- java programming language You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is tested – create…Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Java Programming Create your own class that illustrates the use of encapsulation. Make sure to include at least one setter and one getter for the class
- Java Programming: ConWay World Conway’s game of life is a simple simulation of life forms in a two dimensional grid. The ConwayCell implements the standard behavior of a call in Conway’s Game of Life. You only need to implement and test two new classes. You will create two different cells, derived from AbstractCell. 1. Alternating Cell The first class that you should create is a class named AlternatingCell. This is a cell that should alternate between being alive and dead with each generation. Add one or more of your AlternatingCells to your ConwayWorld. You can see how to add a cell in line 15 - 20 of Main.java. Give your AlternatingCell a unique display character when it is alive so that you can see it in your conway world. 2. Your own cell For the second cell you should feel free to implement any behavior that you want. If you are having trouble thinking of ideas then post up a question. You can add your custom cell in just a few places in the world, or you might choose to replace…Language is Java Write a Clothing class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "Doctor Who hoodie", "slacks") price (e.g., 19.99, 7) Include only one constructor. 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 Clothing 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 Clothing object whose color was blue, whose display name was work trousers, for a price of 27.99, you could use the getters to print something like this:These work trousers are blue and cost $27.99.Don't hardcode the print statement for full credit, you must use the gettersJAVA Task Write a JAVA class named Account to represent an account that you may find at a bank. Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these. Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to. Include a constructor with parameters used to assign values to both attributes. Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below. withdraw method This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount. deposit method This method simulates depositing money into…

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. Bird is an Animal Birds have a wing span Birds have a canFly which is true or false (some birds cannot fly) Create a test class that creates one of each type of animal and displays the animal’s toString method. Submission Requirements: You must follow the rules from the prior assignments. UMLs and Design Tools are not required for this one. YOU MAY…Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
- public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.Search for textbooks, step-by-step expl = bartleby e Q&A Library Design a class nam Start your trial Design a class named MyPoint to represent a point with X-and y-coordinates. The class contains: The data fields x and y that represent the coordinates with getter methods. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. A method named distance that returns the distance from this point to a specified point of the MyPoint type. A method named distance that returns the distance from this point to another point with specified x- and y-coordinates. A static method named distance that returns the distance from two MyPoint objects. Draw the UML diagram for the class then implement the class. Write a test program that creates the two points (0, 0) and (10, 30.5) and displays the distance between them.

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…
