Here's a 'stretch to fit' JFrame app
import java.awt.*;
import javax.swing.*;
public class JFrameImageFill extends JFrame {
  public JFrameImageFill() {
      Container c    = getContentPane();
      JPanel panel = new JPanel(){
             public void paintComponent(Graphics g)     {
                  ImageIcon img = new ImageIcon("add.jpg");
            ImageIcon bigImage = new ImageIcon(img.getImage().getScaledInstance
                               (getWidth(), getHeight(),Image.SCALE_REPLICATE));
            g.drawImage(bigImage.getImage(), 0, 0, this);
                  super.paintComponent(g);
        panel.setOpaque(false);
      c.add(panel);
  public static void main(String[] args) {
    JFrameImageFill frame = new JFrameImageFill();
    frame.setSize(200,200);
    frame.setVisible(true);
}Setting the colour of the JPanelimport java.awt.*;
import javax.swing.*;
public class MyJFrame extends JFrame {
  public MyJFrame() {
      super("My first JFrame");
      Container c  = getContentPane();
      JPanel panel = new JPanel();
      panel.setBackground(Color.white);
//OR: panel.setBackground (new Color(255, 255, 255));     
//also works giving you a choice of the full 24-bit colour range
      c.add(panel);
  public static void main(String[] args) {
    MyJFrame frame = new MyJFrame();
    frame.setSize(200,200);
    frame.setLocation(200, 300);
    frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
    frame.setVisible(true);
}
