(2) Display Image in jLabel in Java Swing Dynamic way:

If you want to show image in dynamic way, you have to write code for it, Suppose you want to show picture during jFrame's open or activate. So write code as we describe bellow.

But first, you have to import some class inside your java Package:

package simple_java; 

  import java.awt.image.BufferedImage;
  import java.io.IOException;
  import javax.imageio.ImageIO;
  import javax.swing.ImageIcon;

Now lets write show picture code on WindowsOpened evets:

private void formWindowOpened(java.awt.event.WindowEvent evt) { 
   try{
       BufferedImage image1 = ImageIO.read(getClass().getResource("skotechlearn.png"));
       jLabel1.setIcon(new ImageIcon(image1));
   }catch(IOException imgl){}

 }

How to show external image in jLabel?

If you want to show picture from external url or path, then write code like:

String myimgpath; 
myimgpath= "your exteral file path";
Icon myimgicon = new ImageIcon(myimgpath);
jLabel1.setIcon(myimgicon);

When you run application then it will load picture during runtime and display it on jLabel.

Note:- You can also set jLabel as background image by setting the height width of jLabel according to jFrame.

So, this is the way of displaying image on jFrame in java Netbeans with static and dynamic process which is easily described in above given step by step process in SKOTechlearn post.
