尝试使用url类和url.openstream（）从url读取文件。
代码：

try {
                   URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
                   Scanner s = new Scanner(url.openStream());
                   // read from your scanner
                }
                catch(IOException ex) {
                   // there was some connection problem, or the file did not exist on the server,
                   // or your URL was not in the right format.
                   // think about what to do now, and put it here.
                   ex.printStackTrace(); // for now, simply output it.
                }

我得到一个错误：openstream iusundefined for the docflavor.url方法。
我尝试的是：
ide建议更改我所做的转换，结果是：

URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
                   Scanner s = new Scanner(((Object) url).openStream());
                   // read from your scanner

仍然是相同的错误。我还尝试将对象更改为url:

URL url = new URL("http://www.puzzlers.org/pub/wordlists/pocket.txt");
                   Scanner s = new Scanner(((URL) url).openStream());
                   // read from your scanner

请帮忙谢谢！
