Explanation of Solution

Purpose of the given code:

The purpose of the given code is resizing objects placed inside based on the window size. In the given code a rectangle and circle is placed inside the stack pane, the object gets resized based on the window size.

Given code:

//import the required packages

import javafx.application.Application ;

import javafx.scene.paint.Color ;

import javafx.scene.shape .Circle ;

import javafx.scene.shape.Rectangle ;

import javafx .stage.Stage;

import javafx.scene.Scene;

import javafx .scene.control .Label ;

import javafx.scene.layout.StackPane ;

//define the method ResizableCircleRectangle

public class ResizableCircleRectangle extends Application

{

//Create a circle

private Circle circle= new Circle( 60) ;

//new rectangle gets created

private Rectangle rectangle = new Rectangle( 120 , 120);

// Place clock and label in border pane

private StackPane pane = new StackPane() ;

@Override

// Override the start method in the Application class

public void start(Stage primaryStage)

{

//set the fill color of circle

circle.setFill (Color.GRAY) ;

//set the fill color of rectangle

rectangle.setFill (Color.WHITE);

//set the stroke color

rectangle.setStroke(Color.BLACK);

//add all to the pane

pane.getChildren() .addAll (rectangle, circle);

//new scene gets created and placed on the stage

Scene scene = new Scene (pane , 140, 140) ;

//set the title of the stage

primaryStage.setTitle( "ResizableCircleRectangle" );

//the scene gets placed on the stage

primaryStage .setScene(scene);

//the stage gets displayed

primaryStage.show();

//set the height property

pane.widthProperty().addListener(ov ->resize()) ;

//set the width property

pane.heightProperty() .addListener(ov -> resize());

}

//define the method resize

private void resize()

{

//define length of the pane

double length= Math...
