: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate. Also, write a test program to test the various operations on the point.
Q#2: Create a class named “Rectangle” having length and width as attribute. There should be behaviors to set the values of length and width (individually and collectively), and get their values individually. There should also behavior to display the perimeters and area of the rectangle. Create another class named as Main which have two objects of Rectangle (r1, r2) having length (3.2, 20) and width (4.5, 36) respectively. Also display the length, width, perimeter and area of both rectangles.
Sammy's Seashore Supplies rents beach equipment such as kayaks, canoes, beach chairs, and umbrellas to tourists. In Chapter 3, you created a Rental class for the company. The Rental class contains two public final static fields that hold the number of minutes in an hour and the hourly rental rate ($40), and four private fields that hold a contract number, number of hours for the rental, number of minutes over an hour, and the price. It also contains two public set methods and four public get methods.
Now, modify the Rental class to contain two overloaded constructors.
One constructor accepts a contract number and number of minutes as parameters. Pass these values to the setContractNumber() and setHoursAndMinutes() methods, respectively. The setHoursAndMinutes() method will automatically calculate the hours, extra minutes, and price.
The other constructor is a default constructor that passes "A000" and 0 to the two-parameter constructor.

- Python In this assignment, a game called treasure hunt will be written object oriented.There are 3 types of treasures in the game. Diamond, Emerald and Gold. Diamond is 100 points, Emerald 70 points and Gold is 50 points.There are thieves in the game that will prevent you from hunting for treasure. Encountering a thief they steal some of your treasure. You will randomly generate which thief will steal from which treasure and how much.At the beginning of the game, the player has no treasure. X, Y, Z and H will be randomly identified at the start of the game. Define X Diamonds, a random number between X -> 100-200.Let a random number be defined between Y Emerald Y -> 100-200.Define a random number between Z Gold Z -> 100-200.You will define H thieves.

- in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car.

- The Spider Game Introduction: In this assignment you will be implementing a game that simulates a spider hunting for food using python. The game is played on a varying size grid board. The player controls a spider. The spider, being a fast creature, moves in the pattern that emulates a knight from the game of chess. There is also an ant that slowly moves across the board, taking steps of one square in one of the eight directions. The spider's goal is to eat the ant by entering the square it currently occupies, at which point another ant begins moving across the board from a random starting location. Game Definition: The above Figure illustrates the game. The yellow box shows the location of the spider. The green box is the current location of the ant. The blue boxes are the possible moves the spider could make. The red arrow shows the direction that the ant is moving - which, in this case, is the horizontal X-direction. When the ant is eaten, a new ant is randomly placed on one of the…arrow_forwardJavaStudents will be creating a simple trivia game for two players. The program will work like the following: Starting with player 1, each player gets a turn answering 5 trivia questions (There are 10 questions, 5 for each player). When a question is displayed, four possible answers are also displayed. Only one of the answers is correct, and if the player selects the correct answer, he or she earns a point.After answers have been selected for all of the questions, the program displays the number of points earned by each player and declares the player with the highest number of points the winner.You are to design a Question class to hold the data for a trivia question. The Question class should have String fields for the following data: A trivia questionPossible answer 1Possible answer 2Possible answer 3Possible answer 4The number of the correct answer (1,2,3, or 4)The Question class should have appropriate constructor(s), accessor, and mutator methods.

This class should also override the __str__ method in a nicely formatted way. Customer: Represents a customer at the store. It should have three attributes: a String for the customer's name, a Boolean for the customer's preferred status, and a list of 5 indexes to hold Item objects. Include the following methods: make_purchase: accepts a String and a double as parameters to represent the name and price of an item this customer is purchasing. Create a new Item object with this info and append it to the internal list.
