Expert Answer


For creating a color picker , We should handle dynamic action events for changing colors and color should be displayed in color palette.

//Starting of program

import javafx.application.Application;

import javafx.event.ActionEvent;

import javafx.event.EventHandler;

import javafx.geometry.Insets;

import javafx.scene.Scene;

import javafx.scene.control.ColorPicker;

import javafx.scene.layout.FlowPane;

import javafx.scene.paint.Color;

import javafx.scene.shape.Circle;

import javafx.stage.Stage; //imports all required modules like Stage,scene to the program.

public class ColorPickerUsingScene extends Application { /*This class should extend Application so that every method and variables can be used by ColorPickerUsingScene*/

@Override //Warning are avoided using this keyword.

public void start(Stage stage) {

final ColorPicker colorPicker = new ColorPicker(); /*ColorPicker object must be declared final*/


final Circle circle = new Circle(10);

circle.setFill(colorPicker.getValue()); /*Circle object is initialized and color is picked from colorPicker*/

colorPicker.setOnAction(new EventHandler<ActionEvent>() {


public void handle(ActionEvent event) { /*Action Event is creacted to control colors which are changed*/




FlowPane fp = new FlowPane();

fp.setPadding(new Insets(5));


fp.getChildren().addAll(circle, colorPicker); //flowpane methods are initialized

Scene scene = new Scene(fp, 500, 250); /*new Scene is created with Flowpane as one of parameters*/

stage.setTitle(“Color Picker Using Scene Builder “);



public static void main(String[] args) {

launch(args); // set colors after default colors by calling launch.



//End of program

Note: This program will require installation of javafx along with other required files on your computer.
