- PYTHON: 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 appreciatedIn this exercise, you are going to be working with 4 classes, a Book superclass with TextBook and Novel subclasses, and a BookTester class to run your program. For the Book, TextBook, and Novel class, you will create a constructor and all getters and setters. Be sure to follow standard naming conventions for your getters and setters! Additional information for each class is below. Book Class The Book class will have a title and author as instance variables and the constructor should follow this format: public Book(String title, String author) TextBook Class The TextBook class will have a subject and edition as instance variables and the constructor should follow this format: public TextBook(String title, String author, String subject, String edition) Novel Class The Novel class will have a genre and pages as instance variables and the constructor should follow this format: public Novel(String title, String author, String genre, int pages) BookTester In the tester class, you should…Finish the TestPlane class that contains a main method that instantiates at least two Planes.

- java You are part of a team writing classes for the different game objects in a video game. In this assessment you are given a superclass (Human.java), two subclasses (Warrior.java and Wizard.java) and a test application (TestGameObjects.java). Both the Warrior and the Wizard classes need to be able to calculate stealth. This needs to be done in the method getStealth. This method has an integer parameter (dexterity) and returns an integer. Refer to the test application to see how the method is used. The Warrior and Wizard classes calculate stealth differently: The Warrior's stealth is equal to dexterity times strength (dexterity * strength) while the Wizard's stealth is equal to three times dexterity times intelligence (3 * dexterity * intelligence). You need to write an interface with the method getStealth, and then modify the superclass and subclasses to implement this interface. You also need to test the validity of the object ID. The object ID must consist of the character 'W'…This is the question I am stuck on - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains the following fields: sampleNumber - of type int description - A description of the type of rock (of type String) weight - The weight of the rock in grams (of type double) Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor. This is what I am given - import java.util.*; public class DemoRocks { public static void main(String[] args) {…In Java Language Create a CheckingAccount class to represent a checking account This class inherits from the Account class that you've created so far and has one new attribute, the overdraft limit, specifying how much the account can be overdrawn by. For example, if you have $100 in the account and you try to withdraw $150. This would be fine, if your overdraft limit was $50, meaning you can overdraw your account by $50 without penalty. Note: All you're doing at this stage is creating the limit, don't worry about dealing with the overdraft yet. You just want a variable at this stage. Your CheckingAccount class should also have getters and setters for the overdraft attribute and a constructor, but keep in mind how constructors work with inheritance. No other methods or adjustments are to be made at this time. Write a driver (or use your existing one) to test your CheckingAccount class by creating at least 1 instance and printing out its overdraft limit by using the getter.
