我建议为您的 I/O 使用 try-with-resources 结构并查看 java 命名约定。如果要将 http-call 的输出写入文件，可以执行以下操作：

public static void main(String[] args) throws Exception {
  URL googleUrl = new URL("http://www.google.com/");
  try (BufferedReader in = new BufferedReader(new 
    InputStreamReader(googleUrl.openStream()));
    PrintWriter out = new PrintWriter(new FileWriter("path/to/desired/file"))) {
    String inputLine;
    while ((inputLine = in.readLine()) != null) {
      System.out.println(inputLine);
      out.println(inputLine);
    }
  }
  catch (Exception e) {
    System.out.println(e.getMessage());
  }
}
