- Implement the following classes: Polygon numSide: int /* constructor */ /* accessor-mutator */ + area (): double + perimeter (): double Triangle sideA: double sideB: double sidec: double /* constructor */ /* accessor-mutator */ + area () : double + perimeter (): double Create an object for Triangle class and invoke area and perimeter method. Input Format Take triangle sides (sideA,sideB,sideC) as input from user. Constraints For Triangle, sideB+sideC > sideAShape -width: double -length: double +allmutatorMethods Shapes2D Shapes3D -height:double *calSize():double +calVolume():double 1. Define class Shape, 2DShape and 3DShape as per UML class diagram given. 2. Define all mutator methods(set and get) for all classes. 3. Define methods calArea() with formula area - width * length for 2DShapes. 4. Define methods calArea() with formula calvolume, volume = width*length*height for 3DShapes. In the main program, declare and set data in 1 object of 3DShapes. Create an array OR ArrayList of 2DShapes, set and display the info of all objects as shown in the output. 5.Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:
- Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle. Shape (abstract) int rows char character Shape() Shape(int x, char c) int get rows() char getCharacter() void setRows(int x) void setCharacter(int x) void draw(int x, int y) (abstract) Square() Square(int x, char ch) void…Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).2D Graphics You have learned 2D graphics from DrawPanel.java (see code below) // DrawPanel.java // Using drawLine to connect the corners of a panel. import java.awt.Graphics; import javax.swing.JPanel; public class DrawPanel extends JPanel { // draws an X from the corners of the panel public void paintComponent( Graphics g) { // call paintComponent to ensure the panel displays correctly super.paintComponent( g ); int width = getWidth(); // total width int height = getHeight(); // total height // draw a line from the upper-left to the lower-right g.drawLine(0, 0, width, height); // draw a line from the lower-left to the upper-right g.drawLine(0, height, width, 0); } // end method paintComponent } // end class DrawPanel 3. Write a Java program that does all of the following 3 actions. a. draws a line from (20, 50) to (50, x) of length 50. Compute the value x first. b. draws a rectangle with (20, 50) as the lower left corner, height 10 and width 100. c. fills a rectangle with (20, 50) as…
- Create a RightTriangle class given the following design: RightTriangle variables: base, height methods: 2 constructors, 1 that set default values and another that accepts to parameters. setBase - changes the base. Requires one parameter for base. setHeight - changes the height. Requires one parameter for height. getBase - returns the triangle base. getHeight - returns the triangle height. area - returns the area of the triangle (1/2bh) given the current base and heightJava - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66Assume Student and GradeBook classes are defined as follows: public class Student { int id; double testsMarks[]; public double getAverage(){ double sum = 0; for(double marks : testsMarks) { sum+=marks; } return sum/testsMarks.length; } } import java.util.ArrayList; public class GradeBook { String subject; ArrayList<Student> students; public Student getStudentWithMinAverage(){ } } Define the body of getStudentWithMinAverage method that shall return the student object from students ArrayList who got minimum average marks in the class. (Please write minimum code and make use of provided code, making no change in classes' structure)
- Given the following class definition: class Point2d { private int x, y; public Point2d () { X = 0; y = 0; } public Point2d (int i, int j) { X = i; y = j; } public void SetX (int i) { x = i; } public void SetY (int j) { y = j; } public int GetX () { return x; public int GetŸ () { return y; } public String toString() { return '[' + x + ", } + y + ']'; } } Use inheritance to create a class, Point3d, with any additional appropriate data and/or functions.class Point { private: int x, y ; public: : x(u), y(v) {} Point (int u, int v) int getX) { return x; } int getY () { return y; } void doubleVal() { *= 2: y *= 2; } }; int main () { const Point myPoint (5, 3) myPoint.doubleVal() ; cout << myPoint.getX() << " " return 0; << myPoint.getY() << "\n"; }JAVA – color: String – make: String – model: String – msrp: double + Car() + Car(color: String, make: String, model: String, msrp: double) + getColor() : String + setColor(color : String ) : void + getMake() : String + setMake(make: String ) : void + getModel() : String + setModel(model: String ) : void + getMsrp () : double + setMsrp(msrp: double) : void + toString(): String The Car class will have four attributes/instance variables/fields and 11 methods. CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.
