java - Difference between URLConnection, HttpURLConnection and HttpsURLConnection

Question

Answer 1

URLConnection is the base class.

HttpURLConnection is a derived class which you can use when you need the extra API and you are dealing with HTTP or HTTPS only.

HttpsURLConnection is a 'more derived' class which you can use when you need the 'more extra' API and you are dealing with HTTPS only.

All three of them are abstract, and implemented by specific classes you aren't privy to.
