2. Java implements In Java, interfaces are ways to enforce a contract onto classes. Interfaces force the implementing classes to implement a certain behavior. To implement an interface, a class must use implements keyword. public class WorkerThread implements Runnable { //... } In Java, we ca...
out.println("Interface B"); } @Override public void showC() { System.out.println("Interface C"); } } Output: Interface A Interface B Interface C Interface Extends Multiple Interface in Java An interface can also implement (extend) multiple interfaces. Java allows to interface like class...
An interface is consist ofsingletonvariables (public staticfinal) andpublic abstractmethods. We normally prefer interface in real time when we know what to do but don’t know how to do. An interface cannot contain instance fields. Theclasseswhich implement the Interface must provide the method de...

Today, we will be learning how to implement properties in an interface in C#. Interfaces in C# can have many different properties, along with the access modifiers specifying how we should declare property availability within. The interface often acts as a default implementation of different members...
However, you must clearly understand what an interface is and how it is used before you can take advantage of the technique. Here we’ll explainthe basics of interfaces in OOP programming, and then how how to implement the technique of programming to the interface. ...

So how does polymorphism relate to a Java Interface? In Java, an interface allows classes that wouldn’t be conventionally related to have access to similar operations. In its simplest form, a Java interface is a template that can be easily utilized by the different classes that implement it....
