What is gained by writing an interface to a Queue ADT (Abstract Data Type), as opposed to simply writing a Queue class, to solve a problem.

Question

What will be an ideal response?

Answer 1

What is gained is code re-use. A well-defined interface can be re-used to implement queues that manage
many different types of elements, and whose queue operations can be implemented in different ways. Without a Queue
interface, every time a new queue is needed, a programming team has to ensure that they are providing all of the functionality of
a queue in their implementation.
