在JFame中重载paint方法显示图片

先上显示效果：

代码：

package com.hy;

import java.awt.Graphics;

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

public class ShowGui extends JFrame{
    
    public void paint(Graphics g){
        ImageIcon icon = new ImageIcon("c:/hy/2611.jpg");
        int iconWidth=icon.getIconWidth();
        int iconHeight=icon.getIconHeight();
        g.drawImage(icon.getImage(), (int) (this.getWidth() - iconWidth) / 2,
                (int) (this.getHeight() - iconHeight) / 2, iconWidth, iconHeight, null);
    }

}

End
