B) Write an applet application to display Table lamp. The color of lamp should get change randomly.1. Open Notepad.
2. Type the following code:
-
import java.applet.Applet;
import java.awt.Color;
import java.awt.Graphics;
import java.util.Random;
public class TableLampApplet extends Applet implements Runnable {
private Color lampColor;
private Thread thread;
@Override
public void init() {
lampColor = Color.YELLOW; // Initial color
thread = new Thread(this);
thread.start();
}
@Override
public void paint(Graphics g) {
// Draw the table lamp base
g.setColor(Color.DARK_GRAY);
g.fillRect(90, 150, 20, 80); // base
// Draw the lamp shade with the current lamp color
g.setColor(lampColor);
g.fillOval(50, 50, 100, 100); // lamp shade
// Draw the lamp post
g.setColor(Color.GRAY);
g.fillRect(90, 130, 20, 20); // post
}
@Override
public void run() {
Random rand = new Random();
while (true) {
// Generate random color for the lamp
lampColor = new Color(rand.nextInt(256), rand.nextInt(256), rand.nextInt(256));
// Repaint the applet to reflect the new color
repaint();
try {
Thread.sleep(1000); // Change color every 1 second
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
4. Create an HTML file to run the applet. Save the following code in a file named TableLampApplet.html:
-
<html>
<body>
<applet code="TableLampApplet.class" width="400" height="200">
</applet>
</body>
</html>
6 Compile the Java program by typing:
javac TableLampApplet.java
7. Run the applet using an applet viewer or a compatible web browser. You can use the appletviewer tool that comes with the JDK to run the HTML file:
appletviewer TableLampApplet.html
