[Java] First Steps: Load a PNG/JPG image in a JFrame

Hi, this is one simple code for load and show an image inside a JFrame, using a BufferedImage to load image data from a specific local path (could be a URL if you prefer).


Steps:
1.- Create a BufferedImage object.
2.- Read the image file for a specific path
3.- Draw the image in the screen using "paint()" method.

That's it!

package mx.gcross.samples;

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

public class MyWindow extends JFrame {

    //Object for image
    private BufferedImage background;

    public MyWindow() {

        setSize(480, 320); //set window dimension 480x320px
        loadImages();
        setVisible(true); //make window visible
    }

    public void loadImages() {
        try {
            //path for image file
            String path = "images/background.png"; 
            background = ImageIO.read(new File(path));
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        //draw the bufferedImage object
        g.drawImage(background, 0, 0, this); 
    }

    public static void main(String[] args) {
        new MyWindow();
    }
}

Test the code and comment, thanks!.
