| What is a sealed class? What is an Abstract class? and that is a class that is not declared or sealed or abstract. |
| ||
| A class declared as sealed is one that cannot be inherited. An abstract class is one that cannot be instantiated- objects cannot be created from it- so it is only used as a template from which other classes can inherit. |

| Thank you very much, an interface is a class? |
| ||
| No, an interface is a set of declarations any class can implement. It's used to tell that any class that implements a given interface can perform a given task. As instance, any class that implements a iSortable interface, will be forced to have a "Compare" method, so any object of this class can be used on any sorting algorithm. this allows a sort of multiple-inheritance approach, while it keeps a clean and nicer inheritance model. |
