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()CLASS NAME List the instance variables in the constructor. List the methods in the class. - indicates private CLASS NAME List the instance variables in the constructor. List the methods in the class. The second row of the UML diagram lists the instance variables in the constructor. For example -name: string o o name is the variable name o string is the data type of name + indicates public o getName is the method name o o string is the return data type Java.util. The third row of the diagram lists the methods in the class. For example, +getName(): string empty parenthesie indicate nothing is sent to the method.
