(The MyDate class) Design a class named MyDate. The class contains: The data fields year, month, and day that represent a date. month is 0-based, i.e., 0 is for January. A no-arg constructor that creates a MyDate object for the current date. A constructor that constructs a MyDate object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. A constructor that constructs a MyDate object with the specified year, month, and day. Three getter methods for the data fields year, month, and day, respectively. A method named setDate(long elapsedTime) that sets a new date for the object using the elapsed time. Draw the UML diagram for the class and then implement the class. Write a test program that creates two MyDate objects (using new MyDate() and new MyDate(34355555133101L)) and displays their year, month, and day. (Hint: The first two constructors will extract the year, month, and day from the elapsed time. For example, if the elapsed time is 561555550000 milliseconds, the year is 1987, the month is 9, and the

Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result
1. (The Fan class) Design a class named Fan to represent a fan. The class contains: The Fan class Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. A private int data field named speed that specifies the speed of the fan (the default is SLOW). A private boolean data field named on that specifies whether the fan is on (the default is false). A private double data field named radius that specifies the radius of the fan (the default is 5). A string data field named color that specifies the color of the fan (the default is blue). Accessor and mutator methods for all four data fields. A no-arg Constructor that creates a default Fan. A method named toString() that returns a string description for the fan.
(The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Use the MyDate class defined in Programming Exercise 10.14 – see the textbook - to create an object for date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person's name. Draw the UML diagram for the classes and implement them. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.

Now, create a function in each of these classes which prints"I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well asMarine Animals" respectively. Now, create an object for each of the above class and try callingfunction of Mammals by the object of Mammalfunction of BlueWhale by the object of BlueWhalefunction of each of its parent by the object of BlueWhalefunction of MarineAnimal by the object of MarineAnimal in c++?

(TicTacToe Class) Create a class TicTacToe that will enable you to write a complete programto play the game of tic-tac-toe. The class contains as private data a 3-by-3 two-dimensional arrayof integers. The constructor should initialize the empty board to all zeros. Allow two human players.Wherever the first player moves, place a 1 in the specified square. Place a 2 wherever the second player moves. Each move must be to an empty square. After each move, determine whether the gamehas been won or is a draw. If you feel ambitious, modify your program so that the computer makesthe moves for one of the players. Also, allow the player to specify whether he or she wants to go firstor second. If you feel exceptionally ambitious, develop a program that will play three-dimensionaltic-tac-toe on a 4-by-4-by-4 board. [Caution: This is an extremely challenging project that couldtake many weeks of effort!]

(Triangle class) Design a new Triangle class that extends the abstract Geometricobject class. Draw the UML diagram for the classes Triangle and Geometricobject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filed. The program should create a Tri- angle object with the se sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
