2. Create a program that implements all different kinds inhenitance. Use any object to represent your class and each parent class must have at least 2 constructors (no parameters and 3 paremeters), 3 attributes and 3 methods. Sub class must have an additional attribute and method, and must override at least one of the constructors.

- Age calculation. You must use the object oriented programming for this problem. (1) Create a class called Date that Includes three pieces of information as data members—a month (type int), a day (type int) and a year (type int). Have a constructor with three parameters to initialize the three data members. Call setters inside to initialize each attribute. Provide a set and a get method for each data member. Assume that the values provided for the year and day are correct, but ensure that the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a member function displayDate that displays the month, day and year separated by forward slashes (/). Provide a member function called calculateAge with three parameters that indicate a future date (represented as month, date, and year). Calculate one’s age based on one’s birth date and this future date. Inside the method simply print out one’s age in the format of how many years and how many days. Note that here you are…For this portion of the assignment you will need to create the Employee class * based on the instructions in the API and have implemented the Equals method for that class. * * There is one parameter being passed as to this method that you will use as part of your solution:* An Employee object reference with the identifier testEmployee* * 1) Instantiate an instance of the Employee class using the default constructor and * assign it to an object reference with the identifier defaultEmployee* * 2) Instantiate an instance of the Employee class using the alternate constructor, * passing the following arguments:* name: "Keanu Reeves"* ID: 10010* salary: 78000.00* Assign the instance to an object reference with the identifier keanuEmployee* * 3) Declare a variable of type Employee with the identifier excellentEmployee and assign it * a reference to the same object that is being referenced by the keanuEmployee object reference. * 4) Construct a selection statement that tests if testEmployee is…TECHNICAL REQUIREMENTS 1. The program must utilize at least two classes. a. One class should be for a player (without a main method). This class should then be able to be instantiated for 1 or more players. b. The second class should have a main method that instantiates two players and controls the play of the game, either with its own methods or by instantiating a game class. c. Depending on the game, a separate class for the game may be useful. Then a class to play the game has the main method that instantiates a game object and 2 or more player objects. 2. The game must utilize arrays or ArrayList in some way. 3. There must be a method that displays the menu of turn options. 4. There must be a method that displays a player's statistics. These statistics should be cumulative if more than one game is played in a row. 5. There must be a method that displays the current status of the game. This will vary between games, but should include some statistics as appropriate for during a game.…
- Constructors of a class can be both public and private. Explain why you would create a private constructor. Create a simple class with a single data member of your choice. Create a private constructor. In your code demonstrate how a private constructor is called and how the object is created using a private constructor1. Create a class person having 5 data members. Name Address Cnic Gender Age All data members should be hidden by the use of data hiding concept. These values will be initialize using the child class constructor. For getting the values of these data members getter method will be created for all data members in the parent class i-e Person. 2. Create another class Teacher that will inherit properties and functionalities from perso class. Teacher class will have experience data member and an array of subjects taught that particular teacher. 3. Provide setter and getter methods for all data members. 4. Teacher is allowed to teach at least 2 subjects. 5. Perform input validation in setSubject() function so the user will not be able to input anything except string value. 6. Default experience of the teacher will be 2 years. 7. Parameterized constructor of person clas will be called using the teacher class constructor. This will initialize all the data members of person class. 8. Using…Every attribute and method declared in a class has an access modifier such as private, public and protected. Differentiate each of them.
- You will define three objects class Person, BookAuthor, and Book. Class Person involves a person's identity. Class BookAuthor involves a collection of books or book titles. Class Book involves the number of books in stock , book title and price. Design the three classes: The classes must use an appropriate inheritance relationship. Each class must have a constructor. Each class has at least two private data members and you must include accessors. You must test your classes by creating a BookAuthor object and printing the Person, Book and BookAuthor values from a function you create inside of BookAuthor. Make sure you use the book object correctly and put it inside of BookAuthor. in pytgipls help me using python This is the code it provides: class Artist:# TODO: Define constructor with parameters to initialize instance attributes# (name, birth_year, death_year) # TODO: Define print_info() method. If death_year is -1, only print birth_year class Artwork:# TODO: Define constructor with parameters to initialize instance attributes# (title, year_created, artist) # TODO: Define print_info() method if __name__ == "__main__":user_artist_name = input()user_birth_year = int(input())user_death_year = int(input())user_title = input()user_year_created = int(input()) user_artist = Artist(user_artist_name, user_birth_year, user_death_year) new_artwork = Artwork(user_title, user_year_created, user_artist)new_artwork.print_info()QUESTION 2 Write a class about Aeroplane. Obviously, you will require other helper classes to complement your aeroplane class. Design your classes yourself. The codes should contain the following OOP features implemented in these classes: Class Object Encapsulations accessor/mutator Method overloading Objects as parameters Objects as return type Objects as fields Association Aggression composition Beside your code, comment the name of the feature that is implemented
- 2. Create a class named "Manager". This class has two private attributes: Salary, Address. You want to access those private members from the Main class. You have to create an object of the Manager class then use the setter and getter methods to access those attributes.Design and implement a Restaurant class with at least three meaningful attributes and two methods. Implement a test program which creates at least two instances of the restaurant class and calls all the methods. Some possible attributes are name, numberOfTables, cuisine, numberOfReservations, capacity, etc. Some possible methods are make Reservation, checkAvailability, etc. Note the following: -All properties must be declared as private and you need accessor and mutator methods for each property. - You need to define at least one constructor. Documentation o Include header comments that include description of the program. o Include body comments o Consistent indentations o Consistent white line spaces Properties are declared as private o Accessor and mutator methods are created o At least one default constructor o At least two instances are createdOverloading is when you create another way for the operation to be used like with different data types whereas overriding is like using Inheritance and having the child class have it’s own method. answer choices True False
