Image not showing on the window

I have reduced my codes to such a simple function: to show a picture on a window. But why does the picture not show up however I tried? I create a JFrame, and then created a JPanel which is expected to show the picture. Then add the panel to the frame. By the way, I imported the picture and double clicked it to get the url.

import java.awt.*;

import javax.swing.*;

import com.sun.prism.Graphics;

public class GUI {
    JFrame frame=new JFrame("My game");
    JPanel gamePanel=new JPanel();

    public static void main(String[] args){
        GUI gui=new GUI();
        gui.go();
    }

    public void go(){

        frame.setSize(300, 400);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        Background backPic=new Background();
        backPic.setVisible(true);
        frame.getContentPane().add(backPic);        

        JPanel contentPane=(JPanel) frame.getContentPane();
        contentPane.setOpaque(false);

        frame.setVisible(true);
        }

    class Background extends JPanel{
            public void paintComponent(Graphics g){
                ImageIcon backgroundIcon=new         ImageIcon("file:///E:/eclipse/EL/backgroundPicture.jpg");
                Image backgroundPic=backgroundIcon.getImage();

                Graphics2D g2D=(Graphics2D) g;
                g2D.drawImage(backgroundPic,0,0,this);
            }
        }
}

It's because you've imported com.sun.prism.Graphics. It should be java.awt.Graphics.

I would also get rid of the "file:///" bit from your path. And you also probably don't want to be loading the image on each paint event. Here's a better version of the Background class;-

class Background extends JPanel {

    Image backgroundPic;

    public Background() {
        ImageIcon backgroundIcon=new ImageIcon("E:/eclipse/EL/backgroundPicture.jpg");
        backgroundPic=backgroundIcon.getImage();
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2D=(Graphics2D) g;
        g2D.drawImage(backgroundPic,10,10,this);
    }
}
