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