So i know how to do this using Swing but how to i convert swing code to JavaFX? Here is a sample code so far that i must convert to JavaFx.

Executable Code

import java.awt.BorderLayout;

import java.awt.Dimension;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.*;

import javax.swing.plaf.ColorUIResource;

import java.text.NumberFormat;
