Design an application for the Sublime Sandwich Shop. The user makes sandwich order choices from list boxes, and the application displays the price. The user can choose from three main sandwich ingredients: chicken at $6. 99, beef at $7. 99, tuna at $8. 99. The user also can choose from three different bread types: white, rye, whole wheat at no change in cost

Sagot :

import java.awt.*;

import java.awt.event.*;

public class JSandwich extends JFrame implements ItemListener {

 FlowLayout flow = new FlowLayout();

 JLabel companyName = new JLabel("Sublime Sandwich");

 JComboBox<String> mainBox = new JComboBox<String>();

 JLabel mainList = new JLabel("Main ingredient");

 JComboBox<String> breadBox = new JComboBox<String>();

 JLabel breadList = new JLabel("Breads");

 JTextField totPrice = new JTextField(10);
