Please write java codes for a basic Fx GUI java solution with the following 3 components: public class SimpleGUI extends Application { // part 1: create an ArrayList ( or array) to store customer information. Your ArrayList (or array) has to be in the correct place in the GUI program to receive full credits for this part. // Part 2: create a simple button to add a new customer object when clicked. Again, make sure your button is inside the correct GUI method(s). // Part 3: write a handler to create a new customer object and add/insert that object into the ArrayList (or array) you create in Part#1 of this same test question. } // end of the GUI java code solution. Please add java comments to explain your solutions. For examples, do you place the ArrayList inside/outside the main()/start()? How do you link the button to the correct handler? //You do NOT need to write detail Customer.java codes here in your solution.
