Setting “User-Agent” parameters for URLConnection for querying Google from a Java application

问题

I am trying to get the results back from a Google query, in Java as follows:

String urlquery = "https://www.google.com/search?hl=en&gl=us&tbm=nws&q=apples&oq=apples";
URL url = new URL(urlquery);
URLConnection connection = url.openConnection();
URLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_8; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.0.249.0 Safari/532.5");

But, I don't know how to set the "User-Agent" parameters above. From where do I get the values for my system? I just copied these values from some code I found online.

My system configuration is as follows: Mac OSX 10.8.3 Intel i7 Safari 6.0.3(8536.28.10)
