1.  7.42 -

     Since all three calls to Overload.f match up to a method in class Overload based on their signatures the following outputs are created.

     f(int, int): a = 1

     f(int, int): b = 2

     f(int, double): a = 1

     f(int, double): b = 10.2

     f(double, double): a = 10.2

     f(double, double): b = 3.5

2.  Explain why two classes referenced by the same program can have methods with identical names.

    They can have the same name due to OVERLOADING.  Overloading allows same name use as long as the method signatures are different.  Since the name is the same, the signature must have different types, the number of parameters, or order of the parameters. (p. 344 (Ch. 7.6),  Cohoon).
