I need a modification on the following program attached. Here is the modification I need. This is JavaFX

(Tip Calculator Modification)The Tip Calculator app from Section 25.5 does not need a Button to perform its calculations. Reimplement this app to use property listeners to perform the calculations whenever the user modifies the bill amount or changes the custom tip percentage. Also use a property binding to update the Label that displays the tip percentage.

This question was already asked and answered but the answer does not allow the tip percentage slide bar to slide after an amount is put in, so it is not correct. The only modifications should be in the TipCalculatorController.java class.

I don't see how I can upload the code here, so I will give the link to the previous question and answer:

There is no academic violation in this question. I will cancel my account if I cannot ask a simple question.
