Constructor rule : when is this() inserted by compiler ?

As per one of the Rules of Constructors :

Every constructor has, as its first statement, either a call to an overloaded constructor ( this() ) or a call to superclass constructor( super() )

I know that compiler always insert super() as 1st statement, then what about this() when is that inserted by the compiler ?

It's never inserted automatically by the compiler.

this() calls the no-arguments constructor of the class from another constructor. That never happens automatically.

That's not true - it only does that if you don't explicitly call super(...) (with or without arguments) yourself.

Thanks a lot for your time.
