5. class definition for GameEnemy
Next, we want to start making enemies for our upcoming video game, so we will define a class called GameEnemy.
Every GameEnemy will have a name, an x location, a y location, and a number of hit points (which must be a non-
negative integer ). The_init__ method for GameEnemy will take all of these parameters (in that order) and store them
on the object. GameEnemy also needs a method called healthbar, which will allow us to show that enemy's health bar in
the game. It returns the enemy's name followed by a number of asterisks to show how many hit points it has left. The
exact format is shown below.
Sample runs should look like:
>>> enemy = GameEnemy ("TODD", 100, 200, 5)
>>> enemy.healthbar()
TODD: ******
>>> enemy-%
ence
100
>>> enemy-y
200
If vou havo qu octiona
To determine if two objects in a class are equal, we should NOT use "==". We should override the _____ method of the Object class with our own definition of equality.
1. Idenify three objects that might belong to each of the following classes:
a. author
b. raceHorse
c. country
d. retailPurchace

Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full name—the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.arrow_forwardThis is the question - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum.

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.

Create an abstract class Called CD. This class contains the title as String, and playingTime as integer (e.g. 60 minutes). Include a constructor to initialize all the data fields. Create an abstract method called printPlayingTime to show the CD playing details. Make sure all the data fields can be accessed directly from the child classes. Create a class called Album that inherits from the CD and Classical Music. Include a data field called year as integer type. Create a constructor to initialize all the data members. Override the getYear method to return the released year. Override the printPlayingTime method. If the CD title is more than 10 characters, this method will print the first 10 characters, followed by the three ellipse dots and the playing time.

It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230arrow_forwardAssignment:The BankAccount class models an account of a customer.
