- JAVA PROGRAMMING Write two java files for this assignment: Circle.java, and Main.java. The Circle.java file will create an actual class. The Circle class: MEMBER VARIABLE double radius double x double y Eight methods: Six of the methods are simple: getter’s and setter’s for x, y, and radius. There should also be a getArea method that returns the area (derived from the radius) A doesOverlap method. This method should accept a Circle as an argument, and return true if this circle overlaps the circle that the method was invoked on. [Note: two circles overlap if the sum of their radius' is greater than or equal to the distance between their centers.] void setX(double value) double getX() void setY(double value) double getY() void setRadius(double value) double getRadius() double getArea() boolean doesOverlap(Circle otherCircle) second class will be the typical replit Main class, with its static main method .It should contain code that tests the Circle class. submit code that…arrow_forwardon JAVA language Define a class named Wall. The class should have two private double variables, one to store the length of the Wall and another to store the height ._Create adefault constructor that sets the length& height to 0, create a second constructor with input parameters for the of the data variables and third copy constructor.Add accessor and mutator functions to read and set both variables Add another function that returns the area of the Wall as double .Write program that tests all your constructors and functions for at least three different Wall objectsarrow_forwardDice Rolling Class In this problem, you will need to create a program that simulates rolling dice. To start this project, you will first need to define the properties and behaviors of a single die that can be reused multiple times in your future code. This will be done by creating a Dice class. Create a Dice class that contains the following members: Two private integer variables to store the minimum and maximum roll possible. Two constructors that initialize the data members that store the min/max possible values of rolls. a constructor with default min/max values. a constructor that takes 2 input arguments corresponding to the min and max roll values Create a roll() function that returns a random number that is uniformly distributed between the minimum and maximum possible roll values. Create a small test program that asks the user to give a minValue and maxValue for a die, construct a single object of the Dice class with the constructor that initializes the min and max…arrow_forward
- Area of a rectangle = length * width Create a Class that calculates and prints out the area of a rectangle. Then write code that creates an object of this Class in which given the length and width, it calculates and prints out the area of a rectangle. Your output should look like this: Area of rectangle: 87arrow_forward(Physics: acceleration) Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: a = (v1 - v0) / t Here, v0 is the starting velocity in meters per second, v1 is the ending velocity in meters per second, and t is the time span in seconds. Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration. Class Name: Exercise01_02Extraarrow_forwardNutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…arrow_forward
- PLEASE CODE IN PYTHON PLEASE USE THE CLASS FUNCTION In python, create a LunchOrder application that prompts the user for the number of hamburgers, salads, french fries, and sodas and then displays the total for the order. The LunchOrder application should includea Food object with a constructor that accepts the price, fat, carbs, and fiber for an item. Food methods should return the price of the item and return the fat, carbohydrates, and fiber. Use the chart below forfood prices and nutrition information:arrow_forwardProblem (Circle.java) Implement a class called Circle for representing a circle. The circle has two data members, a Point object representing the center of the circle and a float value representing the radius. Include appropriate constructors for your Circle class. Encapsulate it. Also include methods for finding the area and circumference of the circle. area = pi * radius * radius circumference = 2 * pi * radius. (You may use the static constant pi in the Math class) 5. Override the toString() and equals().arrow_forwardThe 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_forward
- 2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.arrow_forward:Define and implement class Employee. This class should contain the following fields: first name, last name, employee id, hourly pay. This class should contain getters and setters for all its attributes. This class also needs at least one constructor. Implement method computePay() in this class. This method should accept an integer number of hours the employee worked as an input argument and return a floating point value indicating the pay the employee earned. If the number of hours is invalid (e.g. a negative number) this method should throw NumberFormatException. If the number of hours is over 40 then this method should throw a custom exception named TooManyHoursWorkedException. Remember that you will have to define your own exception class for this. Save this class and its definition into a file named Employee.java. Define and implement class EmployeeTest.This class should implement main() method. In the body of the main() method you should create an instance of Employee with the…arrow_forwardTime This class is going to represent a 24-hour cycle clock time. That means 0:0:0 (Hour:Minute:Second) is the beginning of a day and 23:59:59 is the end of the day. This class has these data members. int sec int min int hourarrow_forward
