How to Resize an Image in Swing?

Question

I've learnt how to add an image in Javax swing a lot of times. I've used containers and all imageicons, however the problem is that my photos are too large to fit in. They are above 1800*1700 pixels in size and the screen obviously can't accomodate them. I would request you guys to suggest a way to scale the image down. Just FYI, I've tried most of these methods like using awt Image, setBounds, SCALE_DEFAULT and stuff. For some reason, my IDE, BlueJ doesn't seem to work with a lot of the methods which are suggested, still I would request you to please help me. Here is the code:

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


class JLabelDemo
{
public JLabelDemo()
{
    JFrame jfrm=new JFrame("Image from book");
    jfrm.setLayout(new FlowLayout());
    jfrm.setDefaultCloseOperation(jfrm.EXIT_ON_CLOSE);
    jfrm.setSize(500,700);
    
    ImageIcon ii=new ImageIcon("D:\\Dhruv Rana\\UNATIS Mandarmoni Trip\\Sunrise.jpg");
    JLabel jl=new JLabel("Background",ii,JLabel.CENTER);
    jfrm.add(jl);
    jfrm.setVisible(true);
}
public static void main(String [] args)
{
    SwingUtilities.invokeLater(
    new Runnable()
    {
        public void run()
        {
            new JLabelDemo();
        }
    }
    );
}
}

put it in an bufferedImage

Graphics2D grph = image.createGraphics();
grph.scale(2.0, 2.0);
grph.dispose();
