我的主要问题是一些代码检索网页源代码,但缺少一些代码.例如,下面的代码对于第一个链接不起作用.

InputStream is = fURL.openStream(); //fURL can be one of the links above
BufferedReader buffer = null;
buffer = new BufferedReader(new InputStreamReader(is,"iso-8859-9"));

int byteRead;
while ((byteRead = buffer.read()) != -1) {
    builder.append((char) byteRead);
}
buffer.close();
System.out.println(builder.toString());
