这个项目是课程设计的时候随手写的，没有去考虑过规范效率优美这些东西，但是还是写出来记录一下吧。说不定能给某个看到的人一点思路。

package dn.dmandp.maingui;

import java.awt.Dimension;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.SwingConstants;

public class ImagicLabel extends JLabel{
	private static final long serialVersionUID = 1L;
	ImagicLabel(ImageIcon icon){
		setPreferredSize(new Dimension(100,100));
		setSize(100,100);
		setIcon(icon);
		setHorizontalAlignment(SwingConstants.CENTER);
	}
}

上面这个类没什么特殊意义，就是用来方便初始化的时候传图片。

下面是主类：

package dn.dmandp.maingui;

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import java.awt.event.MouseEvent;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

具体也没什么好说的，感觉已经注释的差不多了。就是放九个标签，每个标签一张图。点击空白图四周的标签就可以跟空白图交换~就这样吧233
