String; //the city in which the contributor lives
    • Country: String; //the country in which the contributor lives
    • Phone: String; //the phone number for the contributor
    • Contribution: Double; //the amount of the contribution given by the contributor to the zoo
    • ID: Integer; //identifier key for future needs


    Contributor Functions/Methods:
    • Input constructor: //to accept a string for the name and additional information for each contributor (this should call the Push constructor to implement the stack)
    • Print constructor: //to print out the contributor data
    • Pop constructor
    • Push constructor


    Deliverables:
    • A fully documented program to load the data implemented as a stack
    • A test plan to show how the program runs and can be executed
    • A screenshot showing that the program loaded the data, and after all data is loaded, perform a single pop of the stack

    Exercise 6.16 (Multiples) Write a method isMultiple that determines, for a pair of integers, whether the second integer is a multiple of the first. The method should take 2 integer arguments and return true if the second is a multiple of the first and false otherwise.[Hint: Use the remainder operator]. Incorporate this method into an application that inputs a series of pairs of integers (1 pair at a time) and determines whether the second value in each pair is a multiple of the first.


    Exercise 6.20 (Circle Area) Write an application that prompts the user for the radius of a circle and uses a method called circleArea to calculate the area of the circle.


    Exercise 6.35 (Computer-Assisted Instruction) The use of computers in education is referred to as computer assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use a Random object to produce 2 positive 1-digit integers. The program should then prompt the user with a question, such as "How much is 6 times 7?"


    The student then inputs the answer. Next, the program checks the student’s answer. If it's correct, display the message "Very Good!" and ask another multiple question. If the answer is wrong, display the message "No. Please try again." And let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question correctly.

    Exercise 7.14 (Variable-Length Argument List) Write an application that calculates the product of a series of integers that are passed to method product using a variable-length argument list. Test your method with several calls, each with a different number of arguments.

    Exercise 7.19 (Airline Reservations System) A small airline has just purchased a computer for its new automated reservations system. You've been asked to develop the new system. You're to write an application to assign seats on each flight of the airline's only plane (capacity: 10 seats).
    Your application should display the following alternatives: "Please type 1 for First Class" and "Please type 2 for Economy." If the user types 1, your application should assign a seat in the first class section (seats 1–5). If the user types 2, your application should assign a seat in the economy section (seats 6–10). You application should then display a boarding pass indicating the person's seat number and whether it's in the firstclass or economy section of the plane.
    Use a 1 dimensional array of primitive type Boolean to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available.
    Your application should never assign a seat that has already been assigned. When the economy section is full, your application should ask the person if it's acceptable to be placed in the first class section (and vice versa). If yes, make the appropriate seat assignments. If no, display the message "Next flight leaves in 3 hours."

    Exercise 8.4 (Rectangle Class) Create a class Rectangle with attributes length and width, each of which defaults to 1. Provide methods that calculate the rectangle's perimeter and area. It has set and get methods for both length and width. The set methods should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class Rectangle.

    Exercise 11.9 (Order of catch Blocks) Write a program that shows that the order of catch blocks is important. If you try to catch a superclass exception type before a subclass type, the compiler should generate errors.


    Exercise 11.17 (Catching Exceptions with Superclasses) Use inheritance to create an exception superclass (called ExceptionA) and exception subclasses ExceptionB and ExceptionC, where ExceptionB inherits from ExceptionA and ExceptionC inherits from ExceptionB. Write a program to demonstrate that the catch block for type A ExceptionA catches exceptions of types ExceptionB and Exception C.


    Exercise 11.18 (Catching Exceptions Using Class Exception) Write a program that demonstrates how various exceptions are caught with Catch
    (Exception exception).
    This time define classes ExceptionA (which inherits from class Exception) and ExceptionB (which inherits from class ExceptionA). In your program, create try blocks that throw exceptions of types ExeptionA, ExceptionB, NullPointerException and IO Exception. All exceptions should be caught with catch blocks specifying type Exception.

    CIS355A Week 4 Course Project Flooring Application Analysis and Design


    Developing a graphical user interface in programming is paramount to being successful in the business industry. This project incorporates GUI techniques with other tools that you have learned about in this class.
    Here is your assignment: You work for a flooring company. They have asked you to be a part of their team because they need a computer programmer, analyst, and designer to aid them in tracking customer orders. Your skills will be needed in creating a GUI program that calculates the flooring cost and stores the order in the database.
    The project has three components: an analysis and design document, the project code, and a user manual. The analysis and design document is due Week 4. The code and user manual are due in Week 7. It is suggested that you begin working on the code in Week 5, which should give you ample time to complete the project. You will find that the lectures and lab assignments will prepare you for the Course Project.


    Guidelines
    Your application must include at least three tabs. The user will choose wood flooring or carpet, enter the length and width of the floor, as well as the customer name and address. The application will compute the area of the floor and the cost of the flooring considering that wood floor is $20 per square foot and carpet is $10 per square foot. A summary should be displayed, either in a tab or another window, listing the customer name and address, floor selection, area, and cost. This information should also be stored in the MySQL database table. The program should validate that all information is entered and that the length and width are numeric values. Any numeric or currency values must be formatted appropriately when output. Recommendations for the components used for input are
    • radio buttons—flooring type (wood or carpet);
    • text fields—customer name, customer address, floor length, and floor width; and
    • buttons—calculate area, calculate cost, submit order, display order summary, display order list.
    The MySQL database table is called flooring and has the following description.
    Field Type
    CustomerName varchar(30)
    CustomerAddress varchar(50)
    FlooringType varchar(10)
    FloorArea Double
    FloorCost Double
    In addition to entering new customer orders, your application should list all customer orders stored in the database. These will be viewed as a list, in a text area, and will not be updated by the user.


    Analysis and Design (Due Week 4)
    In Week 4, you will complete the analysis and design for the project. You will use the guidelines described above and the grading rubric below to complete this document. You will create the following items.
    1. Request for new application
    2. Problem analysis
    3. List and description of the requirements
    4. Interface storyboard or drawing
    5. Design flowchart or pseudocode
    The analysis and design document will be a single MS Word document, which contains all descriptions and drawings. See the grading rubric below for the analysis and design document, due in Week 4.
    Item Points Description
    Request for New Application 2.5 A table containing: date of the request, name of the requester (your professor), the purpose of the request, the title of the application (create your own title), and brief description of the algorithms used in the application
