Question

JavaFX application for the Sublime Sandwich Shop. The user can order sandwiches by using list boxes and the application displays the price. Each sandwich should allow a choice of at least three main ingredients (chicken, for example) at three different prices. The user should also be able to choose between three different bread types. Use CheckBoxes for additional ingredients - lettuce, tomato, etc.
Create an ArrayList to hold all of the sandwiches associated with an order. Display information about all the sandwiches that were ordered.

// Class SandwichShop definition

public class SandwichShop

{

// Creates a string array for sandwich ingredients  

String sandwichIngredients [] = {"Chicken", "Mutton", "Veg"};

// Creates a string array for bread types

String breadTypes[] = {"Bloomer", "Cob", "Plait"};

// Container object declared

// Component object declared

JList ingredient, bread;

JLabel ingL, breadL, amountL;

// Set the main panel layout to 4 rows and 1 column

mainP.setLayout(new GridLayout(4, 1));

// Adds main panel to frame

jf.add(mainP);

// Sets the frame visible property to true

jf.setVisible(true);

// Set the size of the frame to width 400 and height 150

// Registers action listener to exit button using anonymous class

// Checks if ingredient index is 1 and bread index is 2

// then set the amount 210 in text field

if(indexIngredient == 1 && indexBread == 2)

amountT.setText("210");

// Checks if ingredient index is 2 and bread index is 0

// then set the amount 97 in text field

if(indexIngredient == 2 && indexBread == 0)

amountT.setText("97");

// Checks if ingredient index is 2 and bread index is 1

// then set the amount 85 in text field

if(indexIngredient == 2 && indexBread == 1)

amountT.setText("85");

// Checks if ingredient index is 2 and bread index is 2

// then set the amount 70 in text field

if(indexIngredient == 2 && indexBread == 2)

amountT.setText("70");

}// End of method

});// End of anonymous class

}// End of default constructor

// main function definition

public static void main(String[] args)

{

// Creates an anonymous object by calling default constructor
