Select one: O True OFalse Encapsulation is the process of grouping the attributes and method of an object together in a single data structure known as a class Select one: O True O False A constructor is a member variable that is called automatically when an object is created. Select one: O True O False We cannot declare more than one constructor per class. Select one: O True O False onCreate the StockTask1 Java project Create a Stock object class that contains the following information: The symbol of the stock is stored in a private string data field called symbol. The stock's name is stored in a private string data field called name. previousClosingPrice is a private double data area that stores the stock price for the previous day. currentPrice is a private double data area that stores the stock price at the current time. A constructor for creating a stock with the given symbol and name. For the data fields, there are accessor methods (get-methods). For the data fields, there is a mutator method (set-methods). A method named getChangePercent()that returns the percentage changed from previousClosingPrice to currentPrice.

- Write a C# application AutomobileDemo that prompts a user for data for eight Automobile objects. The Automobile class includes the following auto-implemented properties: IdNumber - The ID number (an int) Make - The make (a string) Year - The year (an int) Price - The price (a double) Override the ToString() method to return all the details for an Automobile. During data entry, re-prompt the user if any ID number is a duplicate. Sort the objects in ID number order, and display all their data as well as a total of all their prices. For example if, the output should be in the following format (only two automobiles shown): Automobile 1 2017 honda Price is $30,000.00 Automobile 45 2016 Toyota Price is $20,000.00 Total for all Automobiles is $50,000.00. using System; using static System.Console; using System.Globalization; class AutomobileDemo { static void Main() { // Your code here } }Develop a Visual C# .NET solution that provides a login authentication service. This solution will have a class library component and two application components contained within the same solution. The LoginAuthenticator Class Create a class library project named LibLoginAuthenticator that contains a class named LoginAuthenticator. The LoginAuthenticator class must support the following features: •The class defines a public string read/write property named Username which gets/sets the Username for the authenticator. • The class defines a public string property named Password which sets the Password for the authenticator. The get part should be private. •The constructor for the class should set the initial values of Username and Password to null. • The class defines a public method named Authenticate with no parameters which returns a bool? (nullable bool) value. • If either Username or Password is null, the method should return null to indicate that not all fields were provided. • If…displays the entire anagram.cpp application. To indicate the phrase to be anagrammed, use a class. The class's member methods enable the phrase to be displayed, anagrammed, and rotated. The main() procedure receives a word from the user, constructs a word object with this word as an input, and uses the anagram() member function to anagram the word.
- In an n-sided regular polygon, all sides havethe same length and all angles have the same degree (i.e., the polygon is both equilateraland equiangular). Design a class named RegularPolygon that contains:■■ A private int data field named n that defines the number of sides in the polygon with default value 3. ■■ A private double data field named side that stores the length of the side withdefault value 1.■■ A private double data field named x that defines the x-coordinate of the polygon’scenter with default value 0.■■ A private double data field named y that defines the y-coordinate of the polygon’scenter with default value 0.■■ A no-arg constructor that creates a regular polygon with default values.■■ A constructor that creates a regular polygon with the specified number of sidesand length of side, centered at (0, 0).■■ A constructor that creates a regular polygon with the specified number of sides,length of side, and x- and y-coordinates.■■ The accessor and mutator methods for all data…Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.A class object can encapsulate more than one [answer].

Check ‘n Shop is a grocery supermarket in South Africa that provides a loyalty program to customers on a monthly basis. Customers earn points based on the number of visits and the amount they spend, especially on healthy foods during the month. The private data fields for the Shopper object class are: See attached image The constructor must assign values of the parameters to the private data field variables. The static variable should be incremented by one in the constructor. The increaseLoyaltyPoints() method calculates the number of loyalty points based on the amount a customer spent at the supermarket. All customers receive 100 free points each month. Use the following criteria to calculate the additional points earned to be added to the 100 free points: For every four rands (R4) spent, one loyalty point is awarded. Make use of an appropriate Math class function to round up the loyalty points to a whole number. The updateHealthLevel() method receive the total amount…Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.
