- Encapsulation is a form of information hiding and an important characteristic of object-oriented programming. When a programmer accesses a property that has been encapsulated, he/she has no way of knowing how that property is implemented. All he/she knows is how to access that property via the public setter and getter methods. What are some examples of encapsulation or information hiding in the Bible? Give 1 or more examples and explain how they qualify as encapsulation or information hiding. Must be 300-350 words. Current APA formatting is required for any citations. At least 1 scholarly citation must be included.Describe the classes, methods and attributes that you would use in the Object Oriented design of a simulated automobile. Use this format to describe your classes: Class: Door Methods: void Open(), void Close(), void SetLock(bool), bool GetLocked(), etc. Attributes: bool open, bool locked, class Window, etc.Consider an online holiday booking system.

You should design and develop a class that will be used to create objects that hold information about flights. The information kept about each flight includes: ● Flight number • Departure time • Seat capacity Seats sold Flight destination Flight departure point (i.e. Dublin, Cork, etc.) When creating a flight object the flight number, departure time, seat capacity, flight destination and departure point are given. Behaviour Functions of this class: • Default Constructor - initialises all data members. Constructor that takes the flight no as input parameter and request user input, departure time, seat capacity, flight destination, flight departure point, flight time. ● • A check_available_seats function that returns the number of unsold (still available) seats on a flight; • A sellseats function that takes as a parameter the number of seats a customer requires on a flight.

- 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 referencesPick an object around you and create a class out of it - plan your class (Name, Parameters, Functionality) - your object has to have at least 4 parameters ( 2 string, 2 numbers) - your data has to be private - implement (override) the function __str__ to show the relative information for your function - create at least one extra function in your class for the object - create 4 different objects from your design class This question is based on python.Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…
- E1. Please implement the Abstraction-Occurrence design pattern according to the class diagram shown below. Demonstrate the classes by writing a program that uses TVSeries and Episode objects. TVSeries Episode seriesName * number producer title storySynopsisPYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciatedObject Oriented Programming: 213COMP, 214COMP (Feb-2022) Assignment- I [10 marks] Academic honesty: O Only pdf file accepted & student ID, will be your upload file.
