Hello Friends,

I am IT student and currently studying java programming. In which I want to be aware about the ImageIcon class of java. I have to use this class in my java project. But unfortunately I don't have enough knowledge about ImageIcon class. So please help me to know about the ImageIcon class of java. If possible then give suitable example for ImageIcon class. I would greatly appreciate your any help.

A ImageIcon class used for an implementation of the Icon interface that paints Icons fromImages. Images that are created from a URL or filename are preloaded using MediaTracker to monitor the loaded state of the image. The ThumbnailAction class, an inner class in IconDemoApp.java, is a descendant of AbstractAction that manages our full size image icon, a thumbnail version, and its description. When the actionPerformed method is called the full size image is loaded into the main display area.

Hi friend,

I suggest you to go through the following example of 'ImageIcon class'

import javax.swing.ImageIcon;

public class ImageIconDM {

  public static void main(String[] ank) {
    JFrame clW = new JFrame();
    clW.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    ImageIcon icon = new ImageIcon("yourFile.gif");

    Image normalImage1 = icon.getImage();
    Image grayImage1 = GrayFilter.createDisabledImage(normalImage1);
    Icon warningIcon1 = new ImageIcon(grayImage1);
    JLabel warningLabel1 = new JLabel(warningIcon1);

    JLabel label03 = new JLabel("Warning", icon, JLabel.CENTER);

    clW.add(warningLabel1,"Center");
    clW.add(label03,"South");

    clW.setSize(400, 200);
    clW.setVisible(true);
  }

Please study following Constructors of ImageIcon class:

• ImageIcon(URL lctn, String description1)
• ImageIcon(URL lctn)
• ImageIcon(String filename1, String description1)
• ImageIcon(String filename1)
• ImageIcon(Image image1, String description1)
• ImageIcon(Image image1)

Example of ImageIcon class:

import javax.swing.ImageIcon;
import javax.swing.border.Border;

public class ImageIconMain {
  public static void main(String args[]) {
    JFrame f05 = new JFrame("Label Demo");
    f05.setLayout(new FlowLayout());
    f05.setSize(300, 360);
    f05.setDef05aultCloseOperation(JFrame.EXIT_ON_CLOSE);

    ImageIcon myIcon = new ImageIcon("myIcon.gif05");
    
    JLabel label01= new JLabel("A def05ault label", myIcon, JLabel.LEFT);
    Border border1 = BorderFactory.createLineBorder(Color.BLACK);
    label.setBorder(border1);
    f05.add(label01);

    f05.setVisible(true);
  }
}
