Trying to use a Buffered Image any help

Question

I have write the program but cant see what the problem is. My compiler being "blueJ" says cannot resolve symbol- method getImage().
Image has been defined so what is wrong with it, id be grateful for a solution..
My code is as folows.......
import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
public class ImageBuffered extends Applet
private final int RIGHT = 1, LEFT = -1;
private int x, y, w, h;
private Graphics g;
private int dir = RIGHT;
private Image offscreenImage;
public void init()
addMouseListener( new MouseHandler( this ) );
w = getWidth();
h = getHeight();
x = 20;
y = h / 2;
public void start()
g = getGraphics(); paint( g );
public void paint( Graphics g)
Image offscreenImage = getImage();
if( ( offscreenImage == null ) || ( offscreenImage.getHeight( this ) != h ) || ( offscreenImage.getWidth( this ) != w ) )
offscreenImage = createImage( w, h );
setImage( offscreenImage );
g.drawImage( getImage(), 0, 0, this );
class MouseHandler extends MouseAdapter
private Applet applet;
public MouseHandler( Applet a )
applet = a;
public void mouseClicked( MouseEvent e ) {
w = getWidth();
h = getHeight();
Image offscreenImage = getImage();
if ( ( offscreenImage == null ) || ( offscreenImage.getHeight(applet) != h ) || ( offscreenImage.getWidth( applet ) != w ) )
offscreenImage = createImage( w, h ); setImage(offscreenImage );
Graphics ig = getImage().getGraphics();
for( int i = 0; i < 400; i++ )
ig.clearRect( 0, 0, w, h );
ig.setColor( Color.red );
ig.fillRect( x, y, 20, 10 );
ig.setColor( Color.green );
ig.fillRect( x + 20, y + 20, 20, 10 );
paint( g );
x += dir;
try
Thread.sleep( 1 );
catch( InterruptedException ie ){}
if( dir == RIGHT )
dir = LEFT;
else
dir = RIGHT;
Thankyou for your time........

You're already calling it in 4 places in your code, aren't you? Where did you expect it to be? Is this code you copied from someplace?
