The "default constructor" is the one automatically inserted by the compiler if you don't provide one yourself. So it's the first example. The second is a parameterless (or no-arg) constructor, but because you've provided it it isn't considered a default one.

The default constructor is inserted by the compiler if you do not provide any constructor yourself.
