You can use interfaces in Java as a way to achieve polymorphism. I will get back to polymorphism later in this text. Java Interface Example Here is a simple Java interface example: public interface MyInterface { public String hello = "Hello"; ...

Adds a data type to a class− This situation is where the term, tagging comes from. A class that implements a tagging interface does not need to define any methods (since the interface does not have any), but the class becomes an interface type through polymorphism. ...
In other words, the operation that T must support for the template to compile is the implicit interface of T. Compile-time Polymorphism: Because instantiating function templates with different template parameters leads to different functions being called, this is known as compile-time polymorphism. In...
