package Animation;

import java.applet.*;
import java.awt.*;

// Defines class BannerText extends from super class Applet
// and implements Runnable interface
public class BannerText extends Applet implements Runnable
{
   // Assigns a string
   String message = "Pyari Mohan Sahu ";
   // Creates a font class object
   Font f = new Font("Arial", Font.BOLD, 25);
   // Creates a Thread class object
   Thread myThread;
  
   // Overrides init() method to set the background
   // color and applet size
   public void init()
   {
       setForeground(Color.BLUE);
       setSize(230, 200);
   }
  
   // Overrides start() method to create and start the thread
   public void start()
   {
       myThread = new Thread(this);
       myThread.start();
   }
  
   // Overrides run() method to move text
   public void run ()
   {
       char currentChar;
      
       // Loops infinite times
       for( ; ; )
       {
           try
           {
               // Calls the method to repaint() applet area
               repaint();
               // Sleeps for 2 second
               Thread.sleep(2000);
               // Extracts the character at 0th index position
               currentChar = message.charAt(0);
               // Extracts the sub string from 1st index position to last
               message = message.substring(1, message.length());
               // Concatenate the current character at the end of the message
               message += currentChar;
           }
           catch(InterruptedException e) {}
       }
   }
  
   // Overrides paint() method to display the text
   public void paint(Graphics g)
   {
       // Creates a rectangle
       g.fillRect(1,1,230,200);
       // Sets the color of the text to yellow
       g.setColor(Color.YELLOW);
       // Sets the font of the text
       g.setFont(f);
       // Displays the message
