我目前正在尝试理解下面每个代码背后的逻辑。如果我是正确的，请告诉我并回答我的困惑。
urlConnection = (HttpURLConnection) url.openConnection();
//connection object is created. However, do not understand
//"manipulate parameters that affect the connection to the remote resource."
urlConnection.setRequestMethod("GET");
//set the method for the URL request. Not sure what that means!
//there are other strings that could be used, but not sure what each means,
//and couldn't the Java documentations didn't seem to have explanations either
urlConnection.connect();
//the actual connection the the remote object is made

开始http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol
