Set up HTTP Cookie in Java

In my Java programming, I need to set up some pre-defined HTTP cookie so that I can tell the website what content I prefer on using HttpURLConnection, for example. This is what I do:

// Create my cookie
HttpCookie cookie = new HttpCookie("cookie_name", "cookie_value");
// So that the cookie applies to all pages

CookieManager cookieManager = new CookieManager();

CookieStore cookieStore = cookieManager.getCookieStore();
cookieStore.add(uri, cookie);

// Set my cookie manager that contains my cookie to be used system-wide

// From now on my cookie will be used for all connections to the web site denoted by uri.
