The person writing the interface says, hey, i accept things looking that way , and the person using the interface says ok, the class i write looks. Is this just an abstract base class? Two interfaces with same method names and signatures.

Yes, your example of defining an interface only for the particular items would be a more useful way to do it.
A good example of when exactly to use interfaces specifically in java would be ideal and any specific rulings that apply.
How do i setup a class that represents an interface? An interface is a contract: But implemented by a single class then how the compiler will identify the which method is for which interface? It would be quite rare to have an array of items, but not want to conveniently.
It is a set of. 42 the interface keyword indicates that you are declaring a traditional interface class in java. Gui is graphical user interface and ui is just user interface. gui is a subset of ui. An interface is two things:
The @interface keyword is used to declare a new annotation type.
Hi, interface and type, looks similar but interfaces can use for declaration merging and extends and implements which type cannot do. An interface promises nothing about an action!
