Yes I understand some verbosity is structural and won't change anything, for example

SomeClass x = new SomeClass();

won't make anything slower (ignoring auto for now)

Now, I read Java code and I can't help but wonder how things are harder

For example, setters and getters, what would be a simple memory write becomes a function call. Not complaining when you actually need it.

Reading the examples here (and those are not too bad) https://developer.android.com/reference/java/net/HttpURLConn... it seems you have to actually fight the API to get anything done

Why do you need to cast the return of a url.openConnection() to a HttpURLConnection? (I mean, how many connection types exist?)
