Summary

An interface defines the contract for a class — the various members that a class must have, the result returned for each method, and so on. However, an interface does not provide the implementation for a class; the actual implementation is left to the implementing classes. This chapter presented different ways in which you can work with interfaces — implementing multiple interfaces, extending interfaces, casting to an interface, and so forth.
