I am a novice java are learning java, encountered the following code book

import java.awt.Graphics;
  import java.applet.Applet;
  
  public class FriendlyDataTest extends Applet {
  	
  	private FriendlyData d;
  	
  	public void init(){
  		d = new FriendlyData();
  		
  	}
  	
  	public void paint(Graphics g){
  		
  		g.drawString("After instantiation: ",25,25);
  		g.drawString(d.toString(), 40, 40);
  
  		
  		
  		d.x = 77;
  		d.s = new String("Good bye");
  		g.drawString("After changing values: ", 25, 55);
  		g.drawString(d.toString(), 40, 70);
  		
  		
  		
  	}
  
  }
  
  class FriendlyData{
  	 int x;
  	 String s;
  	 
  	 public FriendlyData(){
  		 x = 0;
  		 s = new String("Hello");
  		 
  	 }
  	 
  	 public String toString(){
  		 return "x: "+x+"    s: "+s;
  	 }
  }
  

the results given in the book are : The first one shows x: 0 s: Hello
second display x: 77 s: Good bye

personal look at the code also think it should be the result, but the result of this code is run out Show All
x: 77 s: Good bye

someone can answer my doubts do next
Thank you ~ ~ ~
------ Solution -------------------------------- ------------
paint method should be called twice , RBI log into the console you look
------ Solution -------- ------------------------------------
run a bit

seeking specific method I use eclipse

seeking specific method I use eclipse  

paint line method Riga
System.out.println ("paint")
------ For reference only ------------------------ ---------------
to x, s added another run getter and setter methods .

------ For reference only ----- ----------------------------------
on the applet unfamiliar . . Temporarily unable to explain . .
------ For reference only -------------------------------------- -

seeking specific method I use eclipse          
  
paint line method Riga   
System.out.println ("paint")  
confirmed the next is called twice
Why is this so

The idea of this code is to achieve out of the friend access
you do not know now changed back principle ......

never engaged applet, why wasting energy on this . .

Why is it so  

generally created when the form is called a paint, you use the drawing api Shiyou call once, twice.

nothing to get to the bottom of this , after all, are the people designing the framework , as long as know what is going on the trip .

The private FriendlyData d; paint method as a variable into the body in just fine
