Consider the following Java program. Which line give the "TestFx" class access to the "Button" class import javafx.application.Application; import javafx.scene.Scene; import javafx.state.Stage; import javafx.application.Platform; import javafx.scene.layout.BorderPane; import javafx.scene.layout.HBox; import javafx.scene.control.Button; public class TestFx extends Application { public void start(Stage.stage)  {    Button quitButton = newButton('Quit");     quitButton.setOnAction(e -> Platform.exit());     HBox buttonBar = new HBox(quitButton);     BorderPane root = new BorderPane();     root.setBottom(buttonBar);    Scene.scene = new Scene(root, 100, 50);    stage.setScene(scene);    stage.show(); } public static void main(String[] args)  {     launch(args);  } }   a. Button quitButton = newButton("Quit"); b. import javafx.application.Application c. import javafx.scene.control.Button; d. root.setBottom(buttonBar); e. public class TestFx extends Application

Write a modified Button class that creates circular buttons. Call your class CButton and implement the exact same methods that are in the existing Button class. Your constructor should take the center of the button and its radius as normal parameters. Place your class in a module called cbutton . py. Test your class by modifying roller . py to use your buttons.

You are required to create above frame, Create a class HelloFrame and extend it from JFrame Inside HelloFrame  declare 3 textfields for taking string input for name, email and number variables 1 textarea to write a message. Create a button “Submit” which should submit the form. Now create a public constructor for HelloFrame inside which You should call super("Hello Java");    //used to set title of the frame setSize(700, 400);          //set length and width of the frame create a label which should display the method "Contact US Panel" similarly create labels for showing name, email, number. Add textfields and button to JFrame. Run the code and make sure the output should be as above frame.

Create a class RectangleExample in eclipse. Copy the following code into the class. RectangleExample.java  package mypackage; import javafx.application.Application; import javafx.scene.Group; import javafx.scene.Scene; import javafx.stage.Stage; import javafx.scene.shape.Rectangle; public class RectangleExample extends Application { Rectangle rect1, rect2; @Override public void start(Stage stage) { Group root = new Group(); //Drawing a Rectangle rect1 = new Rectangle(); //Setting the properties of the rectangle rect1.setX(20.0f); rect1.setY(20.0f); rect1.setWidth(300.0f); rect1.setHeight(10.0f); rect1.setFill(javafx.scene.paint.Color.RED); //Add to a Group object root.getChildren().add(rect1); //Drawing a Rectangle rect2 = new Rectangle(); //Setting the properties of the rectangle rect2.setX(20.0f); rect2.setY(40.0f); rect2.setWidth(200.0f); rect2.setHeight(10.0f); rect2.setFill(javafx.scene.paint.Color.GREEN); //Add to a Group object root.getChildren().add(rect2); //Creating a scene…

Please add the code after this one. The code has to be in java eclipse. Please add comments in what you are doing.

please code in java..refer the 2 codes BankAccount and AccountTest.. BankAccount source code is given below and AccountTest source code is added in image  Question is  to add code to be able to lock the account. for example if someone withdraws a certain amount of money the accounts locks, etc   /**   The BankAccount class simulates a bank account.*/ public class BankAccount{   private double balance;      // Account balance    /**      This constructor sets the starting balance      at 0.0.   */    public BankAccount()   {      balance = 0.0;   }      /**      This constructor sets the starting balance      to the value passed as an argument.      @param startBalance The starting balance.   */    public BankAccount(double startBalance)   {      balance = startBalance;   }    /**      This constructor sets the starting balance      to the value in the String argument.      @param str The starting balance, as a String.   */    public BankAccount(String str)   {      balance =…

Code  . Make a java class Vehicle.a. The class ought to have two fields:I. no_of_seats and no_of_wheels.b. Make two itemsI. Bike and Vehicle for this class.c. Your result ought to show the depictions for Vehicle and Bike.

In Java!!!!!This is a multi-part question. Consider the following UML diagram on attached image: 1.Write Java classes corresponding to the UML diagram. 2. Write getters and setters for all classes 3. Write non-default constructors for each class that initializes all instance variables to values passed as arguments to the constructor 4. Write toString method for each class 5. Modify Vehicle class to maintain inventory (list of all vehicles created) and print the list. What variable(s) you need to add? What additional method(s) you need? What else needs to be modified in the Vehicle class? Do you need to modify any of the descendant classes and explain your answer (if not: why not; if yes, describe what changes). Vehicle {Abstract} manufacturer:String - color:String Car Truck TwoWheeler {Abstract} -numberOfDoors:int -numberOfAxels:int -passengerSeats:int -fuelType:String -fuelLevel:int -fuelType:String -numberOfSeats:int -fuelLevel:int Truck Motorcycle -numberOfAxels:int -fuelType:String…

We already have the address and vehicle class for the system below. We will need a CarShow class with IsSanctioned() method, Owner class with IsOwner method and a main class that creates objects and implements all our existing classes. Use the class diagrams. Make sure to include respective attributes, setters, getters and constructors in your code Explain your code in a few words.
