我已经阅读了Android的Security with HTTPS and SSL文档。我看到它一直在使用copyInputStreamToOutputStream(in, System.out);。那给我

URL url = new URL("https://wikipedia.org");
URLConnection urlConnection = url.openConnection();
InputStream in = urlConnection.getInputStream();
copyInputStreamToOutputStream(in, System.out);

copyInputStreamToOutputStream是什么意思？
