Please use JAVAFX application for this problem and not Java Swing. Please write the code in one single class, create methods as needed. Write a JavaFX GUI program that will serve as a mileage calculator for a trip. The program should calculate overall mileage as well as individual fuel ratings along individual trip legs (up to 5) based on user-entered values for mileage and fuel usage. Empty trip legs should not be included in the calculations and all values should be computed and displayed once a Button is pressed. There should also be a Ul control (CheckBox or RadioButtons with a ToggleGroup) to switch between miles per gallon and liters per 100 kilometers. If numbers are already entered for both mileage and fuel usage, the program should auto-convert those numbers, change any appropriate labels/text, and recalculate using the already entered values. For instance, a trip leg with 500 miles using 15 gallons should return a result of 33.33 mpg. If the user switched to L/100KM, the program should recalculate that leg using 804.67 KM and | 56.78 liters for 7.06 L/100KM. This program should: Accept user-entered miles and fuel usage for individual legs of a trip. Calculate both that leg's mileage, and the overall mileage for the entire trip. Blank entries should not be included in calculations. Assume that there is a maximum of 5 legs per trip. Have a Button that, when clicked, calculates, and displays the fuel rating calculation. There should be some UI control to allow switching between MPG and L/100KM. If values are already entered, using this UI controls should auto-covert existing values and recalculate fuel rating. There should be some type of help system to inform the user of program usage. This could be a simple as text on the interface, or a separate stage that's activated from a button or other control. You should: Effectively use panes and spacing/padding/alignment options to present a clear and understandable interface; think of usability when designing. Use error prevention/detection. Test all cases (especially blankull values in text fields) and handle them appropriately. Please use JAVAFX application for this problem and not Java Swing.
