Help me with my wierd applet please.

(I'm not even close to being sure that this is even a valid approach to what I want to accomplish. Still, all input is welcome. What I was trying to do was create an applet that reads):


"Please pass the butter."
A quote by jack padron
-------------------------------------------
Can you think of a better quote?
Please, write it here.


(then, of course the user writes his or her quote. After that, my program would print):


Please write the author of the quote here.


(After entering the author, it would print the quote that the user wrote and the author underneath.I coded it perfectly as a regular java program that was unappletatized. Then I wanted to put it all into applet form... This is where I'm sure I messed up. My new weird Applet program [a modified version of the original non-applet program] doesn't work. (The original was all System.out.println(); not page.draw) I'm sure that it's laced with mistakes, but there is only one runtime error and it is the classic"java.lang.NoSuchMethodError: mainException in thread "main" ")

(Here is my program)
Java Syntax (Toggle Plain Text) 
  1. <span class="ad_notxt"><code class="inlinecode">
  2.  
  3. import java.applet.Applet;
  4. import java.awt.*;
  5. import java.util.Scanner;
  6.  
  7. public class Quote extends Applet 
  8. {
  9.  
  10. 	public void paint(Graphics page)
  11.  
  12.     	{
  13.  
  14.     		String theirQuote; 
  15.  
  16.     		String theAuthor;
  17.  
  18.     		Scanner scan = new Scanner(System.in); 
  19.  
  20.     		page.drawString ("\"Please pass the butter.\"", 110, 70);
  21.  
  22.     		page.drawString ("A quote by jack padron", 110, 70);
  23.  
  24.     		page.drawString ("-------------------------------------------", 110, 70);
  25.  
  26.     		page.drawString ("Can you think of a better quote?", 110, 70);
  27.  
  28.     		page.drawString ("Please, write it here.", 110, 70);
  29.     		theirQuote = scan.nextLine();
  30.  
  31.     		page.drawString ("Please write the author of the quote here.", 110, 70); 
  32.     		theAuthor = scan.nextLine();
  33.  
  34.     		page.drawString ("-------------------------------------------", 110, 70);
  35.  
  36.     		page.drawString ("Tadaaaa!!! This is the quote you entered.", 110, 70);
  37.  
  38.     		page.drawString ("...and the author :)", 110, 70);
  39.  
  40.     		page.drawString (theirQuote, 110, 70);
  41.  
  42.     		page.drawString ("         -" + theAuthor, 110, 70);
  43.     }
  44.  
  45.  
  46. }
  47. </code></span>

If you have any questions about what I was trying to explain, just ask, of course.
