Question

How could I take this code and make a JavaFX program with the same results?

import java.util.Scanner;

    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {

        int planIndex = getDataPlan();

        System.out.println("Total Cost           : $"+String.format("%.2f",totalCost));

    }

    // ask user for a data plan until user selects teh right plan

            int choice = scanner.nextInt();
