Question

Modify this program and draw something interesting. Maybe a car, a character, a tree, a happy face or anything else you like. Have at least 3 or 4 drawing commands in the program. Do some research on the Oracle web site to see what other JavaFX shapes you can include.Extra credit will be given if you include many different shapes and text. Include different fonts and different styles (Bold, Italic etc.) Be creative.

Please find the code below:

Smiley.java

package gui;

import javafx.application.Application;

import javafx.geometry.Insets;

import javafx.scene.Scene;

import javafx.scene.layout.Pane;

import javafx.scene.layout.StackPane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Arc;

import javafx.scene.shape.ArcType;

import javafx.scene.shape.Circle;

import javafx.scene.shape.Ellipse;

import javafx.scene.shape.Polygon;

import javafx.stage.Stage;

public class Smiley extends Application {

public void start(Stage primaryStage) {

// Create a stack pane

StackPane stackPane = new StackPane();

StackPane stackPane2 = new StackPane();

// Crate a pane

Pane pane = new Pane();

stackPane2.setPadding(new Insets(40, 40, 40, 40));

// Create a circle and place it in a stack pane

Circle circle = getCircle();

stackPane.getChildren().add(circle);

// Create a Polygon and place it in a stack pane

Polygon polygon = getPolygon(circle);

stackPane.getChildren().add(polygon);

// Create two ellipse

Ellipse ellipse1 = getEllipse(circle);

ellipse1.setCenterX(circle.getRadius() - circle.getRadius() / 2.5);

Ellipse ellipse2 = getEllipse(circle);

ellipse2.setCenterX(circle.getRadius() + circle.getRadius() / 2.5);

// Create two circles

Circle circle2 = getCircle(ellipse1);

circle2.setFill(Color.BLUE);

Circle circle3 = getCircle(ellipse2);

circle3.setFill(Color.BLUE);

// Create an Arc

Arc arc = getArc(circle);

// Place nodes in a pane

pane.getChildren().addAll(stackPane, ellipse1,

ellipse2, circle2, circle3, arc);

// Place pane in a stack pane

stackPane2.getChildren().add(pane);

// Create a scene and place it in the stage

Scene scene = new Scene(stackPane2);

primaryStage.setTitle("How to laugh"); // Set the stage title

primaryStage.setScene(scene); // Place the scene in the stage

primaryStage.show(); // Display the stage

}

/** Return a Arc of specified properties */

private Arc getArc(Circle c) {

Arc a = new Arc(c.getRadius(), c.getRadius() * 1.30,

c.getRadius() / 2, c.getRadius() / 4, 0, -180);

a.setType(ArcType.OPEN);

a.setFill(Color.ORANGE);

a.setStroke(Color.BLACK);

return a;

}

/** Return a circle of specified properties */

private Circle getCircle(Ellipse e) {

Circle c = new Circle(e.getCenterX(), e.getCenterY(),

e.getRadiusY() - (e.getRadiusX() - e.getRadiusY()));

return c;

}

/** Return an Ellipse of specified properties */

private Ellipse getEllipse(Circle c) {

Ellipse e = new Ellipse();

e.setCenterY(c.getRadius() - c.getRadius() / 3);

e.setRadiusX(c.getRadius() / 4);

e.setRadiusY(c.getRadius() / 3 - 20);

e.setStroke(Color.BLACK);

e.setFill(Color.WHITE);

return e;

}

/** Return a Polygon of specified properties */

private Polygon getPolygon(Circle c) {

double length = c.getRadius() / 4;

Polygon p = new Polygon(c.getCenterX(), c.getCenterY() - length,

c.getCenterX() - length, c.getCenterY() + length, c.getCenterX() + length,

c.getCenterY() + length);

p.setFill(Color.BROWN);

p.setStroke(Color.GREEN);

return p;

}

/** Returns a circle of specified properties */

private Circle getCircle() {

Circle c = new Circle();

c.setRadius(150);

c.setStroke(Color.BLACK);

c.setFill(Color.WHITE);

c.setFill(Color.LIGHTBLUE);

return c;

}

}

output:
