//放置图片

panel.add(imgLb1);
//如果未提供此图片将会有异常抛出
java.net.URL url = this.getClass().getResource("apples.gif");
Icon icon = new ImageIcon(url);
imgLb1.setIcon(icon);
这个地方如果写成这样就错了：
[color=#0000FF]URL url = this.getClass().getResource("apples.gif");
Icon icon = new ImageIcon(url);
imgLb1.setIcon(icon);[/color]
错误提示是：
Type mismatch: cannot convert from URL to DocFlavor.URL
以上是部分代码
这是为什么求赐教 谢谢！

import javax.print.DocFlavor.URL; 换成 import java.net.URL 你包引错了啊..
