• Write a Java Program using GUI objects from Swing package.

Hardware/ Software : Personal Computer, Java Development Kit version X.x.x., NetBeans IDE 12.0

LAB ACTIVITY 2D

Question:

Create the interface below:

1. Setup the Development Environment

• Open your preferred Java IDE (e.g., NetBeans, IntelliJ IDEA, or Eclipse).

• Create a new Java project.

• Create a new Java class file, and name it LabAct3c.

2. Import Required Libraries

• At the beginning of your Java file, import the necessary libraries to use Swing and other Java components.

3. Create the Main Class

• Define the class LabAct3c that extends JFrame. This class will hold the main GUI components

4. Set Up GUI Components for Main Frame

• In the constructor of LabAct3c, set up the basic properties of the frame:

  • Define the close operation using setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);.

  • Use setLayout(new FlowLayout()); to set a layout for the main container.

  • Add panels for different sections like the title, order form, and total section.

  • Define the frame size and make it visible using setVisible(true);.

5. Create the Title Panel

• Create an inner class PanelTitle that extends JPanel.

• Set the layout for this panel (use FlowLayout for simple horizontal placement).

• Add a JLabel to display the title "BURGER ORDERING SYSTEM" in bold and larger font size

6. Create the Order Form Panel

• Create another inner class OrderForm that extends JPanel.

• Use GridBagLayout for a more structured layout, as this allows for easy alignment of labels, text fields, checkboxes, and combo boxes.

• Add components for:

  • Order Number: Label and Text Field.

  • Product Selection: Checkboxes for different burger types (Beef, Chicken, Combo).

  • Quantity: Text fields to input quantities for each burger type.

  • Additional Options: Combo boxes for additional toppings like "Cheddar Cheese" and "Parmesan Cheese."

  • Order Type: Radio buttons for selecting delivery or self-pickup.

  • Other Costs: A slider to indicate additional costs.

7. Create the Total Panel

• Define another inner class PanelTotal that extends JPanel.

• Set up a grid layout for this panel and add components for the total payment calculation.

• Add a text field that will eventually display the total price, but keep it disabled as it's only for display.

8. Compile and Run the Program

• After setting up the layout and components in each of the inner panels (PanelTitle, OrderForm, and PanelTotal), compile and run the program.

• This should display the GUI with all the components properly arranged.

9. Test the Interface

• Run the program and interact with the GUI.

• Although no functionality (event handling) is included, you should be able to see all the fields, buttons, checkboxes, radio buttons, combo boxes, and sliders.
