以JPanel为基础实现一个图相框

代码：

import java.awt.Graphics;

import javax.swing.ImageIcon;

import javax.swing.JPanel;
public class Picture extends JPanel {

    private static final long serialVersionUID = -4437881316229152596L;
private ImageIcon icon;
public Picture(java.net.URL imgURL) {

        icon = new ImageIcon(imgURL);

    }
public void paintComponent(Graphics g) {

        int x = 0, y = 0;
g.drawImage(icon.getImage(), x, y, getSize().width, getSize().height,

                this);
while (true) {

            g.drawImage(icon.getImage(), x, y, this);
if (x > getSize().width && y > getSize().height){

                break;

            }
if (x > getSize().width) {

                x = 0;

                y += icon.getIconHeight();

            } else{

                x += icon.getIconWidth();

            }

        }

    }

}

使用实例：

Picture picture=new Picture(getClass().getResource("/welcome.jpg"));

效果图：
