![## MyFrame Demo
The image demonstrates a simple Java Swing application named "MyFrame Demo." At the top of the application window, there are three buttons labeled "Left," "Middle," and "Right." Below is the Java code snippet that creates a GUI similar to what is shown in the image.
### Code Explanation:
```java
// Implement Java code in the constructor of MyFrame below to create a GUI like the image above.
// No event listeners and handlers are required.
class MyFrame extends JFrame {
private JButton[] buttons;
public MyFrame() {
super("MyFrame Demo");
// Add the implementation for the GUI here
}
}
```
### Detailed Code Breakdown:
- **Class Declaration:**
- The class `MyFrame` extends `JFrame`, indicating it is a frame/window in a Swing application.
- **Private Member:**
- `private JButton[] buttons;` is declared but not initialized. This will store the array of buttons.
- **Constructor:**
- The constructor `MyFrame()` calls the superclass constructor with the title "MyFrame Demo".
- Placeholders are given for adding the necessary GUI implementation to match the image above.
### Creating the GUI:
To create the GUI as shown in the image, you would need to:
1. Initialize the `buttons` array with three `JButton` components.
2. Set the layout of the frame, likely using a `FlowLayout` to align the buttons horizontally.
3. Add the buttons to the frame.
Here is a potential implementation:
```java
import javax.swing.*;
public class MyFrame extends JFrame {
private JButton[] buttons;
public MyFrame() {
super("MyFrame Demo");
buttons = new JButton[3];
buttons[0] = new JButton("Left");
buttons[1] = new JButton("Middle");
buttons[2] = new JButton("Right");
setLayout(new FlowLayout());
for (JButton button : buttons) {
add(button);
}
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(300, 100);
setVisible(true);
}
public static void main(String[] args) {
new MyFrame();
}
}
```
### Explanation of Implementation:
1. **Initialization:**
- Create three `JButton` instances labeled "Left," "Middle," and "Right."
2. **Layout Setting:**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F03256047-c4d6-4acb-b3bb-18185f2c131a%2F5908976b-914d-4664-bd25-a5cf6230623d%2F729s9y8_processed.png&w=3840&q=75)
