- 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
- Whats the difference between interface and @interface in java?

- Implementing two interfaces in a class with same method. Which . . .
If both interfaces have a method of exactly the same name and signature, the implementing class can implement both interface methods with a single concrete method However, if the semantic contracts of the two interface method are contradicting, you've pretty much lost; you cannot implement both interfaces in a single class then
- 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 define an interface for an array of objects?
Yes, your example of defining an interface only for the particular items would be a more useful way to do it It would be quite rare to have an array of items, but not want to conveniently reference a single item Using a real array also exposes length on the interface, which will probably be used quite often

- How to implement a property in an interface - Stack Overflow
In the interface, there is no code You just specify that there is a property with a getter and a setter, whatever they will do In the class, you actually implement them The shortest way to do this is using this { get; set; } syntax The compiler will create a field and generate the getter and setter implementation for it
