Java HTTP Request : get content size

Question

I want to know if it's possible to get the size of a web page with a http request.

I use this to have oracle page length :

URL oracle = new URL("http://www.oracle.com/");
URLConnection yc = oracle.openConnection();
List<String> get = yc.getHeaderFields().get("content-Length");

But when I use this to a google page I do not have content-length in the header.

You must use the correct upper or lower cases. The field name is "Content-Length" not "content-Length". You can also use the getContentLength() method of the URLConnection object. This field should be used by any application that need to send a HTTP body, and google does it so. — Jean-Baptiste Yunès

Be aware that Google uses secured connections.

Content-Length is only going to be applicable if the response is not chunked. Generally static content will not be chunked, but in many cases dynamic content will not be chunked.

In the case of www.oracle.com, you will be redirected to www.oracle.com/index.html, which is static content and does provide Content-Length.
