- Given the Solid class, extend it with: Pyramid Cylinder RectangularPrism Sphere Make sure to create the constructor and override the volume and surfaceArea methods. Also extend RectangularPrism with Cube. HINT: You can look up formulas for how to compute the volume and surface area of a certain type of shape online. ========================================== public class SolidTester{public static void main(String[] args){String name;double volume;double surfaceArea; // Pyramid constructor should take name, length, width, height// in that orderPyramid pyramid = new Pyramid("My pyramid", 1, 3, 5);name = pyramid.getName();volume = round(pyramid.volume(), 2);surfaceArea = round(pyramid.surfaceArea(), 2);System.out.println("Pyramid '" + name + "' has volume: " + volume +" and surface area: " + surfaceArea + "."); // Sphere constructor should take name then radiusSphere sphere = new Sphere("My sphere", 4);name = sphere.getName();volume = round(sphere.volume(), 2);surfaceArea =…*Create a rectangle class using all methods given below.* *Use Java* Class Rectangle will have the following instance variables: •x –a double that represents the x coordinate of the lower left vertex of the rectangle •y –a double that represents the y coordinate of the lower left vertex of the rectangle •width –a double that represents the width of the rectangle •height–a double that represents the height of the rectangle •color –a String that represents the color of the rectangle •filled –a boolean variable that is true if the rectangle is filled, and false if it is not Rectangle constructor: The constructor should be: Rectangle (double x, double y, double height, double width, String color, boolean filled) Parameters are, in order,the x and y coordinates of the lower left corner, the height, the width, and the color of the rectangle. The constructor should check that these values represent a valid rectangle. If they do, then it should initialize the rectangle to these values.…Design an application that does the following: A Solid can be a FlatSurfaceSolid or a CurvedSurfaceSolid. Every solid will have a volume. The method volume will be polymorphic. A solid has faces, vertices and edges. A flat-surface solid also has a variable called side which represents the length of the side. A curved-surface solid also has a radius. A Cube is a FlatSurfaceSolid. A cube has 6 faces, 8 vertices and 12 edges. It will have a side. A Sphere is a CurvedSurfaceSolid. It has 1 face, 0 vertices and 0 edges. It will have a radius. Create an ArrayList of solids (driver file named YourLastNameCISC231Q1.java). The arraylist will have 4 elements – 2 cubes (one with side length 3 and another will side length 4) and 2 spheres (one with radius 3 and another with radius 4). Create a driver class to instantiate an array of solids and display the details of each solid along with the volume of each solid.
- Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.Write a class CircularArrayQueue such that all the following methods are implemented: 1. enqueue 2. dequeue 3. first 4. isEmpty 5. size 6. toStringWrite a Rectangle class. Its constructor should accept length and width as a parameter. It should have methods that return its length, width, perimeter, and area. (Use Java) Show a demonstration where you create two separate rectangles.
- You will create a class called Square. Length will represent the length of one side which is an integer.You should create the constructor, an instance variable, a getter method for the length of a side, a getArea method and a toString method. The area of a square = length * length.Your toString method should be written such that it would return a String of the form "Square with side length: 8” (if the side length was 8) public class Square { //create one instance variable called length //create the constructor with one parameter //create your getter method to get the length of one side with return type integer //create the getArea method with return type integer //create the toString method }Create a class that represents the grade distribution for a given course. In this class you should write methods to perform the following tasks: Read the number of each of the letter grades A, B, C D and F Set the number of letter grades A, B, C, D and F Return the total number of grades Return the percentage of each letter grade as a whole number between 0 and 100 inclusive Draw a bar graph of the grade distributionThe graph should have five bars, one per grade. Each bar can be a horizontal row of asterisks, such that the number of asterisks in a row is proportionate to the percentage of grades in each category. For example, let on asterisk represent 2%, so 50 asterisks correspond to 100%. Mark the horizontal axis at 10% increments from 0 to 100% and label each line with a letter grade.For example, if the grades are entered as 1A, 4B's, 6C's, 2D's and 1 F, the total number of grades is 14, the percentage of As os 7, the percentage of Bs is 29, the percentage of Cs is 43, the…Create a class that represents the grade distribution for a given course.

- Using SceneBuilder and Javafx create a Elevator Simmulation. The Simulation should include polymorphism and object-oriented programming. The simulation should have 4 types of Passengers: Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements. VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators. Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators. Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. The simulation should also have 4 types of Elevators: StandardElevator: This is the most common type of elevator and has a request…Look at the API of the Point class and find out how to construct a Point object. Write a Java program “PointTester”, that constructs two points with coordinates (3, 4) and (–3, –4). Find the distance between them, using the distance method. Print the distance, as well as the expected value. (You may draw a sketch on graph paper to find the value you will expect.) - Update your program so it randomly select coordinate points (x,y), where −50 ≤ ? ≤ 50 ??? ? ∈ [−90, 90].*** Please help me solve this in the Java language.
