Define a default constructor that initializes the fields color $($string$)$ and type $($string$)$ with the default values "Unknown" and "Undefined", respectively.

Ex: If the input is golden yak, then the output is:

Default values:

Color: Unknown, Type: Undefined

After mutator methods:

Color: golden, Type: yak

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