Fit Image to Screen

Question

I am using this code to make a screen saver that fades an image in then fades to another image. I would like to be able to set those images to full screen in case they are to large or to small for the current screen resolution. Any suggestions?
Thanks
class ScreenSaver {
public static void main(String[] args){
Saver s = new Saver();
s.sleepy();
class Saver extends JWindow implements MouseListener
Image i1;
Image i2;
Image i3;
Image i4;
Image i5;
Vector images = new Vector();
boolean first;
JPanel panel;
private static Thread t;
static float j = 1.0f;
BufferedImage bi;
Image img;
BufferedImage dest;
int i = 0;
int b = 1;
Saver(){
panel = new JPanel();
panel.addMouseListener(this);
getContentPane().add(panel);
setSize(getToolkit().getScreenSize());
ImageIcon ii1 =
new ImageIcon("1.jpg");
ImageIcon ii2 =
new ImageIcon("3.jpg");
ImageIcon ii3 =
new ImageIcon("4.jpg");
ImageIcon ii4 =
new ImageIcon("5.jpg");
ImageIcon ii5 =
new ImageIcon("6.jpg");
i1 = ii1.getImage();
i2 = ii2.getImage();
i3 = ii3.getImage();
i4 = ii4.getImage();
i5 = ii5.getImage();
images.addElement(i1);
images.addElement(i2);
images.addElement(i3);
images.addElement(i4);
images.addElement(i5);
dest = new BufferedImage(1000, 1000, BufferedImage.TYPE_INT_ARGB);
setVisible(true);
public void mouseClicked(MouseEvent e) {System.exit(0);}
public void mouseExited(MouseEvent e) {}
public void mouseEntered(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void paint(Graphics g) {
Graphics2D g2d = (Graphics2D)g;
Graphics2D destG = dest.createGraphics();
destG.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC, j));
destG.drawImage((Image)images.get(i),0,0,panel);
destG.setComposite(AlphaComposite.getInstance(AlphaComposite.XOR, 1.0f-j));
destG.drawImage((Image)images.get(b),0,0,panel);
g2d.drawImage(dest,0,0,panel);
public void sleepy() {
TimerTask task = new TimerTask() {
public void run() {
j = j - 0.01f;
if(j<0.02f) {
i++;
b++;
j=1.0f;
if(b>4) { b=0; }
if(i>4) { i=0; }
repaint();
Timer timer = new Timer();
timer.schedule(task, 0 , 4);

Basically what the last reply said. You have to add a couple 'getHeight' and 'getWidth' methods too. Also, to create your images, use a "factory method" (see 'createImage').
