How to add a background image in Java and add a background image in Java

First, import the related packages:

Import java. awt. BorderLayout;

Import java. awt. Container;

Import javax. swing. ImageIcon;

Import javax. swing. JFrame;

Import javax. swing. JLabel;

Import javax. swing. JPanel;

You can also use:

Import java. awt .*;

Import javax. swing .*;

Create a Java form object and set it to visible

Eg: JFram frame = JFrame (); // create a form
Frame. setVisible (true); // sets the visible form, which is invisible by default.

Finally, write the following code:

/*
* The following seven lines Add a background image to the form:
*/
ImageIcon img = new ImageIcon ("E: \ 1" + ". gif"); // This is the background image.
JLabel imgLabel = new JLabel (img); // place the background image in the label.
Frame. getLayeredPane (). add (imgLabel, new Integer (Integer. MIN_VALUE); // note that this is the key. add the background tag to the LayeredPane panel of jfram.
ImgLabel. setBounds (, img. getIconWidth (), img. getIconHeight (); // you can specify the position of the background tag.
Container cp = frame. getContentPane ();
Cp. setLayout (new BorderLayout ());
(JPanel) cp). setOpaque (false); // note that the content panel is transparent. In this way, the background in the LayeredPane Panel can be displayed.

Write a try !!!

The complete code is as follows:

Container cp = frame. getContentPane ();

Cp. setLayout (new BorderLayout ());

}

Public MyFirstFrame (){

SetBounds (100,100,315,320); // you can specify the position and size of the displayed form.

System. out. println (getForeground ());

GetContentPane (). setLayout (null); // set to no layout manager
