For variables with private access modifier in a class, select all the apply a. b. Cannot be accessed using get methods C. Cannot be directly accessed outside the class d. Can be directly accessed outside the class Can be accessed using get methods

public class Artwork { // TODO: Declare private fields - title, yearCreated // TODO: Declare private field artist of type Artist // TODO: Define default constructor // TODO: Define get methods: getTitle(), getYearCreated() // TODO: Define second constructor to initialize // private fields (title, yearCreated, artist) // TODO: Define printInfo() method // Call the printInfo() method in Artist.java to print an artist's information }} public class ArtworkLabel { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userTitle, userArtistName; int yearCreated, userBirthYear, userDeathYear; userArtistName = scnr.nextLine(); userBirthYear = scnr.nextInt(); scnr.nextLine(); userDeathYear = scnr.nextInt(); scnr.nextLine(); userTitle = scnr.nextLine(); yearCreated =...

Write a C++ program that does the following: Create a class called Automobile This class has the following private attributes: model year mileage This class has the following methods: Default constructor Non-default constructor that will initialize all the above attributes Set/Get method for each of the above attributes displayAuto that will print the information for the Automobile all three attributes on the same line with proper spacing Destructor method that will print a message that the object has been deleted Create a class called Inventory This class has the following private attributes: count: This represents how many current automobiles in the inventory maxCount: This represents the maximum number of automobiles that can be stored autoPtr: A pointer to Automobile objects. This class has the following methods: Default constructor (count is 0, maxCount will be 10, autoPtr is NULL) Non-default constructor that will have one integer parameter count will be initialized...

Define a class named Wall. The class should have two private double variables, one to store the length of the Wall and another to store the height ._Create adefault constructor that sets the length& height to 0, create a second constructor with input parameters for the of the data variables and third copy constructor.Add accessor and mutator functions to read and set both variables Add another function that returns the area of the Wall as double .Write program that tests all your constructors and functions for at least three different Wall objects

Describe how you can use an interface as an alternative to a class to specify the type for a parameter.

in the date classOverload the constructor method as the class diagram showsIn the main program, create three objects of class date, one from each of the constructors.In the main program, overload the showdate method to display the date in the following formatsThe date in dd/mm/yy formatThe date in dd/mm formatThe date in "d of month" formatIn the main program, make use of each of the showdate methods, one with each of the created objects.Send your two files, the date file and the main program where you use the date constructor overload and the showdate method overload.

The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object references

Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design...

True or False Constructors can accept arguments in the same way as other methods.

1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method...

Because of the provision that a single flag can be used as both an ending and a starting flag, a single bit error can cause problems. a. Explain how a single bit error can merge two frames into one. b. Explain how a single bit error can split a single name into two frames.

State whether it is true or false and why .

A cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to...
