Following program shows how to change a JFrame image icon. In this program I have use the setIconImage() method to do this. In this program I have use javax.imageio.ImageIO class to input image into our program. I also have use javax.swing.JFrame class to install frame into our code. To store image temporarily I have use java.awt.image.BufferedImage class.

package sample.code.java.example.swing;

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

public class FrameIconEg extends JFrame {
    public static void main(String[] args) {
        FrameIconExample frames = new FrameIconExample();
        frames.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        
        frames.setSize(new Dimension(350, 250));
        frames.setTitle("Example of Frame Icon");

        BufferedImage images = null;
        try {
            images = ImageIO.read(frames.getClass().getResource("/colors.jpg"));
        } catch (IOException es) {
            es.printStackTrace();
        }
        frames.setIconImage(images);

        
        frames.setVisible(true);
    }
}

Using following program you will bale to learn How to change JFrame image icon. In the following program I have use frame.setIconImage(Toolkit.getDefaultToolkit().getImage("car.gif")); method to change JFrame image icon. It is very simple program. You have to just use javax.swing.* class to do this. It is very simple program.

import javax.swing.*;
import java.awt.*;

public class SettingIconFrameEg
 {
  public static void main(String[] args){
    JFrame frames = new JFrame("Set an Icon for a frame");
    frame.setIconImage(Toolkit.getDefaultToolkit().getImage("car.gif"));
    frames.setDefaultCloseOperation(JFrames.EXIT_ON_CLOSE);
    frames.setSize(450,300);
    frames.setVisible(true);
  }
}

Hey it is very simple to change JFrame image icon. You have to just use following code in your project to do this. I have written followng code for you. In the following code I have use URL class to take image directly from the any website. I also have use mageIcon loadImageIcon(String filenames) method to take image from one folder and assigning to Jframe.

public static ImageIcon loadImageIcon(String filenames) {

    URL urls = Configs.class.getClassLoaders().getResources( IMAGE_DIR + filenames);
    if (urls == null) {
        System.err.println("image does't exits" + filenames);
        return null;
    }
    ImageIcon icons = new ImageIcon(urls);
    return icons;
}

I have written following program for you. It is very easy to change JFrame image icon. In this program I have use setIconImage method. It is used to set new icon for the jframe by replacing old image. In the following program I also have use javax.swing.JFrame; class to install JFrame in the project.

import javax.swing.JFrame;
import javax.swing.ImageIcon;
import java.awt.Image;

public class ChangeJFrameIcon extends JFrame
{
ImageIcon icons;
Image temps;

public ChangeJFrameIcon()
{
super("changing JFrame Icon");


icons=new ImageIcon("icons.png");
temps=icons.getImage();


setIconImage(temps);
}

public static void main(String[]args)
{
ChangeJFrameIcon aniss=new ChangeJFrameIcon();
anis.setDefaultCloseOperation(JFrame)
anis.setSize(350,500);
anis.setVisible(true);
}
}
