[java] How to set an image as a background for Frame in Swing GUI of java?

I have created one GUI using Swing of Java. I have to now set one sample.jpeg image as a background to the frame on which I have put my components.How to do that ?

The Background Panel entry shows a couple of different ways depending on your requirements.

You can either make a subclass of the component

Or fiddle with wrappers

Perhaps the easiest way would be to add an image, scale it, and set it to the JFrame/JPanel (in my case JPanel) but remember to "add" it to the container only after you've added the other children components.

    ImageIcon background=new ImageIcon("D:\\FeedbackSystem\\src\\images\\background.jpg");
    Image img=background.getImage();
    Image temp=img.getScaledInstance(500,600,Image.SCALE_SMOOTH);
    background=new ImageIcon(temp);
    JLabel back=new JLabel(background);
    back.setLayout(null);
    back.setBounds(0,0,500,600);

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class BackgroundImageJFrame extends JFrame
{
  JButton b1;
  JLabel l1;
public BackgroundImageJFrame()
{
setTitle("Background Color for JFrame");
setSize(400,400);
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
/*
 One way
-----------------*/
setLayout(new BorderLayout());
JLabel background=new JLabel(new ImageIcon("C:\\Users\\Computer\\Downloads\\colorful design.png"));
add(background);
background.setLayout(new FlowLayout());
l1=new JLabel("Here is a button");
b1=new JButton("I am a button");
background.add(l1);
background.add(b1);

// Another way
setLayout(new BorderLayout());
setContentPane(new JLabel(new ImageIcon("C:\\Users\\Computer\\Downloads  \\colorful design.png")));
setLayout(new FlowLayout());
l1=new JLabel("Here is a button");
b1=new JButton("I am a button");
add(l1);
add(b1);
// Just for refresh :) Not optional!
  setSize(399,399);
   setSize(400,400);
   }
   public static void main(String args[])
  {
   new BackgroundImageJFrame();
 }
 }

Here is another quick approach without using additional panel.

JFrame f = new JFrame("stackoverflow") { 
  private Image backgroundImage = ImageIO.read(new File("background.jpg"));
  public void paint( Graphics g ) { 
    super.paint(g);
    g.drawImage(backgroundImage, 0, 0, null);
  }
};

This is easily done by replacing the frame's content pane with a JPanel which draws your image:

try {
    final Image backgroundImage = javax.imageio.ImageIO.read(new File(...));
    setContentPane(new JPanel(new BorderLayout()) {
        @Override public void paintComponent(Graphics g) {
            g.drawImage(backgroundImage, 0, 0, null);
        }
    });
} catch (IOException e) {
    throw new RuntimeException(e);
}

This example also sets the panel's layout to BorderLayout to match the default content pane layout.

(If you have any trouble seeing the image, you might need to call setOpaque(false) on some other components so that you can see through to the background.)

if you are using netbeans you can add a jlabel to the frame and through properties change its icon to your image and remove the text. then move the jlabel to the bottom of the Jframe or any content pane through navigator
