Whats the difference between interface and @interface in java? 42 The interface keyword indicates that you are declaring a traditional interface class in Java The @interface keyword is used to declare a new annotation type See docs oracle tutorial on annotations for a description of the syntax See the JLS if you really want to get into the details of what @interface means
oop - What is the definition of interface in object oriented . . . 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 implements it "repeats" the same methods (but provides definition), so the interface looks like a skeleton or an outline of the class
How can I define an interface for an array of objects? OP asked for interface, I assume it is extended with other properties and methods, you cannot do that with a type and also type is more limited than an interfaces in terms of general usability
What is the difference between an interface and abstract class? An interface is a good example of loose coupling (dynamic polymorphism dynamic binding) An interface implements polymorphism and abstraction It tells what to do but how to do is defined by the implementing class
How can I use interface as a C# generic type constraint? That having been said, an interface constraint on T should allow reference comparisons between T and any other reference type, since reference comparisons are allowed between any interface and almost any other reference type, and allowing comparisons even that case would pose no problem
Should one interface inherit another interface - Stack Overflow Interface inheritance is an excellent tool, though you should only use it when interface B is truly substitutable for interface A, not just to aggregate loosely-related behaviors It's difficult to tell whether it is appropriate for your specific case, but there's nothing wrong using the practice in principle You see it in the first-rate APIs all the time To pick just one common example
