1. Create a Frame with Size 400x400 Using Swing
import javax.swing.JFrame;
public class SimpleFrame {
public static void main(String[] args) {
JFrame frame = new JFrame("400x400 Frame");
frame.setSize(400, 400); // Set frame size
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true); // Show the frame
}
}
2. Demonstrate Menu Implementation in a Frame Using Swing
import javax.swing.*;
public class MenuDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("Menu Example");
JMenuBar menuBar = new JMenuBar();
JMenu fileMenu = new JMenu("File");
JMenuItem openItem = new JMenuItem("Open");
JMenuItem saveItem = new JMenuItem("Save");
JMenuItem exitItem = new JMenuItem("Exit");
fileMenu.add(openItem);
fileMenu.add(saveItem);
fileMenu.addSeparator(); // Separator between items
fileMenu.add(exitItem);
menuBar.add(fileMenu); // Adding file menu to menu bar
frame.setJMenuBar(menuBar); // Set menu bar to frame
frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
3. Demonstrate Color and Shape with Color Filled Inside Using Swing
import javax.swing.*;
import java.awt.*;
public class ShapeColorDemo extends JPanel {
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.setColor(Color.RED);
g.fillRect(50, 50, 100, 100); // Filled rectangle
g.setColor(Color.GREEN);
g.fillOval(200, 50, 100, 100); // Filled oval
}
public static void main(String[] args) {
JFrame frame = new JFrame("Shapes and Colors");
frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new ShapeColorDemo());
frame.setVisible(true);
}
}
4. Program to List All Available Font Families
import java.awt.GraphicsEnvironment;
public class ListFonts {
public static void main(String[] args) {
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] fonts = ge.getAvailableFontFamilyNames();
System.out.println("Available Font Families:");
for (String font : fonts) {
System.out.println(font);
}
}
}
5. Implementation of FlowLayout
import javax.swing.*;
import java.awt.*;
public class FlowLayoutDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("FlowLayout Example");
frame.setLayout(new FlowLayout());
for (int i = 1; i <= 5; i++) {
frame.add(new JButton("Button " + i)); // Add buttons in FlowLayout
}
frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
6. Implementation of BorderLayout
import javax.swing.*;
import java.awt.*;
public class BorderLayoutDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("BorderLayout Example");
frame.setLayout(new BorderLayout());
frame.add(new JButton("North"), BorderLayout.NORTH);
frame.add(new JButton("South"), BorderLayout.SOUTH);
frame.add(new JButton("East"), BorderLayout.EAST);
frame.add(new JButton("West"), BorderLayout.WEST);
frame.add(new JButton("Center"), BorderLayout.CENTER);
frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
7. Swing Program to Show Implementation of Adapter Class
import javax.swing.*;
import java.awt.event.*;
public class AdapterDemo extends JFrame {
public AdapterDemo() {
addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
JOptionPane.showMessageDialog(null, "Mouse clicked at: " + e.getX() + ", " + e.getY());
}
});
setSize(400, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
public static void main(String[] args) {
new AdapterDemo();
