Student will demonstrate the ability to apply the IS A and HAS A relationships. Program Specifications: Start by watching Video Segment 16 from Dr. Colin Archibald's video series (found in the module overview). Key in the program shown in the video and make sure it works. Then, add the following: Animals have a Weight. Animals have a Height. Dog is an Animal. Dogs have a Name. Dogs have a Breed. Dogs have a DOB. Cat is an Animal Cats have a Name. Cats have 9 lives, so you need to keep track of the remaining lives once a cat dies.

- Note : ALL Code Must be in OOP (JAVA) And perform all in ecplis (console base) Scenario:You are hired by a game development company. Your task is to create an RPG hack & slashconsole game. The game will have a movement system that will be based on the x, y, zcoordinate system. You will need to start with creating 3 classes.1. A class that represents a player2. A class that represents an enemy3. An abstract class that contains the movement logic.Step 1:Start by creating the superclass which defines the movement system for both enemy andplayer. The movement system is based on the Coordinate system. Imagine an x, y, z plane,the y coordinate is used to move forward and backward in the virtual plane, x to go left andright, z to go up and down.For example, A player with coordinates x, y, z with values -5, 10, 0 represents a player -5units to the left, 10 units forward, and 0 z units mean on the ground. (0, 0, 0) are the baseunits which means the player or enemy is at the start of the…python language Write a function that overwrite the greater than method for a class.
