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. Two interfaces with same method names and signatures.

The @interface keyword is used to declare a new annotation type. I wanted to do a generic comparison between an interface and an abstract class on the basis of their usage. This may be a generic oop question.
I know this is old, but a very important difference between an interface and an abstract class in c# is that, once you release an interface, changing the interface is a breaking.
42 the interface keyword indicates that you are declaring a traditional interface class in java. An interface is a contract: But implemented by a single class then how the compiler will identify the which method is for which interface? An interface promises nothing about an action!
It is a set of. You can refer to the article how to use interfaces in go (based on russ cox’s description of interfaces): An interface is two things: Gui is graphical user interface and ui is just user interface. gui is a subset of ui.
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 in java is a special type of abstract class, the interface provided the 100% abstraction but since the java introduce new features in java 8 the meaning of whole.
