如上述代码 我想用个List 导入网址 到WebBrowserExample（url）中 然后new出多个网页的panel 
我在main函数里这么写

Java code

public static void main(String[] args) {        List<String> list =new ArrayList<String>();        list.add("www.baidu.com");        list.add("www.hao123.com");        for (int i = 0; i < list.size(); i++) {            new WebBrowserExample(list.get(i));            JFrame frame = new JFrame("DJ Native Swing Test");            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);            frame.add(new WebBrowserExample(list.get(i)), BorderLayout.CENTER);            // frame.setUndecorated(true);            // frame.setSize(1024, 768);            frame.setSize(800, 600);            // frame.setLocationByPlatform(true);            frame.setVisible(true);        }    }

如果list就一个值 就没问题 要是大于一个值就异常

请各位帮帮忙啊 很急 在线等到解决 因为是新手 所以最好能说清楚怎么写。 可以QQ联系我 99296428 说明来意 别忘了 在论坛里留个言 好给你们加分！！！

[解决办法]

Java code

我是想 new 出来N个不同的网页 全部显示 new WebBrowserExample(list.get(i));            JFrame frame = new JFrame("DJ Native Swing Test");            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);            frame.add(new WebBrowserExample(list.get(i)), BorderLayout.CENTER);
[解决办法]
加载多个页面，应该就是多线程了。
