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. This class must have the following structure: Inherited Data Members Data Type: intName: int key Description: This member will store the key that will be used during the encryption process Public Methods Return Type:charMethod Signature : encryptACharacter(char character) Description:This method must encrypt the received character by using the key class member and the ExclusiveOR encryption technique. Inherited Methods Method Signature:encryptPage(Page page), setKey(int key 1.5. Write a main program and save it in a file called Run.cpp. In this program you must read a text file that contains sentences into a Page object, encrypt the…
Is there a different way of doing this problem? Question: Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Test your class by writing a main function that creates five access…
Please complete the following tasks: Write a class “Actor” that contains two attributes with the appropriate level of visibility explicitly defined. “Name” which is a String, Private, “NumberofAwards” which is an integer, private Write a default Constructor for this class that initializes the name to “Bob Smith” , and the number of awards to 0. Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.

User: Make a class called User. Create two attributes called first_name and last_name, and then create several other attributes that are typically stored in a user profile. Makea method called describe_user() that prints a summary of the user's information. Make another method called greet_user() that prints a personalized greeting to the user.Then - Create several instances representing different users, and call both methods for each user. Admin: write a class called Admin that inherits from the User class. Add an attribute,privileges, that stores a list of strings like "can add post”, "can delete post”, "can banuser”, and so on. Write a method called show_privileges() that lists the administrator'sset of privileges. Then - Create an instance of Admin, and call your method.

a- Prepare a MS. Word document that contain a UML represent a class ofyour choice, the class should satisfy the following properties:- Consists at least three private attributes.- Two constructors one with no arguments and one with arguments.- Getter and setter methods for all attributes.- Override the equals method.- implement the Comparable interface.- Override the toString methods to return a string which representsall object’s information.b- Implement the above class using java and NetBeans IDE.c- Create class called Test with main method to do the following:- Create ArrayList object.- Create the 4 objects of the above class, the information should readfrom input console.- Add the objects in the ArrayList object.- Display the information of all objects in the array list. I want different class than before

(1) Create two files: Car.java - Class definition, object class CarTester.java - Driver program, contains main() method Build the Car class with the following specifications: Private fields:String make - Initialized in default constructor to "none"int mileage - Initialized in default constructor to 0 Constructors:Default constructor with no parameter Overloaded constructor with two parameters Methods:setMake() & getMake() setMileage() & getMileage() (2) In your testing class, prompt the user for information to create two car objects of the Car class. Remember that the car make could contain multiple words, such as "Land Rover". Think about which method you should use in order to read in the car make information (nextLine() or next()?).A possible problem: you might notice that your nextLine() method does not read in anything when it is called after next() or nextInt() method. To fix this, you need to call an empty scan.nextLine(); to be able to read in the user's…
(1) Create two files to submit: ItemToPurchase.java - Class definition ShoppingCartPrinter.java - Contains main() method Build the ItemToPurchase class with the following specifications: Private fields String itemName - Initialized in default constructor to "none" int itemPrice - Initialized in default constructor to 0 int itemQuantity - Initialized in default constructor to 0 Default constructor Public member methods (mutators & accessors) setName() & getName() setPrice() & getPrice() setQuantity() & getQuantity() (2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call scnr.nextLine(); to allow the user to input a new string.
