- Using the ABCMeta class as the abstract class's metaclass, implement an abstract class inPython. Hint: Create a code snippet.Answer the given question with a proper explanation and step-by-step solution. The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.Let’s build a Player Portfolio System that has an abstract class. Create a new Player Abstract class. Implement getName method in this abstract class. Define other methods as abstract. Here is an example: abstract class PlayerA {private String name;public String getNameA(){return name;}public PlayerA(String name) {this.name = name;}abstract public int getStatsA();abstract public String getSportA();} Create NFL Player and NBA Player concrete classes that will extend Player abstract class. Create a main method to implement your classes

- You are going to declare an abstract class called Player. In the abstract class Player, it should contain common methods found for both Human Player and Al Player. Talk with your team which classes in the Player class should be declared abstract and which ones are supposed to be non-abstract (regular methods). Both Human Player and Al Player should inherit the abstract Player class. Code:Write an abstract class, it can be anything well defined from the very basics.For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass
- What is an abstract class? Choose only one option.(a) An object(b) A class with no methods.(c) A class with no concrete subclasses.(d) A class with at least one undefined message.(e) An interface.Abstract classes and interfaces can both be used to specify common behavior of objects.How do you decide whether to use an interface or an abstract class? Explain youranswer.A subclass of an abstract class must be able to do all of the things the parent class can do. True or not?
