Do models need interfaces?

But the format and type of data object expected does not change, no matter how you create this object. Therefore model objects which carry the state would not need an interface, but service classes to create and load these model objects needs the interface.

Which are the interfaces?

In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these.

What is model GUI?

Why use an interface instead of a class?

Having interfaces separate from classes allows for clear separation between, well, the interface of an object and its implementation. Without them you would have no standard way to indicate that some class should not contain implementation details at all.

Who are command line interfaces best used by?

How many types of interface design models are there?
