Java MalformedURLException无法修复

Question

我正在解决我的代码中的问题，这个实验室会显示来自网址的图片，但不断收到输出：“哦，哦，发生了一些不好的事情。”来自catch块中的给定代码

我一直在寻找如何解决网址问题，我尝试重新输入双引号和http：//并在浏览器中运行网址没有任何问题。我似乎无法弄明白我从

获得例外的地方

文件名http://venus.cs.qc.cuny.edu/~aabreu/cs212/images/

这是调用URL的代码

public void loadImages() {
    Document doc;
    String url = "http://venus.cs.qc.cuny.edu/~aabreu/cs212/images/";
    int j = 0;
    try {
        System.out.println("Reading URL directory");
        doc = Jsoup.connect(url).get();
        Elements files = doc.getElementsByTag("a");
        // initialize the array size for the filenames
        picture = new String[files.size()];
        for (Element file : files) {
            String filename = file.attr("href");
            if (filename.indexOf(".jpg") >= 0 || filename.indexOf(".gif") >= 0) {
                System.out.println(filename);
                picture[j++] = url + filename;
            }
        }
    } catch (IOException ioe) {
        ioe.printStackTrace();
    }
}
