Answer 1

I suppose method parameter accepts object wich extends JsonHttpResponseHandler object. And here is passing such new object generated pragrammatically as anonymous class. So it is legal in java.

See https://docs.oracle.com/javase/tutorial/java/javaOO/anonymousclasses.html#syntax-of-anonymous-classes
