The application should be extendable so that a new search criterion can be added, perhaps as a new class, without having to modify the user interface. For example, a client user can add a new criteria by writing a class and registering it with the system. On adding that class, the new criterion should appear as a new item within the combo box.

Simple Student Management System Build the following app using Python Tkinter library. Using this app, user can • add student information • view all students • search student(s) by name • remove student by id Add • First name, last name, date of birth cannot be blank while adding a specific student information. • However major can be blank, which gets set to "Undefined" if left out blank. • Student Id is automatically generated by the program (ex: 1001, 1002, 1003, 1004 ….) If the user keeps a mandatory field blank (ex: First name) and presses "Add Student" button, it displays the following message box: first name is required If the user successfully enters all the necessary information and presses the "Add Student" button, it displays the following confirmation message box: student added View All When the user presses the "View All" button, it displays all the student’s information (Id, First name, Last name, Date of birth, and Major) in a nice formatted way. Example below: • Must…
company wants to make a simple application to keep track of trips andpassengers.you got the following information:3 classes needed one super class Trip and sub classes Passenger and Driver.• It is required to store the whole data in one collection The Trip class has:1- a number2-a driver3-a specific date.4- In addition, passengers could be added or removed within a given limit for the maximum number of passengers who could be in thesame trip.5- there are other attributes (add at least 3 attributes from your choice).6- trip number is unique within the same date. The Driver class has:1- a unique ID2- a name3- other attributes (add at least 2 attributes from your choice). the Passenger class has:1- a unique Civil ID (National ID)2- a name3- other attributes (add at least 2 attributes from your choice but one of them should be common with drivers). Moreover, you have been informed that the following operations happen frequently:• Offering a new trip• Adding a passenger to a specific trip•…
Create a program that uses classes, polymorphism, and enums to monitor blizzards in Europe, with class members including the blizzard name, location, and snowfall amount, with a continuous menu to update, delete, display, search and add data stored in a collection. The application should have a menu that allow users to: • Add a new item to the collection. • Display all the items in the collection. • Search for a specific item. • Exit the application by pressing 0. The application should also display any error messages if the user enters invalid input. Coding Requirements: 1. Demonstrate applied use of foreground color and change in console title 2. Classes created and apply generics, abstract, and polymorphism
previous questions attached on the images, answer required in c++ 1.4.Write a back-end class called AdvancedAPM11A1Encryptor and save it in a file called AdvancedAPM11A1Encryptor.cpp. This class must inherit the functionality of theAPM11A1Encryptor class and add functionality that will enable us to make use of the ExclusiveOR encryption procedure.

You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date date, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email provide getters/setters, constructors, toString. Provide following options to the user. Add Friend (which add new friend to the Friends file) View Friends (read data from Friends file and display) Send message (This should ask for friend name and message match the friend name and write that message to the inbox file). Read messages (This show all messages form inbox on JList or Text area. Note: Create a manager class with methods use to read and write messages to “inbox” file you should write sentMessage(Friend f, Message message) method which write the messages to the file user can send as many message as he/she wants (use loop and arraylist). Write another method readMessages()…

what are the proper steps for this Create a client class named Client with the main( ) method. Inside the main method do the following: Create an instance of BiGBirdcalled Little Squadto store players’ information of U.S Swimm team team using the overload constructor to make the initial length of the list array equal to 2. Add eight players to Little Squad by hardcoding eight calls to the add method (one for each player). Display the contents of Little Squad Remove a random player from Little Squad Display the contents of Little Squad. Get but do not remove a reference to the 3rditem in the bag. Display the contents of the reference you “got” it step 5. Add another Player with another hardcoded add method call. Display the contents of Little Squad. Remove the Player that you “got” in step 5 using a call to the remove(E e)method. Display the contents of Little Squad.

Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.
Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.
