Use object-oriented features of Java for a Quiz program. Include  class variables, instance variables, inheritance, polymorphism, abstract classes, "this", "super", interfaces, and event listeners

Abstract classes and interfaces may both be used to accomplish the goal of defining the behavior of common objects.Which factors should you take into account when deciding whether to utilize an interface or an abstract class?

pls 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()

Java program: The class diagram with four classes Mammal, Human, Student and Doctor is given. The Mammal class is given as well. Write down the remaining classes as described in the class diagram. The fields and methods for each class is given in the attachment. //in Mammel.java Public interface Mammal{ public double hairColor(): }   1. Class Human: Fields: age(int), weight(double), height(double) Methods: getAge, getWeight, getHeight 2. Class Student: Fields: major (String), gpa (double), creditHours (int) methods: getMajor: returns major, getGpa: returns gpa, getYear: returns freshman, sophmore, junior, senior as determined by earned credit hours Freshman : less than 32 credit hours sophmore: at least 32 but less than 64 credit hours junior: at least 64 credit hours but less than 96 credit hours senior: at least 96 credit hours 3.Class Doctor: Fields: years(int), Speciality (String) methods: getYears: returns years, getSpeciality: returns speciality, getSalary: calculates…

Object-Oriented Programming (Please do not use AI) Create a Java program that has the following: Inheritance -  Create a superclass and one or more subclasses that inherit properties and methods from the superclass.  Polymorphism - Show polymorphism by using method overriding and method overloading.  Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation -  Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction.  Show examples of the following  words: super, this, static, final

Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?

When should one use an abstract class, when should one use an interface, and when should one use both?

6.b.Fast in java coding please. Thank you 1. Abstract classes and interfaces can both be used to model common features.How do you decide whether to use an interface or a class?2. What is Garbage Collection and how can you mark an object for GarbageCollection.

In the class diagram below we have a parking charge class for an object-oriented parking system that is to be designed using java. Briefly explain any implementation decisions and the reasoning behind those without writing the complete code. N.B explain how the implementation will proceed instead of writing code

Explain and give: Interface using examples. why you mighti use an Abstract class rather than an reasons
