Question

The program given here will draw the Olympic logo. Modify the program as the following:

1.Change the class name to Test1OlympicYourFirstNameYourLastName

2.Change the OlympicRingPanel class name to OlympicRingPanelYourfirstNameYourLastName

3.Modify the program so that the first ring will be filled with random color with a random alpha value. I have shown 3 sample output here for your references.
4.Modify the paintComponent so your name will be displayed under the Olympic rings.The color of your name should be random color as well.

this is for Java.............

first one:

// OlympicRingPanel.java
// program source: https://gist.github.com/jimmykurian/1732923

import javax.swing.JComponent;
import java.awt.*;
public class OlympicRingPanel extends JComponent
{
   public void paintComponent(Graphics g)
   {
     Graphics2D g2 = (Graphics2D) g;

   g.drawOval (1,0,40,40);
   g.setColor(Color.YELLOW);

   g.drawOval (21,20,40,40);
   g.setColor(Color.BLACK);

   g.drawOval (41,0,40,40);
   g.setColor(Color.GREEN);

   g.drawOval (61,20,40,40);
   g.setColor(Color.RED);

   g.drawOval (81,0,40,40);
   g.setColor(Color.BLUE);
   }
}

second one:

//OlympicRingViewer.java
// program source: https://gist.github.com/jimmykurian/1732923

import javax.swing.*;

public class OlympicRingViewer
{
   public static void main(String[] args)
   {
      JFrame frame = new JFrame();

      final int FRAME_WIDTH = 300;
      final int FRAME_HEIGHT = 230;

      frame.setSize(300, 230);
      frame.setTitle("OlympicRingViewer");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

      OlympicRingPanel component = new OlympicRingPanel();
      frame.add(component);

      frame.setVisible(true);
}
}

import javax.swing.JFrame;

class OlympicRingPanelYourName extends JComponent {
   public void paintComponent(Graphics g) {
       Graphics2D g2 = (Graphics2D) g;
       Random r = new Random();
       // filling the random color
       g.setColor(new Color(r.nextInt(255), r.nextInt(255), r.nextInt(255)));
       g.fillOval(1, 0, 40, 40);
       g.setColor(Color.YELLOW);

       g.drawOval(21, 20, 40, 40);

       g.drawOval(41, 0, 40, 40);
       g.setColor(Color.GREEN);

       g.drawOval(61, 20, 40, 40);
       g.setColor(Color.RED);

       g.drawOval(81, 0, 40, 40);
       g.setColor(Color.BLUE);
       // displaying the name
       g.drawString("Your Name", 80, 80);
   }
}

// OlympicRingViewer.java
// program source: https://gist.github.com/jimmykurian/1732923

public class Test1OlympicYourName {
   public static void main(String[] args) {
       JFrame frame = new JFrame();

       final int FRAME_WIDTH = 300;
       final int FRAME_HEIGHT = 230;

       frame.setSize(300, 230);
       frame.setTitle("OlympicRingViewer");
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       OlympicRingPanelYourName component = new OlympicRingPanelYourName();
       frame.add(component);

       frame.setVisible(true);
   }
}

Note: Replace the Test with Your Name with your actual name
