怎样实现在java中点击jbutton改变一个jlabel的位置？

import java.awt.event.*;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class GUI {
private static JFrame frame = new JFrame("GUI test");
private static JPanel panel = new JPanel();

private static JButton button = new JButton("Button1");;
private static ImageIcon imageIcon = new ImageIcon("F:\\BluetoothChat\\a5_16.png");
private static JLabel label = new JLabel(imageIcon);
public static void main(String[] args) {
frame.setLayout(null);
panel.setLayout(null);
label.setLayout(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(500, 500);
panel.add(button);
// button.setLocation(100, 100);
button.setBounds(150, 150, 150, 150);
panel.add(label);
label.setBounds(50,50,100,100);
panel.setBounds(0, 0, 300, 300);
frame.add(panel);
frame.setVisible(true);
}

}
这里是我的代码，运行后是一个button和一张图，怎样给button添加单击事件改变这张图的位置？

Answer 1

button.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
         label.setBounds(150,150,50,50);
         panel.revalidate();
         panel.repatin();  
    }   
});
