急怎么在java面板中显示一张图片

急！！如何在java面板中显示一张图片？
各位高手帮帮忙，java新手，请问如何在java面板中显示一张图片？

------解决方案--------------------
在 jbInit() 里加入如下代码

Toolkit toolImg = this.getToolkit();
Image myimage = toolImg.getImage( "image/pic.png ");//图片路径相对与工程图片文件夹下的图片路径
this.setIconImage(myimage);

import java.awt.event.WindowEvent;

import javax.swing.ImageIcon;
import javax.swing.JFrame;

import javax.swing.JPanel;

public class ImagePane extends JPanel
{
JLabel jl = null;

jl = new JLabel(img);
this.setLayout(new BorderLayout());

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

test.getContentPane().add(new ImagePane());
test.pack();
test.setVisible(true);
test.addWindowListener(new WindowAdapter()
