I have been given the following code to create a progress bar and it needs to be adjusted to run on NetBeans

import javafx.application.Application; import javafx.geometry.Insets; import javafx.stage.Stage; import javafx.scene.Scene;

//Import for the progress bar. import javafx.scene.control.ProgressBar;

//Import for the progress indicator. import javafx.scene.control.ProgressIndicator;

//Labels and buttons. import javafx.scene.control.Label; import javafx.scene.control.Button;

//Imports for layout. import javafx.scene.layout.GridPane;

/** * * @author Anita Murphy */

public class Progress2 extends Application { //Declare a progress bar. ProgressBar progBar;

//Declare a progress indicator. ProgressIndicator progIndicator;

//Labels Label lblProgress;

//Buttons Button btnIncrease, btnDecrease;

public void init(){

//Create a progress bar. 1.0 is full scale. Give it 0. progBar = new ProgressBar(0);

//Construct a progress indicator. progIndicator = new ProgressIndicator(0);

//Construct labels and buttons. lblProgress = new Label("Progress:"); btnIncrease = new Button("Increase"); btnDecrease = new Button("Decrease");

//Set preferred widths for the buttons. btnIncrease.setPrefWidth(70); btnDecrease.setPrefWidth(70);

//Set the preferred width of the progress bar. progBar.setPrefWidth(300);

//Set a style. Show a green progress bar. progBar.setStyle("-fx-accent: green;");

//Handle events on the increase button. btnIncrease.setOnAction(ae -> {

//Get the current progress. double progValue = progBar.progressProperty().get();

//Increase it by 0.05. progValue = progValue + 0.05; if(progValue >= 0.7){

//Set a style. Show a green progress bar. progBar.setStyle("-fx-accent: red;"); progIndicator.setStyle("-fx-accent: red;"); }//if else { //Set a style. Show a green progress bar. progBar.setStyle("-fx-accent: green;"); progIndicator.setStyle("-fx-accent: green;"); }//else

//Don't let the progress bar or indicator go off scale. if(progValue < 0.95){

//Set the new (increased) progress. progBar.setProgress(progValue);

//Set the progress indicator. progIndicator.setProgress(progValue); } else{ progValue = 1; progBar.setProgress(progValue); progIndicator.setProgress(progValue); }//else });

@Override public void start(Stage primaryStage) throws Exception {

//Set the title. primaryStage.setTitle("Progress Bar 2");

//Create a gridpane. GridPane gp = new GridPane();

//Set the hgap, vgap and padding. gp.setHgap(10); gp.setVgap(15); gp.setPadding(new Insets(10));

//Add the controls to the gridpane. gp.add(lblProgress, 0, 0); gp.add(progBar, 1, 0); gp.add(progIndicator, 2, 0); gp.add(btnIncrease, 2, 1); gp.add(btnDecrease, 2, 2);

//Create a scene. Scene scene = new Scene(gp, 470, 150);

//Set the scene. primaryStage.setScene(scene);

//Show the stage. primaryStage.show(); }

//start()
