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
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
Typescript interface default values - Stack Overflow I have the following interface in TypeScript: interface IX { a: string, b: any, c: AnotherType } I declare a variable of that type and I initialize all the properties let x: IX = {
How do you declare an interface in C++? - Stack Overflow A good way to think of this is in terms of inheriting an interface vs inheriting an implementation In C++ you can either inherit both interface and implementation together (public inheritance) or you can inherit only the implementation (private inheritance) In Java you have the option of inheriting just the interface, without an implementation
