- 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:arrow_forwardPolymorphism: Is it a phrase you're acquainted with?arrow_forwardmain Application public class Application { public static void main(String[] args) {//Create library objectLibrary l = new Library();//Add booksl.add(new Kids("KidsBook1", "author1", 18, 5));l.add(new Kids("KidsBook2", "author2", 15, 7));l.add(new Kids("KidsBook3", "author3", 10, 9));l.add(new Scientific("ScientificBook1", "author1", 12));l.add(new Scientific("ScientificBook2", "author2", 13));//Borrower objectsBorrower b1 = new Borrower("Borrower1", 1, 10, 2);Borrower b2 = new Borrower("Borrower2", 2, 6, 5);//Borrower1 borrow 2 booksif (b1.getMaxBookNum() <= b1.getSerialNumbers().size()) {System.out.println("Reached maximum borrowings!!!");} else {if (l.borrow(18, b1)) {b1.borrow(18);}}if (b1.getMaxBookNum() <= b1.getSerialNumbers().size()) {System.out.println("Reached maximum borrowings!!!");} else {if (l.borrow(15, b1)) {b1.borrow(15);}}//Borrower2 borrow 1 bookif (b2.getMaxBookNum() <= b2.getSerialNumbers().size()) {System.out.println("Reached maximum borrowings!!!");}…arrow_forward
