关于Java URL 获取图片路径问题， 具体路径怎么设置， 下小白求指教，源代码如下

package graphics.test;

import java.awt.Canvas;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.Toolkit;
import java.net.URL;

import javax.swing.JFrame;
import javax.swing.WindowConstants;

public class DrawImage extends JFrame
{
Image img;
public DrawImage()
{
URL u = DrawImage.class.getResource("img.jpg"); //获取图片资源路径
img = Toolkit.getDefaultToolkit().getImage(u); //获取图片资源
this.setSize(300, 300);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
add(new CanvasPanel());
this.setTitle("绘制图片");
}

class CanvasPanel extends Canvas
{
public void paint(Graphics g)
{
super.paint(g);
Graphics2D g2 = (Graphics2D) g;
g2.drawImage(img, 0, 0, this);
}
}

public static void main(String[] args)
{
new DrawImage().setVisible(true);
}
}
