Duration: 15:38 min
Description:
An interface is a named collection of abstract (not implemented) members. It is
declared with the keyword 'interface'. This video will cover the first part of
how interfaces are declared and how they can be implemented. When a class
implements an interface, it must provide implementation for all methods within
the interface. In other words, a developer cannot pick and choose which methods
to implement.
