In the class definition, initialize the private fields areaCode (integer) and number (integer) with the default values -1 and 1,
respectively.
Ex: If the input is 781 8235964, then the output is:
Default values:
Area code: -1, Number: 1
After mutator methods:
Area code: 781, Number: 8235964
Note: The class's print() method is called before and after the input is passed to the setters.
