Question

WRITE A JavaFX APPLICATION THAT DRAWS A PICTURE OF A FLOWER.

Use thick lines for stalks and rotated ellipses for petals. Put the sky and the ground as background. Don’t worry artistic quality, it should look simple. It should take about 45 to 75 statements.

Also, have some line-by-line documentation that says what is going on, e.g., // draw petal // draw ground // draw leaf

The snowman program should be used as a GUIDE.

Snowman code :

import javafx.application.Application;

import javafx.scene.Group;

import javafx.scene.Scene;

import javafx.scene.shape.*;

import javafx.scene.paint.Color;

import javafx.scene.text.Text;

import javafx.stage.Stage;

public class SnowmanFX extends Application

{

public void start( Stage primaryStage )

{

Ellipse base = new Ellipse( 80, 210, 80, 60 );

base.setFill( Color.WHITE );

Ellipse middle = new Ellipse( 80, 130, 60, 40 );

middle.setFill( Color.WHITE );

Circle head = new Circle( 80, 70, 30 );

head.setFill( Color.WHITE );

  

Circle rightEye = new Circle( 70, 60, 5 );

rightEye.setFill( Color.BLACK );

Circle leftEye = new Circle( 90, 60, 5 );

leftEye.setFill( Color.BLACK );

Line mouth = new Line( 70, 80, 90, 80 );

  

Circle topButton = new Circle( 80, 120, 6 ) ;

topButton.setFill( Color.RED );

Circle botButton = new Circle( 80, 140, 6 ) ;

botButton.setFill( Color.RED );

  

Line leftArm = new Line( 110, 130, 160, 130 );

leftArm.setStrokeWidth( 3 );

Line rightArm = new Line( 50, 130, 0, 100 );

rightArm.setStrokeWidth( 3 );

  

Rectangle stovepipe = new Rectangle( 60, 0, 40, 50 );

Rectangle brim = new Rectangle( 50, 45, 60, 5 );

Group hat = new Group( stovepipe, brim );

hat.setRotate( 15 );

hat.setTranslateX( 10 );

  

Group body = new Group( base, middle, head );

Group face = new Group( leftEye, rightEye, mouth );

Group buttons = new Group( topButton, botButton );

Group arms = new Group( leftArm, rightArm );

  

Group snowman = new Group( body, face, buttons, arms, hat );

snowman.setTranslateX( 170 );

snowman.setTranslateY( 50 );

  

Circle sun = new Circle( 0, 0, 30 );

sun.setFill( Color.GOLD );

sun.setTranslateX( 60 );

sun.setTranslateY( 60 );

  

Rectangle ground = new Rectangle( 0, 250, 500, 100 );

ground.setFill( Color.STEELBLUE );

  

Group root = new Group( ground, sun, snowman );

  

Scene scene = new Scene( root, 500, 350, Color.LIGHTBLUE );

  

primaryStage.setTitle( "Snowman" );

primaryStage.setScene( scene );

primaryStage.show();

}

}
