Define a default constructor that initializes the fields renter $($string$)$ and gasTank $($integer$)$ with the default values "Unstated" and $-1,$ respectively.

Ex: If the input is Mel $99,$ then the output is:

Default values:

Renter: Unstated, Gas tank: $-1$

After mutator methods:

Renter: Mel, Gas tank: $99$

Note: The class's print$()$ method is called before and after the input is passed to the setters.
