Is this just an abstract base class? Two interfaces with same method names and signatures. But implemented by a single class then how the compiler will identify the which method is for which interface?

An interface is two things:
42 the interface keyword indicates that you are declaring a traditional interface class in java.
Yes, your example of defining an interface only for the particular items would be a more useful way to do it. 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 that way . An interface promises nothing about an action! The source of the confusion is that in most languages, if you have an interface type that defines a set of methods, the class that.
It is a set of methods, but. An interface is a contract: Gui is graphical user interface and ui is just user interface. gui is a subset of ui. A good example of when exactly to use interfaces specifically in java would be ideal and any specific rulings that apply.
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. It would be quite rare to have an array of items, but not want to conveniently reference a single.
