new file 读取问题：报错

http格式获取的是io流吧，是不是先请求这个http获取到数据流 在转换为文件

String fileUrl = "http://pic44.nipic.com/20140723/18505720_094503373000_2.jpg";
        try {
            URL url = new URL(fileUrl);
            URLConnection urlConnection = url.openConnection();
            HttpURLConnection httpURLConnection = (HttpURLConnection) urlConnection;
            //设置超时
            httpURLConnection.setConnectTimeout(30000);
            //设置请求方式，默认是GET
            httpURLConnection.setRequestMethod("GET");
            //设置字符编码
            httpURLConnection.setRequestProperty("Charset", "UTF-8");
            //打开到此 URL引用的资源的通信链接（如果尚未建立这样的连接）。
            httpURLConnection.connect();
            //建立链接从请求中获取数据
            BufferedInputStream bin = new BufferedInputStream(httpURLConnection.getInputStream());
            File file = new File("F:\\photos\\测试.jpg");
            OutputStream out = new FileOutputStream(file);
            int size = 0;
            int len = 0;
            byte[] buf = new byte[2048];
            while ((size = bin.read(buf)) != -1) {
                len += size;
                out.write(buf, 0, size);
            }
            // 关闭资源
            bin.close();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

不知道你的需求是不是这样的
