This code produces the following output:
Calling through: object.
Figure 17-5 illustrates the duplicate interface methods being implemented by a single
class-level method implementation.

References to Multiple Interfaces
You saw previously that interfaces are reference types, and that you can get a reference to
an interface by casting an object reference to the interface type. If a class implements multiple
interfaces, you can get separate references for each one.
For example, the following class implements two interfaces with the single method
PrintOut
. The code in
Main
calls method
PrintOut
in three ways:
Through the class object
Through a reference to the
IIfc1
interface
Through a reference to the
IIfc2
interface
