It would be quite rare to have an array of items, but not want to conveniently reference a single. Two interfaces with same method names and signatures. An interface is two things:

But implemented by a single class then how the compiler will identify the which method is for which interface?
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 .
Hi, interface and type, looks similar but interfaces can use for declaration merging and extends and implements which type cannot do. 42 the interface keyword indicates that you are declaring a traditional interface class in java. How do i setup a class that represents an interface? 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.
An interface is a contract: Yes, your example of defining an interface only for the particular items would be a more useful way to do it. An interface promises nothing about an action! The @interface keyword is used to declare a new annotation type.
You can refer to the article how to use interfaces in go (based on russ cox’s description of interfaces):
A good example of when exactly to use interfaces specifically in java would be ideal and any specific rulings that apply. Is this just an abstract base class?
